I'm porting my code to the new b20 / Property release and run into this:

1. I have 42 ToggleButtons
2. To each I register the same ChangeListener (instead of 42 separate)
3. Inside the ChangeListener I want to find out which toggle button was the origin of the event

class {
   private void x() {
           ToggleButton lToggleButton = new ToggleButton();
           lToggleButton.selectedModel().addChangeListener(iDayToggleButtonSelectedValueModelListener);
   }

   private ValueModelListener iDayToggleButtonSelectedValueModelListener = new ValueModelListener() {
       @Override
       public void handle(ObservableValue observableValue) {
           BooleanProperty lBooleanProperty = (BooleanProperty)observableValue;
       }
}

My problems are:
- I have to cast the ObservableValue to BooleanProperty to be able to access the value, that can't be right?!
- There is no way I can find what ToggleButton was clicked?

I would expect the addChangeListener to be generic;
   ...addChangeListener(ValueModelListener<BooleanProperty> ...)

I would expect the ValueModelListener use its generics:
   public void handle(BooleanProperty observableValue)
