[Jboss-dev-forums] [Design of JBoss Portal] - Re: Portlet intercommunication

[sven.schulz <nu...@jb...>]

Think of the Windows Explorer. There is a tree showing the directory structure and a detail view showing the contents of the selected folder. Now imagine that you would implement such an explorer within a portal (not necessarily for file systems). One way is to provide a portal for the tree structure and one for the detail view. When a user (so, yes the scope is per user) selects an element in the tree portal, the detail portal view is updated to show the details (e.g. files) of the element.

What I think of is some kind of messaging. I think a phased approach would be beneficial. In one of the phases portals may emit messages to channels. In a subsequent phase those messages may be received by polling the channels.
