Subject [jira] Created: (OPENJPA-754) Un-scheduled pre/postUpdate callbacks from persist.
Date Tue, 28 Oct 2008 21:00:46 GMT
Un-scheduled pre/postUpdate callbacks from persist.
---------------------------------------------------

                 Key: OPENJPA-754
                 URL: https://issues.apache.org/jira/browse/OPENJPA-754
             Project: OpenJPA
          Issue Type: Sub-task
          Components: kernel
    Affects Versions: 1.2.0, 1.1.0, 1.0.3, 1.0.4, 1.1.1, 1.2.1, 1.3.0, 2.0.0
            Reporter: Albert Lee
            Assignee: Albert Lee
             Fix For: 1.3.0, 2.0.0


In some use case, an unexpected pre/postUpdate callback event will be fired. 

The following operations demonstrate the scenario:

			em.getTransaction().begin();
			// Create and persist a new Message entity
			Message message = new Message("Hello Persistence!");
			message.setId(1);
			em.persist(message);
			em.flush();
			// Create and persist another new Message entity
			message = new Message("Hello Persistence 2!");
			message.setId(2);
			em.persist(message);
			em.getTransaction().commit();

			em.getTransaction().begin();
			message.setMessage("Mutated 2!!");
			em.getTransaction().commit();


** PrePersist - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=null
** PostPersist - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=1
** PrePersist - Message: id=2, m=Hello Persistence 2!, create=null, updated=null, v=null
** PreUpdate - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=1
** PostPersist - Message: id=2, m=Hello Persistence 2!, create=null, updated=null, v=1
** PostUpdate - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=1

** PreUpdate - Message: id=2, m=Mutated 2!!, create=null, updated=null, v=1
** PostUpdate - Message: id=2, m=Mutated 2!!, create=null, updated=null, v=2
