How to delete protlet from the code?

Question

Hi All,
I want to delete the portlet at runtime (means from code) so does anyone has any idea how to do it?
Scenario - I have home page, there I have 5-8 portlets so I want to provide functionality to end user so they can delete and add the same portlet. So, for that I have created one more portlet which is on another page, from that portlet I am deleting one specific portlet by passing it's portlet instance ID.
I have written following code to delete it but it doesn't work out. I am not getting any exception while executing below code but it doesn't delete the portlet , so when I go back to home page I can see that portlet. FYI, It prints all SOPs.
I have written following code in backing file which is at page level (not on Home page).
String LOOKUP_NAME = com.bea.p13n.management.ApplicationHelper.getApplicationName() +"."+
     com.bea.netuix.application.manager.persistence.PortalCustomizationManagerHome.LOOKUP_NAME;
     Object obj = JndiHelper.lookup(LOOKUP_NAME, com.bea.netuix.application.manager.persistence.PortalCustomizationManager.class);
     System.out.println("=========="+obj.getClass().getName());
     com.bea.netuix.application.manager.persistence.PortalCustomizationManagerHome home = (com.bea.netuix.application.manager.persistence.PortalCustomizationManagerHome)obj;
     System.out.println("[HomePageBacking][Home]"+home);
     com.bea.netuix.application.manager.persistence.PortalCustomizationManager portalCustomizationManager = home.create();
     System.out.println("[HomePageBacking][portalCustomizationManager]"+portalCustomizationManager);
     com.bea.netuix.application.manager.CustomizationContext customizationContext = new com.bea.netuix.application.manager.CustomizationContext(request);
     System.out.println("[HomePageBacking][customizationContext]"+customizationContext);
     customizationContext.setVisitorMode(true);
     System.out.println("-------getParameter--------"+request.getParameter("instanceID"));
     String instanceID = request.getParameter("instanceID");
     if(instanceID != null)
          com.bea.netuix.application.identifier.PortletInstanceId portletInstanceId = com.bea.netuix.application.identifier.PortletInstanceId.createPortletInstanceId(Integer.parseInt(instanceID));
          //portletInstanceId.setId(Integer.parseInt(instanceID));
          System.out.println("[HomePageBacking][customizationContext.isVisitorMode()]"+customizationContext.isVisitorMode());
          System.out.println("[HomePageBacking][portletInstanceId.getId()]"+portletInstanceId.getId());
portalCustomizationManager.deletePortletInstance(customizationContext, portletInstanceId);
with the last line of above code it should delete that portlet for that user but it doesn't work.
So, any one has any idea on this?? I appreciate your help.
Thanks,

Following is the code to delete the portlet at runtime of from your code.
String webApp = ApplicationHelper.getWebAppName(request);
ResourceContext resourceContext = ResourceContext.createResourceContext(request, true);
String deletePortletId = "XXXXXX"; // This you can get it from request or from session
List<ControlAction> actions = new ArrayList<ControlAction>();
com.bea.netuix.application.identifier.Id id = new PortletInstanceId(Integer.valueOf(deletePortletId).intValue());
actions.add(PageInstanceAction.removePlaceableFromPageInstance(pageControl, (PlaceableInstanceId) id, webApp,
                         new PortalPath(portalPath), new DesktopPath(desktopPath)));
portalControl.executeActions(actions, resourceContext);
I hope this will help someone who wants to delete portlet at runtime fron code.
Thanks,
