Portlet events provides a powerful way to decouple portlets. After the process action phase, an optional event phase is executed by the portal to process any events generated and produced by portlets. We recommend that you read the portlet specification to learn more about portlet events.

Coordination of portlets via events is scoped by pages. When an event is produced by a portlet on a page, Simple Portal will locate all portlets on that very same page that can consume the produced event. Produced events and consumer portlets are matched using the event's qualified name as specified in portlet.xml.
