Who do I have to bribe to get this put into a release? (coughserious)

Trying to bind a collection to a joined-subclass and it's looking for the key column in the joined table, not the parent one. I'm assuming the patch won't be any good as it's kinda backwards.

To any other poor soul trying to figure this out, you're really only left with using a single table mapping with a discriminator, almost every other scenario is completely broken.
