For the portlet to portlet communication -
I deployed the example in JBoss Portal 2.7.2 from:
http://blog.xebia.com/2009/04/19/inter-portlet-coordination-with-jsr-286/ [http://blog.xebia.com/wp-content/uploads/2009/11/RAD75PortletEvent.zip]
Portlets are displayed, but communication is not happening because processEvent is not being called.
Any suggestions are helpful.
