Hello, this question is probably best answered by Michael Dick: Does this code expose/represent bug 1365, or it is something new?
public void testNonUnique() throws Exception { EntityA a1 = setup.insertA("1"); EntityB b1 = setup.insertB("1"); EntityB b2 = setup.insertB("2"); a1.getChildren().add(b1); a1.getChildren().add(b2); em.getTransaction().begin(); em.persist(a1); em.getTransaction().commit(); em.close(); em = emf.createEntityManager(); EntityA fresh1 = reload(a1); // OK try { EntityA fresh2 = reload(a1); // fail fail("Expected exception"); } catch (Exception exc) {} } private EntityA reload(EntityA original) { Query query = em.createQuery("select distinct o from EntityA as o" + " left join fetch o.children" + " where o.id = :id"); query.setParameter("id", original.getId()); return (EntityA) query.getSingleResult(); } -- Daryl Stultz _____________________________________ 6 Degrees Software and Consulting, Inc. http://www.6degrees.com mailto:da...@6degrees.com
