Subject Re: Object Validation Auto Increment Problem
Date Fri, 19 Jun 2009 11:23:46 GMT
You can't uncheck mandatory checkbox for a PK.

As to the original problem, I am pretty sure I am not seeing this  
behavior in Cayenne 3.0. Could be a bug in 2.0.4. Would it be possible  
to try it out with 3.0?
