Suggest a PlaceController Enhancement with the Delegate overriding

I'd like to suggest a PlaceController Enhancement with the Delegate overriding so I can have the place controller check if the warning has been cleared.

I'd like to build my own popup dialog as the delegate which is non blocking, and goto the newPlace when my saving data is done, instead of asking for the person to cancel an go do the saving manually. Basically, I'd like to tell the Place Controller via event that its ok now, or easier would be to say, check the warning message again, b/c it should be cleared. 

Currently the confirmation dialog is blocking and returns boolean in the place controller and I'd like to control the maybeGotoPlace with events. 

Thoughts?

public class PlaceController {
//...
  public void goTo(Place newPlace) {
    log().fine("goTo: " + newPlace);

    if (getWhere().equals(newPlace)) {
      log().fine("Asked to return to the same place: " + newPlace);
      return;
    }

    // NOTE: delegate.confirm(warning) is blocking until dialog comes back true|false
    String warning = maybeGoTo(newPlace);
    if (warning == null || delegate.confirm(warning)) {
      where = newPlace;
      eventBus.fireEvent(new PlaceChangeEvent(newPlace));
    }
  }
//...
}
