    Hi,

    Sorry, you posted this earlier and looks like nobody replied yet.

    No, it is not normal. I just created a test case to reproduce it and
    things seem to be working ok:

         PaintingInfo info = ctxt.newObject(PaintingInfo.class);
         info.setTextReview("XXX");
         p1.setToPaintingInfo(info);

         assertSame(info, p1.getToPaintingInfo());
         ctxt.rollbackChanges();
         assertNull(p1.getToPaintingInfo());

    Does it look like the scenario that you have, or am I missing something?

    Thanks,
    Andrus
