Dear group,
What is supposed to happen in this scenario:
@Entity
class Person {
//...
Address address; //cascade-merge or cascade-all are not specified
}
@Entity
class Address {
//...
}
em.getTransaction().begin();
Person p = new Person();
em.persist(p);
em.getTransaction().commit();
em.getTransaction().begin();
em.detach(p);
p.setAddress(new Address());
Person m_p = em.merge(p);
//what does m_p's "address" field contain? Or should merge throw an
exception right away?
Thank you!
Christian
