Presentation Model Customization (Siebel Open UI Training – Part 3)

In the third module of Siebel Open UI training series, we will discuss about Presentation Model Customization.

After you complete this module, you will know

– What is Presentation Model
– It’s role in Siebel Open UI
– Presentation Model Customization steps

We hope that you have a fair knowledge about Siebel Open UI Architecture. If not, we would suggest you to read our previous article on Siebel Open UI Architecture first. It will help you to understand this module better.

Well, lets start our discussion with Presentation Model definition.

What is Presentation Model in Siebel Open UI?

– It is a JavaScript file that determines how to apply business logic on metadata and run-time data given by client proxy.

– It is client side scripting, collection of properties and methods.

  • Property: It contains information about current state of each user interaction.
  • Method: It defines the characteristics that modify the state of the object. For example – if user chooses value A for the field X, then apply method to hide field Y.

– Presentation Model is completely Siebel repository independent object. Addition or deletion of business logic from Presentation Model file does not need SRF compilation.

– It does not do rendering of any physical HTML or CSS file.

– It captures client interactions, like did the user leave a control or did the user click on a link?

– It supports different logic for different platforms like desktop, mobile.

– It can call server side business service also whenever required.

Few business scenarios where you can use Presentation Model Customization:

– Add additional control or list column that is not provided by client proxy

Example: Add an additional column to delete multiple records at a time

– Capture field values and set properties

Example: If an user chooses the pick list value ‘A’ for the field X, then hide the field Y

– Interact with Siebel Server

Example: Call server side business service

Before we discuss Presentation Model Customization steps, let us tell you few terminologies. We will use these through out our Siebel Open UI training series.

Terminology:

JavaScript API:

– JavaScript API gives a set of JavaScript functions to access and manipulate client side objects.

– In Siebel Open UI, JavaScript API replaces the browser scripting.

– Example : control.GetName() – GetName function returns the control name.

FieldChange(control, field value) modifies the field value of the control.

NameSpace:

– It is the place to maintain all Siebel objects instantiated in client cache.

Class:

– It instances Siebel object with unique name.

– In Javascript, there can be only one instance of a class at a particular time.

Good to know: JavaScript is a class-less language though functions can be used to simulate Class concept. Everything in JavaScript is treated as object.

Constructor:

– It instantiates and defines methods for the class.

Renderer Key Registration:

– It determines what all JavaScript files need to download on the browser.

Now we will discuss Presentation Model Customization step by step with an example.

Example: On Contact Form Applet, if Status field has any value, show the field ‘WorkPhoneNum#’ else hide it.

This is two step customization – first we will build a Presentation Model file to capture the Status field value (in this module) and then pass the value to Physical Render to hide or show the field ‘WorkPhoneNum#’ (in next module).

Steps for Presentation Model Customization:

1) Verify the object class does not exist

2) Add the class to Siebel namespace

3) Define the Presentation Model File location and other dependencies if any

4) Add constructor function within the class

4.1) Declare the class constructor as function

4.2) Inherit the super class constructor

4.3) Declare the class as an extension of default Presentation Model

4.4) Initialize INIT method to add properties and methods to the class

4.5) Add script for the custom method/s

Step 1: Verify the object class does not exist

– First you check whether the class has already been implemented or not. This should be the first statement to avoid any possible conflict.

Syntax:

if( typeof( SiebelAppFacade.custom_class_name ) === “undefined” ) {

Script for our example:

// Verify same Presentation Model class is not defined yet

if( typeof( SiebelAppFacade.ShowHideFieldsPM ) === “undefined” ){

Step 2: Add the class to Siebel namespace

– Every class must be added to the ‘SiebelAppFacade’ namespace.

– Use ‘NameSpace()’ function to do this

Syntax:

SiebelJS.Namespace( “SiebelAppFacade.custom_class_name” );

Script for our example:

// Add the class to the SiebelAppFacade namespace

SiebelJS.Namespace( “SiebelAppFacade.ShowHideFieldsPM”);

Step 3: Define the Presentation Model file location and other dependencies if any

– ‘Define’ method identifies the modules that Siebel Open UI uses to locate the Presentation Model file and other dependent JS files

– It must have a return statement like return “SiebelAppFacade.custom_class_name”;

Syntax:

define (Module_name,List_of_dependencies,Function);

  • Module_name is the Presentation Model file name with file path but without file extension.
  • List_of_dependencies is an array of all dependent modules required to execute Presentation Model JS file. If there is no dependency, keep it blank.
  • Function identifies the function name and returns an object.

Script for our example:

// Define the presentation model file location and other dependencies if any

define(“siebel/custom/ShowHideFieldsPM”, [], function () {
— Write the code here—
return “SiebelAppFacade.ShowHideFieldsPM”;
});

Step 4: Add constructor function within the class

4.1) Declare the class constructor as function

4.2) Invoke the super class constructor

4.3) Declare the class as an extension of default Presentation Model

4.4) Initialize INIT method to add properties and methods to the class

4.5) Add script for the custom method/s

Step 4.1: Declare the class constructor as function

– Declare the class constructor as a child of SiebelAppFacade

– It must have a return statement

Syntax

SiebelAppFacade. custom_class_name = ( function(){
— Writ the code here—
return custom_class_name; } ());

Script for our example:

// Declare the ShowHideFieldsPM class as function

SiebelAppFacade.ShowHideFieldsPM = ( function(){
— Write the code here—
return ShowHideFieldsPM; } ());

Step 4.2: Invoke the super class constructor

– When Open UI calls a custom constructor, it passes a proxy object. Custom constructor uses this proxy object to instantiate as-delivered objects.

Syntax

function custom_class_name ( proxy ){
SiebelAppFacade. custom_class_name.superclass.constructor.call( this, proxy ); }

Script for our example:

// Call the superclass constructor

function ShowHideFieldsPM( proxy ){
SiebelAppFacade.ShowHideFieldsPM.superclass.constructor.call( this, proxy ); }

Step 4.3: Declare the class as an extension of default Presentation Model

– Use SiebelJS.extend() to declare the class as an extension of Presentation Model

– Extended class can access all pre built functions of default PM

Syntax

SiebelJS.Extend(custom_class_name, SiebelAppFacade.PresentationModel );

Script for our example:

//Extend the class so that it can access all pre built functions

SiebelJS.Extend( ShowHideFieldsPM, SiebelAppFacade.PresentationModel );

Step 4.4: Initialize INIT method to add properties and methods to the class

– Declare the INIT function of the custom class

Syntax: Custom_Class_name.prototype.Init = function(){

– Call Super class INIT function to initialize as-delivered functionalities

Syntax: SiebelAppFacade.Custom_Class_name.superclass.Init.call( this );

– You can create properties for the class if required

Syntax: this.AddProperty( “Property Name”, “” );

– You can also override super calss methods

Syntax: this.AddMethod( “Name of the method to override”, custom method name, { sequence : false, scope : this } );

Script for our example:

ShowHideFieldsPM.prototype.Init = function(){
SiebelAppFacade.ShowHideFieldsPM.superclass.Init.call( this );
this.AddProperty( “ShowHideStatus”, “” );
this.AddMethod( “ShowSelection”, SelectionChange, { sequence : false, scope : this } );
this.AddMethod( “FieldChange”, OnFieldChange, { sequence : false, scope: this } );
};

Step 4.5 Add script for the custom method/s

– Write the script for all custom methods, specified in INIT function

Syntax:

function CustomMethod(){
— Write the code here — }

Script for our example:

// Custom method to execute when next record is selected

function SelectionChange(){
var controls = this.Get( “GetControls” );
var control = controls[ “Status” ];
var value = this.ExecuteMethod( “GetFieldValue”, control );
this.SetProperty( “ShowHideStatus”, ( value ? true: false ) );
}

//Custom method to execute when field value changes

function OnFieldChange( control, value ){
if( control.GetName() === “Status” ){
this.SetProperty( “ShowHideStatus”, ( value ? true: false ) );
}

Here is the complete script used in the example:

/*————————— Presentation Model Customization to Show/Hide a field ————————*/

// Verify same Presentation Model class is not defined yet 

if( typeof( SiebelAppFacade.ShowHideFieldsPM ) === “undefined” ){

// Add the class to the SiebelAppFacade namespace 

    SiebelJS.Namespace( “SiebelAppFacade.ShowHideFieldsPM” );

// Define the Presentation Model file location and other dependencies if any

    define(“siebel/custom/ShowHideFieldsPM”, [], function () {

// Declare the ShowHideFieldsPM class as function 

        SiebelAppFacade.ShowHideFieldsPM = ( function(){

// Call the super class constructor 

            function ShowHideFieldsPM( proxy ){

                SiebelAppFacade.ShowHideFieldsPM.superclass.constructor.call( this, proxy );

            }

//Extend the class so that it can access all pre built functions

            SiebelJS.Extend( ShowHideFieldsPM, SiebelAppFacade.PresentationModel );

// Initialize the object to add properties, methods

            ShowHideFieldsPM.prototype.Init = function(){

                SiebelAppFacade.ShowHideFieldsPM.superclass.Init.call( this );

                this.AddProperty( “ShowHideStatus”, “” );

                this.AddMethod( “ShowSelection”,  SelectionChange, { sequence : false, scope : this } );

                this.AddMethod( “FieldChange”,  OnFieldChange, { sequence : false, scope: this } );

            };

// Custom method to execute when next record is selected

            function SelectionChange(){

                var controls = this.Get( “GetControls” );

                var control = controls[ “Status” ];

                var value = this.ExecuteMethod( “GetFieldValue”, control );

                this.SetProperty( “ShowHideStatus”, ( value ? true: false ) );

            }

//Custom method to execute when field value changes

            function OnFieldChange( control, value ){

                if( control.GetName() === “Status” ){

                    this.SetProperty( “ShowHideStatus”, ( value ? true: false ) );

                }

            }

            return ShowHideFieldsPM;

        } ());

        return “SiebelAppFacade.ShowHideFieldsPM”;

    });

There are few frequently used Presentation Model Methods that every developer should know. We have discussed such methods in an another article – Presentation Model Methods.

What is ActiveX

ActiveX is nothing but a small piece of code(better known as Add-ons), created by Microsoft. If you have Internet Explorer installed on your computer, then ActiveX is also installed. Purpose of this ActiveX is to improve the browsing experience but it only works with Microsoft applications like MS Word, Excel, PowerPoint, Internet Explorer.  The Idea behind ActiveX is that same piece of code can be used in more than one place.

For Example, a spell checker functionality is required in MS Word as well as in e-mail application like Microsoft Outlook. So instead of writing same code twice, write a spell checking functionality in one place (i.e Windows Operating System) and call spell checker object wherever it is required.
ActiveX technology started as Object Linking and Embedding (OLE). In earlier version of windows, OLE used for cross application functions like Cut , Copy, Paste. Now a day, OLE has been transformed into Compound Object Module (COM). Spell checker is an example of COMs. It is an independent program in windows which can be used by any windows applications. ActiveX control is another COM which is used in larger applications. 

For example, if you want to play flash files(.swf) in Internet Explorer, you need Adobe Flash player installed on your system first, as IE cannot play flash files directly. But if the whole website is built in flash and you don’t want to install Adobe Flash Player, then IE gives you an option to download and install Flash ActiveX at your OS level. After that IE can play the files in the browser itself.

As it is a piece of code, there is a risk of misuse also. Using ActiveX, applications/websites can access your personal information, also it could throw unwanted pop-ups. So before installing any ActiveX, make sure it is trust worthy.
How to install ActiveX ? 
When any application needs ActiveX control, IE displays a dialog box asking your permission to install, provided Pop-Up blocker option in IE level is not set to ‘Yes’. Right click on the dialog box and click on ‘Install ActiveX Control’ option to install it.

How to uninstall ActiveX ?
Open Internet Explorer and then goto Tools > Manage Add-ons option. You can see the list of all add-ons, installed in your system. Select the ActiveX control you want to delete and then either click on Delete option or Disable.  

SBL-EAI-08032: WSDL cannot be generated for Argument having Data Type ‘Hierarchy’

Error Message: WSDL cannot be generated for Argument having Data Type ‘Hierarchy'(SBL-EAI-08032)
    – This is another common issue in Siebel when you try to generate WSDL from web client 

Reason: You can not generate WSDL for the argument with data type ‘Hierarchy’

Solution: Here you have two options to fix it. You can choose one which is best suitable in your case.
    – Change the argument/property type from Hierarchy to Integration Object and try to generate WSDL
    – Add XML conversion step to change the XML hierarchy to Integration object. You can use BS ‘EAI Integration Object to XML Hierarchy Converter’ and method ‘XMLHierToIntObjHier’ or ‘EAI XML Converter’ with method ‘XMLHierToIntObjHier’.

Siebel Open UI Architecture (Siebel Open UI Training – Part 2)

In our previous article, we have discussed about what is Siebel Open UI and its benefits. Here we will talk about Siebel Open UI Architecture and its various building blocks. Also we will discuss architectural difference between Siebel HI and Open UI client.

Siebel Open UI Architecture key components:

It includes all components of traditional Siebel client, plus Open UI specific components.

  1. Application Object Manager(AOM)
  2. Siebel Web Template(SWT) file
  3. JavaScript(JS) file
  4. Cascading Style Sheet (CSS) file
  5. Open UI client
    – Proxy
    – Presentation Model
    – Physical Renderer
  6. Manifest file

We will discuss all these one by one.

1. Application Object Manager (AOM)

– This is the most important server component. In Open UI, it behaves exactly the same way like our traditional Siebel client. AOM processes user requests with the help of other components like Data Manager, Siebel Web Engine.

– In our previous module, we have already discussed that below two parameters must be set to TRUE for Open UI Object Manager component.

EnableOpenUI = TRUE
HighInteractivity = TRUE

Our Recommendation: Instead of updating the existing object manager directly, copy it and add above two parameters to enable Open UI mode . Also you create a new virtual directory in Siebel Web Server to support Open UI Object Manager.

2. Siebel Web Template(SWT) file

– Siebel Web Template file defines the layout and format of the elements to display on UI. It provides the placeholders for Siebel objects like views, applets, controls but does not contain any data. These SWT files are nothing but HTML files with Siebel tags. Siebel Open UI uses newer version of SWT files that no longer contain any explicit layout information.

Original SWT file has explicit tags like tables, boundaries where Open UI SWT file has ‘div’ tag. It allows CSS files to control the layout.

– SWT files are located under \siebsrvr\WEBTEMPL

  • WEBTEMPL folder contains original SWT files
  • OUIWEBTEMPL folder, inside WEBTEMPL contains Open UI related SWT files
  • CUSTOM folder, inside OUIWEBTEMPL contains all custom SWT files

To know more about Siebel Web Template, read this: Overview of Siebel Web Templates

3) Cascading Style Sheet (CSS) file

– CSS is a style language that defines the layout of web pages, such as font, color, height, width

– Benefits of CSS:

  • Reusable, one CSS file could be used for multiple web pages
  • Modify style definition in one place and change will be reflected in all web pages
  • Different layout for different media types like mobile, desktop
  • Easy to build, notepad is sufficient to write css file

– Open UI uses CSS to build the layout of HTML files dynamically.

– CSS files are located in the web server under \webmaster\files\<lang> and \eappweb\PUBLIC\<lang>\FILES.

– For Siebel developer client, path is \client\PUBLIC\<lang>\files.

4) Java Script (JS) file

– JavaScript is a client side programming language used in web applications. It enhances the users experience of the web pages.

– In Siebel Open UI, JS files are used to add client side businessand validation and render the application in the web browser

– Oracle provided JS files deliver out of box functionalities. Developers can build custom JS files to leverage the functionalities.

– Beside Javascript, developers can use JQuery also.

– JS files are located in Siebel Server under \siebsrvr\public\<lang>\<build>\SCRIPTS

  • SCRIPTS folder contains original (High Interactivity) JS files
  • siebel folder, under SCRIPTS contains Open UI related vanilla JS files
  • custom folder, under \SCRIPTS\siebel contains all custom js files
  • 3rdparty folder, under SCRIPTS contains all 3rd party provided js files

– For Siebel developer client, JS files are located in \client\<lang>\<build>\SCRIPTS

Note: Traditional browser script is different from Open UI related JavaScript. Developers can use both in Siebel Open UI. But Oracle recommends to use JavaScript only for client side validation.

5) Siebel Open UI client:

– Open UI client is a Siebel engine that runs within the browser to enhance user experience and data validation

  • Binds data to the presentation layout
  • Caches data locally
  • Applies client side business logic

– It consists of 3 elements

  • Client Proxy
  • Presentation Model (PM)
  • Physical Renderer (PR)

5.1) Client Proxy

– It works as an interface to the Siebel Server.

– It gets run-time data and metadata from Siebel server and passes it to Presentation Model.

  • Run-time data is the actual data from Siebel database that users see in views/applets
  • Metadata specifies the column name and other details like required, readonly

– It is Oracle provided and must not be modified by users.

5.2) Presentation Model

– It is a JavaScript file that determines what business logic to be applied on metadata and run-time data coming from Siebel server.

– It captures client interactions such as

  • Did the user leave a control?
  • Did the user click on the link?

– It is collection of Properties and Method

  • Properties: It contains information about current state of each user interaction.
  • Method: It defines the characteristics that modify the state of the object. For example – if user chooses value A for the field X, then apply method to hide field Y.

– It supports different logic for different platforms

5.3) Physical Renderer

– It is a JavaScript file that Open UI uses to render application on the browser
– It can display the same set of records in different ways

  • List Applet
  • Carousal
  • Calendar
  • Mind Map

– Like Presentation Model, it also supports different behaviors for different devices like Desktop, Mobile

6) Manifest file

– It uses an unique key to determine which JavaScript file/s to download to the client

– Earlier version of Siebel Open UI Innovation Pack 2013 (8.1.1.11) has three manifest files under \seibsrvr\OBJECTS directory

  • Core_manifest.xml: As delivered listing of JS files and should not be modified by developers
  • Custom_manifest.xml: It specifies the key name and JavaScript file mapping
  • Manifest_extensions.map: It is the place to register Applet/key combination

– From Open UI Innovation Pack 2013, you do not need to modify manifest file anymore. Rather you configure it from Open UI client itself – Administration-Application||Manifest Administration.

We will discuss more about Presentation Model, Physical Renderer and Manifest File in subsequent modules.

Siebel Open UI Architecture

Major changes in Siebel Open UI Architecture:

  1. Open UI supports all modern browsers, not just Internet Explorer
  2. ActiveX controls are replaced by JavaScript controls
  3. ActiveX proxy is replaced by JavaScript proxy
  4. In Siebel Open UI Architecture, layout is not part of Siebel Web Templates any more

So far we have discussed various building blocks of Siebel Open UI Architecture and how it differs from Siebel HI client. If you have any doubt, please fell free to comment below.

Next we will discuss the architectural flow with an example – Navigating to My Opportunities view. Suppose you have clicked on ‘My Opportunities’ to open My Opportunities View. Now Siebel Open UI performs below steps to render ‘My Opportunities View’ on the browser.

Step 1: Presentation Model passes the request to the client proxy

Step 2: Proxy sends the request to Siebel Server

Step 3: Siebel Server processes the request and sends the result back to proxy

Step 4: Proxy reads the manifest file and downloads all required JS files

Step 5: Presentation Model applies the business logic on the result set and sends it to Physical Renderer

Step 6: Physical Renderer prepares the final HTML file with the reference of CSS files

Step 7: Result is displayed on the browser

Step 1: Presentation Model passes the request to the client proxy

– Presentation Model captures the event ‘on mouse click’ and sends the request to client proxySiebel Open UI Architecture - Examples-Step 1

Step 2: Proxy sends the request to Siebel Server

– First proxy checks the client cache memory for the necessary data to fulfill client request

– If required data is available in the cache memory, it directly goes to Step 4. Otherwise proxy sends the request to Application Object Manager on Siebel Server to get the record set.Siebel Open UI Architecture - Examples-Step 2

Step 3: Siebel Server processes the request and sends the result back to proxy

– Application Object Manager processes the request and sends back the record set to proxy

– Record set contains metadata and runtime data

  • Metadata: Object definitions like Columns, Applets, Views
  • Runtime data: Actual user data from Siebel databaseSiebel Open UI Architecture - Examples-Step 3

Step 4: Proxy reads the manifest file and downloads all required JS files

– Proxy reads the manifest file and downloads all JS and corresponding CSS files to display opportunity records.Siebel Open UI Architecture - Examples-Step 4

Step 5: Presentation Model applies the business logic on the result set and sends it to Physical Renderer

– Once data is received and files are downloaded, Proxy sends the notification to Presentation Model

– Presentation Model executes JS files to apply business logic on received dataSiebel Open UI Architecture - Examples-Step 5

Step 6: Physical Renderer prepares the final HTML file with the reference of CSS files

– Presentation model sends the notification to Physical Renderer to generate HTML files with the reference of CSS files.Siebel Open UI Architecture - Examples-Step 6

Step 7: Result is displayed on the browser

– The final HTML page ‘My Opportunities View’, embedded with JavaScript, CSS and Data, is displayed on the browser.Siebel Open UI Architecture - Examples-Step 7
