GWT：如何从Activity start方法中转到新位置？

Question

So I'm doing something like this:

public class SecureActivity extends AbstractActivity {
  public void start(AcceptsOneWidget container, EventBus eventBus) {    
    if (!_app.isUserLoggedIn()) {
      _app.goTo(new LoginPlace(_app.getCurrentPlaceToken()))
    } else {
      // do cool secure stuff
    }
  }
}

But the behavior that I'm seeing is that my browser's history is for original url (from the original request), then the login:redirectPlace, and then original url again.

It seems like I need to do my redirection after the start() method has completed. Is there a proper way to delay/delegate that goTo to happen outside of the start method?

Thanks.

That should be enough:

Scheduler.get().scheduleFinally(new ScheduledCommand() {
   @Override
   public void execute() {
      _app.goTo(new LoginPlace(_app.getCurrentPlaceToken());
   }
}
