Inter Portlet Communication (multiple war) does not work in case the portlet channel is minimized or closed. (#6271542)Description:
Currently, the scope of the event processing is limited to the portlets in the same tab. Hence, portlets in minimized or closed channel do not appear in the list of portlets participating in inter portlet communication. Inter Portlet Communication will not work in case the portlet channel is minimized or closed since the events will not be sent to closed or minimized channels.
