4. Simpler way of specifying what collections to initialize    forum.hibernate.org

I thought of a simpler way to specify what parts of a class that should be loaded, or actually, which set/bag/.. (Collection type) properties that should be initialized. Eg, I thought of something like this. If you have class Owner { Set cats; Set friends; Set hobbies; } then Session.load(Owner.class, id, "cats", "friends") would load the Owner with it's set of ...

8. could not initialize collection    forum.hibernate.org

I am getting exception "could not initialize collection" after a criteria query that looks like it is working correctly. I suspect it has something to do with the inclusion of an "extra" field in an association table in a composite-element, as I'm not sure what kinds of objects are being stored my "java.util.Set" (I'm hoping StatementItem objects). Hibernate version: 2.1.6 Mapping ...

16. Initialize collections using AliasToBeanResultTransformer    forum.hibernate.org

Hi I'm running a HQL query and using an AliasToBeanResultTransformer to create bean instances. Child collections are not initialized by that transformer, I believe this is "as designed".

Reloading (session.refresh()) each object seems stupid, as I've just accessed all required data using the query, so running a SELECT for each ...
