Are you positive that the UserProfile instance isn't getting stored or just isn't getting returned when you later query for the UserPrincipalCredentials object? You can verify this using the local datastore viewer -- just go to http://localhost:8080/_ah/admin when your local dev server is running.
My guess is that the UserProfile entity is being saved but it's not being fetched so you see null when you try to access it. Try adding it to the default fetch group like so: @Persistent(defaultFetchGroup = "true") private UserProfile userProfile; // ... Let me know if that helps. - Jason On Mon, Jan 11, 2010 at 1:24 AM, Kamlesh <[email protected]> wrote: > When ever I try to save object of class UserPrincipalCredentials , > using persistancemanager (see snippet below) , the child property > userProfile does not get saved. can anyone please review my > annotations and tell me what could be wrong with them ? > > Code for saving Operation > ________________________________________________ > public UserPrincipalCredentials create(UserPrincipalCredentials > credentials) { > final PersistenceManager pm = > PMFProvider.get().getPersistenceManager > (); > try { > System.out.println("trying to save"); > //final UserProfile profile = > credentials.getUserProfile(); > //profile.setLoginAccount(credentials); > pm.makePersistent(credentials); > > } finally { > pm.close(); > } > > System.out.println("New User Added.......
