I am trying to load a unitCoverages (see below) collection lazily from a Unit persistent class and although it seems like all the queries are running fine etc...etc.., my objects are not being loaded. This is driving me insane. If anyone can spot the issue please let me know. All relevant code is belos

Code between sessionFactory.openSession() and session.close():

UnitPK pk = new UnitPK();
pk.setReferenceNumber(new Integer(600100));
pk.setUnitNumber(new Integer(1));
Unit un = (Unit) as400Session.load(Unit.class,pk);

//Unit has a set called unitCoverages which is not being loaded although in the mapping doc it is set for non-lazy load

//commit session
/close session....

So when you say that unit coverages isn't loaded do you mean you get a lazy init error when you try to access the set or that it comes back empty? If you get a lazy init then something is amiss, if you get nothing back then maybe your relationship (and or data) is flawed.

The set is empty so according to your train of thought, the relationship and/or data is flawed. The problem is that I am sure there is data in the relationship. So what other flaw in the data could there be that is causing this to fail??

I am assuming that Hibernate is populating your properties via mutatators? Debug that to see when it gets called what Hibernate is passing in.

Also, show your object code, silly as it sounds there might be something that is amiss in there.

I found another thread that has exactly the same problem as I am encountering. If you are interested, you can find it here:

http://forum.hibernate.org/viewtopic.php?t=937838

Thanks

So, I take it your problem is resolved then, using the same solution....

Have you posted your java classes and/or debugged to see what those sets are being set to? I've seen issues where a setter was defined as

setX(Set x)
{
this.someOtherCollectionNotX = x;
}
