[hibernate-issues] [Hibernate-JIRA] Closed: (EJB-303) Removing an entity and clearing the persistence context messes up FlushMode.AUTO

Removing an entity and clearing the persistence context messes up FlushMode.AUTO -------------------------------------------------------------------------------- Key: EJB-303 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-303 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.0.ga Reporter: Geoffrey De Smet Priority: Critical Remove an entity, then EM.clear() before EM.flush() with FlushMode.AUTO makes next querty still contain the removed entity. Try something like this: public void delete(Person detachedPerson) { int oldSize = entityManager.createQuery("select x from Person person").getResultList().size(); Person person = entityManager.merge(detachedPerson); entityManager.remove(person); entityManager.clear(); // causes the problem entityManager.flush(); // probably obsolete to prove this bug int newSize = entityManager.createQuery("select x from Person person").getResultList().size(); assertEquals(newSize, oldSize - 1); // they turn out to be still the same size } Not doing entityManager.clear() fixes the problem, but because I am not using an extended peristence context and my testcases run in a rollback transaction, I need to clear the entityManger after every service call (so between the service call delete and the service call findAll). I looked through the JIRA's, but it didn't look like it's already posted.
