In my own testing, I have this working for owned one-to-one relationships, although there are issues with owned one-to-many relationships of the same kind -- no exceptions are thrown but entities of the kind in question don't appear to be persisted. We're exploring this further internally, but please file a bug report in the public issue tracker for the DataNucleus plugin: http://code.google.com/p/datanucleus-appengine/issues/list
