Folks I apologize for the repost, but it seems that whenever you follow the rules and post to this forum as the moderators require, I hardly ever get any responses.

I am trying to lazily load a set and although all the queries run and all the objects are hydrated according to the log, I cannot see my objects inside the Set. What I have is a class Unit which has a Set and the set should contain the type Coverage. One to many. Lazy is set to false, and even though all the queries execute and it seems like the Coverage objects are being created, whenever I inspect the Set property in Unit, it doesn't have anything. I am 100% sure that there are records in the database for the particular Unit I am loading. I have never had this issue and it is driving me insane. All relevant files are below:

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

The unitCoverages Set in Unit does not have anything in it.

*sigh*, see your 'other' thread for my reply. PITA with the double posting.

For the record, I don't see where this has anything to do with lazy loading either since lazy="false".

You're right, instead of lazy I should have called it eager.
