Hello friends.

The log says Deferred binding result type '

This happens when I change the imported packages of import
com.google.gwt.event.shared.EventBus;
com.google.gwt.event.shared.SimpleEventBus import, to import
com.google.web.bindery.event.shared.EventBus;
import com.google.web.bindery.event.shared.SimpleEventBus;.
I made this change because the constructor of the class PlaceController
is deprecated
@ Deprecated
public PlaceController (com.google.gwt.event.shared.EventBus eventBus)
{
this ((EventBus) eventBus);
}
Any idea how to solve it?
Thanks and greetings!

HI Thomas. Thanks for the quick response.

Re: PlaceController constructor Deprecated
HI Thomas. In my code, I have a class that extends AbstractActivity. The problem is that the interface Activity, which has the method void start (AcceptsOneWidget panel, EventBus eventBus). EventBus belongs to the packagecom.google.gwt.event.shared and should be the com.google.web.bindery.event.shared Is this a mistake? regards 2011/9/9 Fabricio Pizzichillo fpizzichi...@gmail.com HI Thomas.

Re: PlaceController constructor Deprecated
Maybe [1], but that's not relevant to your issue: start() is not called by GIN but by an ActivityManager. That one has a dependency on some EventBus, but the web.bindery one, so it's not the guilty party either. [1] Changing the type of the argument from the com.google.gwt.… EventBus to its parent in web.bindery would have broken everyone's activities, because Java only supports covariance for return types (see http://en.wikipedia.org/wiki/Covariance_and_contravariance_(computer_science)#Java ) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
