The roadmap for 3.1 says: .
While this will be useful*, our application would actually benefit more from the ability to specify order-by and fetch-strategy on sub-criteria.

Is this planned for the 3.1 "other new features"?

I noticed that explicit code has been added to the Hibernate 3 codebase to throw a specific exception when the user tries to add an order-by to a sub-criteria.

How hard would it be to extend the Criteria API to support ordering and such on sub-criteria? Is there some kind of fundamental issue, or does it just need someone to get around to it?

* Depending of course on how the Criteria API will actually support this. Has a way forward been decided upn yet for how to specify projection?

The fundamental issue is that no-one has time to work on this stuff until after 3.0 is out.

There's already a patch, see HB-132 (assuming the patch works).

Is there a plan to apply this patch to the codebase?
