JBoss Portal IPC enables a one-to-one relationship between portlets.
I have been thinking on how can I cause multiple portlets to listen to one action.
Is there a workaround for this?
yes, you can do it, as a message inter-exchange (and not as events).
see this post : http://jboss.org/index.html?module=bb&op=viewtopic&t=87442
the librairy proposed is working well.
