Raise a Client Event 

The following example demonstrates how to raise a portal event:

WDPortalEventing.fire ("urn:com.sap.tc.webdynpro.test.portal",                          "TestEvent",                          "AParameter");

You can fire a portal event at any time in your Web Dynpro application. The event is transported with the next response to the client. You can also raise more than one portal event in one request-response cycle. Normally, you will fire a portal event in a Web Dynpro action event handler (for example, pressing a button).
