Modify EventResponse Interface to preserve window state changes accross multiple event invocations -------------------------------------------------------------------------------------------------- Key: GTNPC-109 URL: https://issues.jboss.org/browse/GTNPC-109 Project: GateIn Portlet Container Issue Type: Enhancement Components: API Affects Versions: 2.4.1.Final Reporter: Adam Kovari Priority: Minor Fix For: 2.4.3.Final Attachments: 00905214-src.zip If a portlet changes it's window state in the event processing phase, this state is not preserved as other portlets/events can be processed on the same page and then portal will override this changes. The spec says: PLT.12.4 EventResponse Interface ================================ The EventResponse interface extends the StateAwareResponse interface and adds the additional method setRenderParameters(EventRequest request). One thing to note is that if a portlet receives multiple processEvent calls while processing one client request the new portlet mode or window state that the portlet may have set, may be not validated by the portal between these multiple processEvent calls. This means that even if the portlet container may not throw an exception when the portlet sets a new portlet mode or window state that the portal may still not approve this portlet mode or window state change and call the portlet render method with a different portlet mode or window state. So the window state change can be preserved even accross multiple events invocation. Seems to be fine by the spec as shown above.
