What steps will reproduce the problem?
This detached entity won't save to the datastore after merge. I've tried dozens
of tricks with no luck. Is the solution JDO or raw Datastore API? It just won't
save, no matter how long I wait.
EntityManager em = EMF.get().createEntityManager();
em.getTransaction().begin();
OnixUser s = admin.get(0);
if (s.id == null) {
em.persist(s);
em.getTransaction().commit();
}
else {
log.info("email:" + s.email + ", isAdmin:" + s.isAdmin + ", id:" + s.id + ", state:" + NucleusJPAHelper.getObjectState(s));
OnixUser merged = em.merge(s);
log.info("merged... email:" + merged.email + ", isAdmin:" + merged.isAdmin + ", id:" + merged.id + ", state:" + NucleusJPAHelper.getObjectState(merged));
em.persist(merged); //// TRIED WITH & WITHOUT PERSIST
log.info("persisted... email:" + merged.email + ", isAdmin:" + merged.isAdmin + ", id:" + merged.id + ", state:" + NucleusJPAHelper.getObjectState(merged));
em.flush();
log.info("flushed... email:" + merged.email + ", isAdmin:" + merged.isAdmin + ", id:" + merged.id + ", state:" + NucleusJPAHelper.getObjectState(merged));
em.getTransaction().commit();
em.refresh(merged);
/////// THIS IS WHERE IT FAILS isAdmin reverts back to 0.
log.info("refreshed... email:" + merged.email + ", isAdmin:" + merged.isAdmin + ", id:" + merged.id + ", state:" + NucleusJPAHelper.getObjectState(merged));
}
em.close();

What is the expected output? What do you see instead?
Expected to see isAdmin changed to 1 in the AppEngine admin interface for the
entity. Expect to see isAdmin = 1 after em.refresh().
