ComboBox: TestEditor to ListView binding

[Stephen F Northover]

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 
oldValue,
                     String newValue) {
                 System.out.println("attempt to set new value: " + 
newValue);
                 Platform.runLater(() -> {
                     comboBox3.valueProperty().removeListener(this);
                     System.out.println("restoring old value: " + newValue);
                     comboBox3.setValue(oldValue);
                     comboBox3.valueProperty().addListener(this);
                 });
             };
         };
         comboBox3.valueProperty().addListener(l);

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.
