Passing Data Back from a WebDynpro App to a Portal App

Question

Hello all,
We have an iView in the portal that has a link to a webdynpro application.  When the link is clicked, it opens the webdynpro app in a new window.  When a user selects data on this window and clicks a button, I want that data selected transferred to a specific field on calling window. 
Prior to using webDynpro, we were able to do this by using the code below on the called page.
<SCRIPT language='JavaScript'>
function SelectUser() {
   var selectedUserAdmcd=document.all["EMP_ADMCD_RET"].value;
   window.opener.document.forms[0].ADMIN_HR_CODE_NEW.value=selectedUserAdmcd;     
Any suggestions will be appreciated.
Thanks,
Mike

Hi Mike,
  The SAP Enterprise Portal 6.0 supports client-side eventing. I dont thhink  you cannot write Java Script code in a Web Dynpro application, a Java wrapper enables you to implement portal eventing. You can subscribe to and unsubscribe from specific portal events. This means that the SAP Enterprise Portal can react to an event that is triggered by a Web Dynpro application.
Sample code for the same
In the sender application, On action of the button click event.
String parm=wdContext.currentContextElement().getInput();
WDPortalEventing.fire ("urn:com.sap.tc.webdynpro.example.portaleventing", "Event Name ", parm);
In the listener application
In the Init method subscribe the portal event
WDPortalEventing.subscribe("urn:com.sap.tc.webdynpro.example.portaleventing","Event Name ", wdThis.wdGetReactPortalEventingAction() );
Create an action ReactPortalEventing. Add the parameter data of  type java.lang.String.
wdContext.currentContextElement().setOuput(dataObject);
The value of the element Input recieved in the Sender application will mapped to the element Output  of the  listener application.
