Hi Peter,

didn't know about that one. It basically does what Tom suggested: makes 
a copy, sorts that one, then uses ObservableList.setAll to get one 
change event. So it is what I am doing already but still removes/adds 
children ;-)  The remove/add approach also does work for now, it just 
could be a little more efficent...
