How to exclude a property when using the RequestFactory in GWT

I'am using the RequestFactory to retrieve a list of objects from the server. Now I want to exclude the "description" (String) property of the object which can contains a long text.

Is there any way to do that in RequestFactory at Runtime?

This is how I retrieve the list

    collectcontextProvider.get().getListObject().fire(
    new Receiver<List<ObjectProxy>>() {
    @Override
    public void onSuccess (List<ObjectProxy> objectList) {
        //display the list
        }           

        @Override
        public void onFailure(ServerFailure error) {
            //Error
          }
        });

I use Hibernate

Assuming you want the description field in other places of your app, you'll want a trimmed-down proxy that does not expose that property, and of course a service method that returns a list of such proxies.

@ProxyFor(value=MyObject.class, locator=MyLocator.class)
interface MyObjectLiteProxy extends EntityProxy {
   // all properties but 'description'
}

@ProxyFor(value=MyObject.class, locator=MyLocator.class)
interface MyObjectProxy extend MyObjectLiteProxy {
   String getDescription();
}

@Service(MyService.class)
interface CollectContext extends RequestContext {
   Request<List<MyObjectLiteProxy>> getListObjectLite();

   Request<List<MyObjectProxy>> getListObject();
}

Actually, you could even go farther and use the same MyService implementation for 2 RequestContexts:

@Service(MyService.class)
interface CollectLiteContext extends RequestContext {
   Request<List<MyObjectLiteProxy>> getListObject();
}

@Service(MyService.class)
interface CollectContext extends RequestContext {
   Request<List<MyObjectProxy>> getListObject();
}
