I am facing the situation as described in :

http://forums.hibernate.org/viewtopic.p ... fcedc553be

a child collection is loaded but is not attached to its parent (size = 0). It works when I use a Long as the parentId but as soon as I use a UserType, it doesn't work.

help !

Are you using Types.NUMERIC like tzman was? If you are, try Types.BIGINT instead. Longs map to BIGINTs, NUMERIC is for certain kinds of floating point numbers (though usually DECIMAL is a better choice).

I do use Types.BIGINT

I don't understand. The many-to-one seems perfectly but the one-to-many doesn't work with UserType.

Does anyone know a solution?

The problem maybe near Loader.readCollectionElement(). Currently, owner is null. As I understand it, the owner should be set to the parent?
