Hi, I'm wondering if two attached/managed entities obtained from the same persistence context in two different ways are guaranteed to be equal by referential identity? For example: Let A and B be related. | A a = (A)em.find(...); | B b = (B)em.find(B.class, a.getB().getId()); | | assert(b.equals(a.getB()); | assert(b == a.getB()); | The above example works on JBoss EJB3 RC9 i.e. Hibernate, but is it guaranteed by the specification? I could'nt find any clear statement about it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006762#...
