> An entity with a OneToMany property (cascade=all) is retrieved from the DB, then a NEW instance is added to the OneToMany property. If you call refresh on the parent it will give an assertion failure because Hibernate tries to refresh the added object although it is not persistent.
> eg:
> class Child { }
> class Parent {
> @OneToMany(cascade=ALL) List<Child> children;
> }
> Parent p = em.find(Parent.class, 1);
> p.children.add(new Child());
> em.refresh(p);
> This causes:
