ObjectChangeSet always null [message #555708]

Hi All,

I need to get object changed set before calling entityManager merge() method, so before the transaction is committed.

I always get null when calling getObjectChangeSetForClone(objectToBeUpdated).

The code I'm using is:
JpaEntityManager jpaEntityManager = (JpaEntityManager)em.getDelegate();

UnitOfWorkChangeSet changeSet = (UnitOfWorkChangeSet)jpaEntityManager.getUnitOfWork().getCur rentChanges();

ObjectChangeSet objChangedSet = changeSet.getObjectChangeSetForClone(objectToBeUpdated);

objChangedSet is null no meter if the objectToBeUpdated is dirty or not.

There is any additional configuration property I have to add in persistence.xml to get this working?

How can I get the object change set without extending DescriptorEventAdapter?

Thanks!
