ComboBox: TestEditor to ListView binding

Hi Kirill,

What exactly are you trying to do?  The following (crap) listens for the 
value to change and then sets it back:

         ChangeListener<String> l = new ChangeListener<String> () {
             public void changed(ObservableValue observable, String 
                     String newValue) {
                 System.out.println("attempt to set new value: " + 
                 Platform.runLater(() -> {
                     System.out.println("restoring old value: " + newValue);

This is not good code because it adds and removes a listener to avoid 
notification when the value is reset.  It uses runLater() in order to 
stop the combo box from getting confused when the value is changed from 
within a changed listener.
