Author: julien(a)jboss.com Date: 2006-12-15 11:04:07 -0500 (Fri, 15 Dec 2006) New Revision: 5872 Added: trunk/portlet/src/main/org/jboss/portal/portlet/impl/state/producer/ProducerStateContextImpl.java Modified: trunk/core/src/main/org/jboss/portal/core/impl/portlet/state/PersistentState.java trunk/core/src/main/org/jboss/portal/core/impl/portlet/state/PersistentStateStore.java trunk/core/src/main/org/jboss/portal/test/core/state/ProducerTestCase.java trunk/portlet/build.xml trunk/portlet/src/main/org/jboss/portal/portlet/impl/state/producer/ProducerPersistenceManagerService.java trunk/portlet/src/main/org/jboss/portal/portlet/state/producer/ProducerPortletInvoker.java trunk/portlet/src/main/org/jboss/portal/portlet/state/producer/ProducerStateContext.java Log: improve the ProducerPersistenceManager interface definition : don't make the ProducerStateContext a class that inherits ProducerState (a POJO), but rather have the ProducerStateContext be an interface that own a ProducerState object.
