it looks like the number of pk-fields and the number of columns in the indirection table pointing to the m-side class are not the same.
could you please send me the testcase ?

Hi Edson,
I have the same problem here is my stack trace

seems the both are the same. I implemented a test case for the problem, but I'm currently working on the auto-xxx stuff so I can't send much time for that - put this on my imaginary todo-list for 1.0 ;-)
regards, Armin

This bug is driving me crazy... Someone could point me what changed from rc5
to 1.0 in this method (so I can at least fix locally)?
The problem is a M:N mapping using composite pk pointing the M bean, and 1
field pk pointing to the N bean.
The stack trace is:
