Johannes,
Is it possible that you used Cayenne 1.0.7 before (the latest stable
release of 1.0 cycle)?
EVen if not it is worth trying to upgrade to 1.0.7, if you are not ready
to go all the way to 1.1. 1.0.7 shouldn't have any compatibility issues
with 1.0 and it contains a number of object graph manipulation bug fixes.
