Stack That Siebel Open UI Uses to Render Objects

The following figure describes the stack that Siebel Open UI uses to render objects. It uses the applet object as an example.

Stack That Siebel Open UI Uses to Render Objects: This image is described in the surrounding text.

As shown in this figure, the stack that Siebel Open UI uses to render objects includes the following:

  1. Physical layout and styling. Allows you to use HTML to display content, JavaScript to customize logic, and cascading style sheets to customize layout and styling in the client. You can position or hide controls to achieve almost any layout requirement.

  2. Physical renderer. For more information, see About the Physical Renderer and About Plug-in Wrappers.

  3. Presentation model. For more information, see About the Presentation Model.

  4. Proxy objects. Includes object instances for the client proxy. Each of these instances represents an instance of a corresponding repository object that resides on the Siebel Server. Example objects include a view, applet, business object, or business component. A proxy object includes only enough logic to allow the client to use the same functionality that the server object uses, including the data and metadata that the server object requires. A proxy object exposes the interface for scripting in the client, but it does not allow you to significantly modify the physical user interface. You can customize only the information that flows from the Siebel Server to the client. You cannot customize how Siebel Open UI uses the metadata or data in the proxy object to render the physical user interface. In this example, proxy objects include the applet proxy and business component proxy that contain data and metadata from the Server Response property set. For more information, see Browser Script Compatibility.

  5. Siebel Property Set. A hierarchy that Siebel Open UI uses to communicate between objects that reside on the Siebel Server and the proxies that reside in the client.

  6. SWE runtime applet object. Exposes scripting interfaces that allow you to modify the applet so that it can control the business component or business service that this applet references. The applet that resides on the Siebel Server gets a request from the proxy applet instance that resides in the client. If necessary, it sends the request to a business component or business service. Siebel Open UI does not currently include a scripting interface that allows you to modify the property set that the applet sends to the client.

  7. Applet metadata. The applet object in the Siebel Runtime Repository that contains information that Siebel Open UI uses to bind the user interface to the business component. Siebel Open UI maps this information through business component fields. This binding can include only a one-to-one mapping between one applet control and one business component field. Siebel Open UI does not allow more complex bindings. You can configure Siebel Open UI to get data through a presentation model in the client to develop functionality that is similar to the functionality that a more complex binding provides.
