If you are using a serialized field you must add the serialized="true" clause to your annotation
@Persistent(serialized="true") MySerializableObject serializable; Also notice that JDO does not automatically detect if you update only the inner fields of the object you save, so you must substitute it with a copy to have it persisted. See this post for a very good overview and an explanation of the fact above: http://groups.google.com/group/google-appengine-java/browse_thread/thread/747ceed8396c0ed8/b311227fbe4d9304?lnk=gst&q=serialized+fields+snippets+work#b311227fbe4d9304 Regards Lorenzo On Jul 7, 1:33 am, laserjim <laser...@gmail.com> wrote: > Hello, > > I'm still trying to persist a list of serializable objects.
