Hi, I'm trying to set the primary key in order to be able to read from DB the exact object faster. Looking at that tutorial http://code.google.com/appengine/docs/java/datastore/creatinggettinganddeletingdata.html this should be possible. Nevertheless all my attempts using Key k = KeyFactory.createKey(Unit.class.getSimpleName(), 11111); or guessing with any other variations I always receive:
javax.jdo.JDOFatalUserException: Attempt was made to manually set the id component of a Key primary key. If you want to control the value of the primary key, set the name component instead. What I'm doing wrong? Is it possible at all to set my own part of the primary key? What "set the name component" means? AFAIK the key contains appID, object kind and ID, there is no name as part of the key. Sorry if my question is stupid, but I'm just starting with GWT. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
