Steve Ebersole commented on HHH-2112:
-------------------------------------

Cool, you've isolated the cause so it should be trivial to come up with a small test case.

I mean if the issue is really just the "red herring"-ness, I can easily come up with a more appropriate failure message.

If you want to argue that this should be allowed, I need a test case showing what it is that you are trying to do and believe to be valid.  And given your description, it should be easy to come up with an example that uses one or two domain objects.

> In these situations, this method should probably return null. It is very likely since other calling methods check for the returned value to be null .
