    Problems with @Inject annotation

    Rene Lenno Newbie

      Hi,

       

      I'm trying to use Errai in my GWT project. I'm a total newbie, so my question may be trivial but I really can't figure it out:

       

      I have a GWT Project that is designed according to the MVP GWT example:

      http://code.google.com/intl/en-US/webtoolkit/articles/mvp-architecture.html

       

      I'm trying to replace the server-client communication bei Errai. The problem I have is that the Incetion only seems to work. On the @EntryPoint:

       

      @EntryPoint

      public class App {

       

          @Inject

          private Event<UserCustomRequest> userCustomRequest;

       

          @PostConstruct

          public void onModuleLoad() {

              new AppController(this).go(RootPanel.get());

          }

       

          public void response(@Observes UserCustomResponse event) {

               Window.alert("response");

          }

          [...]

      }

       

      This works fine, but if i try to use the @Inject annotation for my requests or responeses in other classes than the @EntryPoint, the injection seems to fail (in this case, userCustomRequest is null). Also the response method isn't called in any other class than the @EntryPoint class:

       

      public class AnyPresenter implements Presenter {

           @Inject

           private Event<UserCustomRequest> userCustomRequest;

       

           public void response(@Observes UserCustomResponse event) {

                Window.alert("response");

           }

           [...]

      }

       

       

      Thanks for the help!
