========= Child objects are loaded from the datastore when they are accessed for the first time. If you do not access the child object on a parent object, the entity for the child object is never loaded. (The datastore interface does not support the "eager" loading of child objects. The datastore does not support join queries, so an implementation of eager loading wouldn't save the app a call to the datastore.) ========= But it works only if the parent is attached to PersistentManager (before pm.close). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
