DCErrorHandlerImpl is failing to handle POJO DataControl method exceptions

Question

Hi All,
I need a help to understand Adf DCErrorHandlerImpl  and to resolve a particular issue in using it.
All what I am doing is, extending DCErrorHandlerImpl  class to handle the exceptions in data control and showing a message on the page.
1) Extended DCErrorHandlerImpl   & overridden reportException method
2) Extended FacesPageLifecycle to set errorhandler
3) Created a SitePortalADFPhaseListener class to create page life cycle & configured the life cycle in faces-config.xml
This works fine in the cases where DataContol methods used as Operation Binding & called from backing bean.
But when the a method is directly bound to the grid in the UI, reportException() does not handle the error.
Any idea why handler isn't called in this case?
Thanks & Regards
KP

I followed the steps given in oracle documentation. In the given Sample project, error handler is implemented for AppModule exceptions.
But what I have is custom Data Control created out of Java class. And it has a method which returns a list.
public class MyDataControl {
     public MyDataControl() {    
           super();
    public List<MyPojo> getData(){
           try{
                  List<MyPojo> list = new ArrayList<MyPojo>();    
                  list.add(new MyPojo("Name1","25"));
                  list.add(new MyPojo("Name2","30"));
                  return list;    
           } catch (Exception e){
                  e.printStackTrace();    
                 throw new JboException(e);    
Once I created a DataControl for MyDataControl class, created table by dragging and dropping Data(accessor for getData) from DataControl.
Now if any exception in getData method, I am throwing a JboException instance.
According to documentation this exception need to intercepted by reportException() of DCErrorHandlerImpl. But reportException is not called in this case.
