I believe the exception you're getting is the result of having multiple parents for the same type, and unfortunately that bug isn't fixed in this release. The bugs fixed in this release are:
- Incorrect exception for multiple fields of same type http://code.google.com/p/datanucleus-appengine/issues/detail?id=172 - Non-persistent base classes do not work http://code.google.com/p/datanucleus-appengine/issues/detail?id=169 - Relationships in abstract base classes don't work http://code.google.com/p/datanucleus-appengine/issues/detail?id=171 On Sat, Dec 12, 2009 at 1:09 AM, bryce cottam <bcot...@gmail.com> wrote: > hmmm....
