Sourav: correct - to my understanding the PortalNodeEvent mechanism can only "swap" events in and out of the event chain, and so is fairly limited in terms of IPC. What we've done to handle this limitation is, in a small set of cases, use the Navigation API to store some data in the global portal session so that it can be accessed by more than one portlet on a given page. For example: Navigation.getPortalRuntimeContext().getSession() View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4230827#...
