OAF : Programatically Add Region to OA Page

Sometimes in OAF, you want to add a region to OA Page.

For example i had a requirement to add employee summary region to another page.
Employee Summary Page exists at MDS at this path"/oracle/apps/per/selfservice/common/webui/AsgSummaryRN".

Application module that is used with this region is "oracle.apps.per.selfservice.common.server.SummaryAM" 

I wrote the following code to add this page to another page at controller of OA page

public void processRequest(OAPageContext pageContext, OAWebBean webBean)

 {

 super.processRequest(pageContext, webBean);

 OATableLayoutBean empSummaryBeean =

  (OATableLayoutBean)this.createWebBean(pageContext,

             "/oracle/apps/per/selfservice/common/webui/AsgSummaryRN",

             "AsgSummaryRN", true);

 empSummaryBeean.setApplicationModuleDefinitionName("oracle.apps.per.selfservice.common.server.SummaryAM");

 empSummaryBeean.setStandalone(true);

 webBean.addIndexedChild(0, empSummaryBeean);

}
