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();
