Hi!
I'm having problems with a collecction of composite-id objects.
To symplify things, I have created this 3 simple classes.
Prueba1 is a simple class with a normal id and a collection of Prueba2(pruebas2).
Prueba2 has a Prueba1 property (prueba1) and a composite id (prueba1, codigo). It also has a collection of Prueba3 (pruebas3)
Prueba3 has a Prueba2 property (prueba2) and a composite id (prueba1, codigo).
All of this classes have a property called hibVersion for use with the version mapping.

Since Prueba2 is composite-id entity, in order to load it using Session.get(Class, Serializable) I have to create an instance of Prueba2 to use as Id, but before I have to load the Prueba1 object that is part of the id. Because of the architecture of my application, I do this in two separate sessions. I create a session, load the Prueba1 entity, close the session, then I open another session and I attempt to load the Prueba2 entity.

The Prueba2 entity is loaded fine, but the collection of Prueba3(pruebas3) object is empty when it should have at least one object.

If I do all this in a single session, the collection is loaded just fine.

I've seen a couple of posts that had problems with equals() or hashCode() but I don't think that's the problem here.

If anyone can give me a clue as to why this doesn't work in two sessions (its seems to me it shouldn't be an issue) I'd be very gratefull.

Thanks in advance,
JJ

Code between sessionFactory.openSession() and session.close():
This is not the actual code of my application :)
Its a very simplified version designed to isolate the problem.
Code:
   Session sesion = HibernateUtil.currentSession();
   Transaction tx = sesion.beginTransaction();
   Prueba1 p1 = (Prueba1)sesion.get( Prueba1.class, new Integer(1) );
   tx.commit();
   HibernateUtil.closeSession();
   sesion = HibernateUtil.currentSession();
   tx = sesion.beginTransaction();
   Prueba2 p2 = new Prueba2();
   p2.setPrueba1( p1 );
   p2.setCodigo( 10 );
   p2 = (Prueba2)sesion.get( Prueba2.class, p2 );
   tx.commit();
   HibernateUtil.closeSession();


If I comment lines 5 to 7 it works just fine.

I've encountered the same problem with a different set of classes in my aplication.
The problem seems to be more simple than I had originaly thought:
When loading a entity with a composite id ( many-to-one, property ) and a one-to-many, inverse=true, bag using a transient instance in the many-to-one relationship, Hibernate does NOT load the collection.
I'm thinking of posting this to JIRA if no one objects...

Look at this from my previous post:
Quote:
17:54:56,125 DEBUG Printer:82 - pruebas.Prueba2{hibVersion=0, pruebas3=[]}
17:54:56,125 DEBUG Printer:82 - pruebas.Prueba2{hibVersion=0, pruebas3=[Prueba3]}


Why are there 2 instances of the same object?

Why are there 2 instances of the same object?

I can only assume both of these are equals() hashcode() issues. The code above has complex equals() implementations, which I cannot claim to understand. Hard to me to distinguish between classes named Preuba1, Preuba2, Preuba3.

I would suggest both of you put some logging in your equals() implementations and confirm they are working properly in all cases.

...better yet, create some unit tests. Equals has caused me problems more than once, so it is crucial to cover.
