Hi,
I have a 1:1 relationship between person and address. Person is the owner of the rel, contains the foreign key. When I refresh the address, I get an exception, see below for further details.
Any ideas?

Hibernate version:
Annotations: 3.2.0 CR1, 13.05.2006
Core: 3.2 cr2
EntityManager: 3.2.0.CR1, 13.05.2006

Code between sessionFactory.openSession() and session.close():

EntityManager em = emf.createEntityManager();
address.setPerson(person);
person.setHomeAddress(address);
em.persist(address);
em.persist(person);
em.getTransaction().begin();
em.getTransaction().commit();

em.clear();
em.merge(address);


Full stack trace of any exception that occurs:

I think it has been solved is subsequent versions. Try the latest of Hibernate core, annotations and entitymanager
