The docs say that @CollectionOfElements replaces @OneToMany. @OneToMany has a "cascade" attribute, but @CollectionOfElements does not. Does this mean that save and other operations have to be "manually" performed on the items in a collection mapped by @CollectionOfElements? I get a TransientObjectException when I try the simple test below. Note the "Cascading children with null" message in the log.
If, however, I add a "session.save(child);" line before "session.save(parent)" below, then everything seems to be written to the database correctly.
What do I need to do to get cascading of saves to work for @CollectionOfElements?
Hibernate version: 3.1.1, Annotation 3.1beta8
Mapping documents:
Code:
@Entity
public class Parent
{
@Id
@GeneratedValue
private Long id;
@CollectionOfElements
@MapKey
private Map<String, Child> children = new HashMap<String, Child>();
public Parent() {}
public void addChild(Child child)
{
this.children.put("" + System.currentTimeMillis(), child);
}
}
Code:
@Entity
public class Child
{
@Id
@GeneratedValue
private Long id;
public Child() {}
}
Code between sessionFactory.openSession() and session.close():(before opening session)
Code:
Parent parent = new Parent();
Child child = new Child();
parent.addChild(child);
(then)
Code:
Transaction tx = session.beginTransaction();
session.save(parent);
tx.commit();
Full stack trace of any exception that occurs:Code:
