Here's some things to look at. versionumber must be 0 when you fetch it, are you sure there is only one instance of ManifestVersion, and if there is supposed to be only one, why the call to ManifestVersion.all(), you should just get the object by id or key. (Have you confirmed that there is only one instance returned from all () ?) my guess is you have more than one instance

On the other hand num is changed in this call. > What am I doing wrong? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
