Body:
whoa! Thats bad....
But I'm looking at the code and I just don't see how it could occur!
Can you please submit a main() method to reproduce this? It doesn't occur in tests and the code certainly LOOKS correct. I'm stumped!
p.s. I suppose you are _absolutely_ certain you aren't hitting the session from multiple threads....

Body:
I'm not 100% sure, but 99%. I'll check again tomorrow and see if I can submit a test case to reproduce it. The strangest thing is that it works as expected using the 2.0.3 version, doing the exact same thing!

Author: Mathias Bogaert
Created: Thu, 4 Sep 2003 6:32 AM
Body:
After verifying it, I'm _certain_ I'm not accessing it from different threads. It has something to do with the object that is removed from the hashmap (and that is in the collection being initialized) already was loaded by the session before. I'll continue trying to reproduce in a testcase.

Tried again with the latest Hibernate 2.1 (CVS from yesterday) and I'm unable to reproduce the problem. So it seems to have resolved itself!
