[castor-user] JDO: Serious problem

Wed, 29 Jun 2005 11:18:02 -0700 

am getting the exception below. I have no idea why it's happening? I
can create the object no problem and have even successfully updated once, but not after that? Much help is appreciated. I was using 0.9.6 and upgraded to 0.9.7 no difference. 
I tried including the files however the mail server doesn't accept messages > 
30000 bytes.  However I can send them in smaller
chunks if someone wants to help me.


Exception (using 0.9.7):
