I've been facing the same kind of problem ; my program keeps complaining
about "unmanaged object" despite using EntityManager.getReference() as
suggested by Patrick. I wonder what I've been doing wrong. Would you show
the piece of code (and possibly the related configuration part in orm.xml)
that made your program run ?
This is really an old thread. :)
Something like:
em.getTransaction().begin();
Child c = new Child();
c.setName("Bob");
c.setParent(em.getReference(Parent.class, 123););
em.persist(predmet);
em.getTransaction().commit();
should work. More or less, thats what I'm doing. Maybe you could post
your code, and exact stack trace?
