Hi Paul, from its name "model.User", it seems that your class is an inner class: I had problems with JDO in the past because of inner classes. I could not get good explanations about what's possible with inner classes and jdo or not.
As a consequence, I don't try to persist inner classes with JDO anymore Can you try to make your class a regular one and see what happens? regards didier On Oct 19, 10:01 am, Paul <pgronkiew...@gmail.com> wrote: > Hi, > > I suddenly started getting that error and I have no idea why.
