The events in this section are provided by the JavaScript EPCM object that exists on every portal page, when the EPCF service is activated.
External portal applications that have no EPCM object must use the regular page client API.
The events expect a parameter in the form:
{Id : "iview id" , Window : iview HTML frame window}
If Id is not null, the window parameter is ignored. This parameter was designed to support Java portal applications and external iViews that use the URL isolation mode.
Depending on the type of the iView, set the parameter as follows:
For a Java portal application, specify the iView Id and set the Window parameter to null.
For an external iView, set the iView Id to null and the Window parameter to self.
To get the iView ID, use the following method of the server-side Portal Runtime (PRT) API :
request.getComponentContext().GetContextName ();
For background information, see:
Enterprise Portal Client Framework (EPCF)
The page builder has the following events:
Opens an iView in a new window.
This event corresponds to theOpen in new window option of the iView tray.
