AsyncProxy and ActivityMapper

Hi All, 

I am trying to get the code splitting working on the ActivityMapper. 

I have taken the MVP tutorial sample (http://code.google.com/webtoolkit/doc/latest/DevGuideMvpActivitiesAndPlaces.html) and converted that to use GIN.

After reading a number of posts on the group decided to implement ActivityAsyncProxy (following example from here:  http://code.google.com/p/google-web-toolkit/issues/detail?id=5129 )

and AsyncGoodbyeActivityProvider. Below are the listings for some of the code: 

public class AppActivityMapper implements ActivityMapper {

public AppActivityMapper() {

super();

}

ActivityAsyncProxy<GoodbyeActivity> goodbyeActivityProxy = new ActivityAsyncProxy<GoodbyeActivity>(Ginjector.INSTANCE.getAsyncGoodbyeActivityProvider());

@Override

public Activity getActivity(final Place place) {

Activity activity = null;

if (place instanceof HelloPlace) {

final HelloActivity.Factory factory = Ginjector.INSTANCE.getHelloActivityFactory();

activity = factory.get((HelloPlace) place);

}

else if (place instanceof GoodbyePlace) {

activity = goodbyeActivityProxy;

}

return activity;

}

}

And Ginjector

@GinModules({GinModule.class})

public interface Ginjector extends com.google.gwt.inject.client.Ginjector {

static final Ginjector INSTANCE = GWT.create(Ginjector.class);

EventBus getEventBus();

HelloView getHelloView();

GoodbyeView getGoodbyeView();

PlaceController getPlaceController();

HelloActivity.Factory getHelloActivityFactory();

HelloPlace.Factory getHelloPlaceFactory();

GoodbyeActivity.Factory getGoodbyeActivityFactory();

GoodbyePlace.Factory getGoodbyePlaceFactory();

AsyncProvider<GoodbyeActivity> getAsyncGoodbyeActivityProvider();

}

public class GinModule extends AbstractGinModule {

@Override

protected void configure() {

bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);

bind(HelloView.class).to(HelloViewImpl.class).in(Singleton.class);

bind(GoodbyeView.class).to(GoodbyeViewImpl.class).in(Singleton.class);

bind(PlaceController.class).to(AppPlaceController.class).in(Singleton.class);

bind(new TypeLiteral<AsyncProvider<GoodbyeActivity>>() {}).to(AsyncGoodbyeActivityProvider.class);

install(new GinFactoryModuleBuilder().build(HelloActivity.Factory.class));

install(new GinFactoryModuleBuilder().build(HelloPlace.Factory.class));

install(new GinFactoryModuleBuilder().build(GoodbyeActivity.Factory.class));

install(new GinFactoryModuleBuilder().build(GoodbyePlace.Factory.class));

}

}

public class AsyncGoodbyeActivityProvider implements AsyncProvider<GoodbyeActivity> {

public void get(AsyncCallback<GoodbyeActivity> asyncCallback) {

GoodbyePlace place = new GoodbyePlace("Frank");

asyncCallback.onSuccess(Ginjector.INSTANCE.getGoodbyeActivityFactory().get(place));

}

}

All that works fine with AsyncGoodbyeActivityProvider being bound in GIN. 

However, what I want to achieve is to use AsyncProxy in AppActivityMapper . I read number of samples and couldn't find the approach that I can use with GIN. 

Could anyone recommend the solution?  

How can I use the AsyncProxy instead of writing own ActivityAsyncProxy? 

Thanks,

Kris
