Yes, exactly. Events mechanism need to be deterministic. And a portlet emitting an event should not worry about the various event wirings. If we take your example further, Page A, Page B, page C with respective Portlet A, Portlet B, Portlet C say an event submitted from a link on Portlet A is wired to Portlet B and Portlet C, on which page will you land ? (ordering of wires in not an option ;) ) If you are looking for a solution that would work accross all portals, you won't be able to achieve that, you can create cross-portal-vendor *portlets* but not cross-portal-vendor *portals* (unless you defined a complex level of abstraction between vendors) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238407#...
