Hi, all. We get this exception on commit when saving an entity (Entity A). We've verified the session/transaction are still open so it's not a LazyInit that you get when the session is no longer available.

This is on 1.2GA w/ SQL2000. Every entity has a proxy defined (same class w/ virtuals pattern). Entity A has a many-to-one to B (cascade=none). B has parent-child relationship to self (think tree). i.e. B has many-to-one to B ("Parent", cascade=none) and has one-to-many to B ("Children", cascade=save-update, inverse=true, lazy=true).

We've been debugging through it and it looks like the null ref exception is occuring because CollectionEntry.LoadedPersister is null. I cannot figure out what I'm doing wrong to cause it though. Thanks in advance for any help.

Cheers,
~Mork
