[jboss-user] [JBoss Seam] - conversationId and IPC Portlets

[frankr]

I have two portlets (PortletA and B) communicating using IPC where B is listening for events coming from A. Both portlets are using the same controller component and this component is set to conversation scope. PortletA contains a bunch of commandLinks that invoke action methods on the controller component and the view outcome is displayed in PortletB.

If I click any commandLink in PortletB, the conversation is correctly maintained, however if I click in PortletA the conversation is lost and a new one is created. The problem with this is that the number of conversations grows with every click which is not the most scalable solution ;-)


The commandLink URL in portletB contains the conversationId=8. When I click this link, the portlet renders correctly back to conversationId=8.

Debug out put confirms this:

After this the commandLink still contain conversationId=8, however when I click in the command link in PortletA:


  | ...

If I click the commandLink in PortletA for the second time it jumps two numbers to 21. I'm guessing this is because Seam assigns a temporary conversation by default for each portlet and I have two portlets.

How can I ensure that conversation propagation works properly using IPC? Is there someway I can restore the previous (correct) state in the portlet? Feedback appreciated.
