void onChanged(ChangedEvent event)
 Change/Changed notifications vs "...When" rules: the change and
 changed events only fire when an end user modifies a field value.  If you are trying to dynamically control
 the visibility or enabled state of other  components in response to these events, consider instead using properties 
 such as Canvas.visibleWhen, item.readOnlyWhen, Canvas.enableWhen on the target component. (Similar properties are 
 available on FormItem, Canvas,
 MenuItem and other components).
