I'm trying to locate a ProcessInstance inside a List container using the "contains" method but the instance is not found. Looking in the equals method of the ExecutionImpl I saw that the EqualsUtils.equals static method is used for that purpose and it's using the object pointer instead the object hibernate key to compare objects. I think the implementation of the EqualsUtils.equals method should compare objects using its hibernate key, doesn't it? Idea: | ClassMetadata entity1Metadata = sessionFactory.getClassMetadata(entity1.getClass()); | Object entity1Key = entity1Metadata.getIdentifier(entity1, EntityMode.POJO); | | ClassMetadata entity2Metadata = sessionFactory.getClassMetadata(entity2.getClass()); | Object entity2Key = entity2Metadata.getIdentifier(entity2, EntityMode.POJO); | | return entity1Key.equals(entity2Key) | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4266872#...
