  spring hibernate gwt requestfactory
  I’m using GWT RequestFactory + Hibernate + Spring in my web app. I have Principal and Profile entities that relate to each other as one to one. They share the same primary key. On a client side I write such a code, which causes NullPointerException:If I exclude “principal.setProfile(profile);” code line, principal entity will be stored successfully. I can’t figure out why profile entity can’t be stored along with principal.Any suggestions will be highly appreciated. Thanks in advance!public Re

  google-app-engine gwt requestfactory
  I have a problem using “fire()” with a GWT RequestFactory after I’ve used it to unfreeze and edit a proxy.If I have two request factory objects and their associated contexts like this: private SyntheticRequest req1 = requestFactory.someRequest(); private Request<xProxy> sendRequest1 = req1.something(); private SyntheticRequest req2 = requestFactory.someRequest(); private Request<xProxy> sendRequest2 = req2.something();using “fire()” on the first request works fine:sendRequest1.fire

  java gwt requestfactory requestcontext
  I’m trying to integrate GWT and Hibernate using RequestFactory. Everything works well, except when I try to work with an existing entity. It doesn’t matter what I’m trying to do (load, update or delete), the result is always the same: NullPointerException.After some debugging, I realized that when the request is fired, a JsonSplittable that contains only a string with the ID of my existing entity (“1”, for instance) is processed as if it had a JSONObject. The method getOrReify is executed and th

  java gwt gwt2 requestfactory
  I am using GWT 2.4 with the editor and request factory frameworks. I have a model, Trip, which has an Address ‘origin’ and an Address ‘destination’. When creating a Trip via the UI, the two addresses are created automatically and assigned to the Trip. User fills out details and saves. For some reason, I am getting the ‘autobean frozen error’ when trying to persist to the server. This code worked in GWT 2.3 and I cant switch back. I am hoping its not a bug in GWT 2.4. Here is some sample code of

  gwt requestfactory
  Cannot validate this method because the domain mapping for the return type (XXXProxy) could not be resolved to a domain type Add @SuppressWarnings(“requestfactory”) to dismiss.Starting with GWT 2.4, RequestFactory interfaces must be validated before they can be used by the RequestFactory server code or JVM-based clients. This document explains the mechanisms for validating those interfaces. according to http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidationI have do
