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

ipublic 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);
}

Thanks
