public interface EventPortlet
EventPortletinterface allows portlets receiving events.
Events are part of the action processing and must be finished before the rendering phase can start. Portlets can receive events issued by other portlets or portlet container defined events.
Portlets should declare the events it would like to receive
supported-processing-event tag and events published
supported-publishing-event tag in the portlet
The event model is a loosely coupled model where the wiring between published and receiving events is done at the portal / portlet container level.
