wiring portlet

We had a task flow A, which successfully communicated with task flow B using contextual event. Now we create portlet A based on task flow A and portlet B based on task flow B using create Portlet Entry functionality in JDeveloper. When we put portlet A and portlet B together in WCP page, the 2 portlets do not talk together.

Yes, we are able to see the contextual event created by task flow A but not able to see the event handler method created by task flow B on our WCP page. It seems the contextual event is created but the event handler is not picking.
