Making this ComboGrid based component editable allows implicit filtering the backing store. This is quite helpful on file selection, as for example the ISO file selector from the create wizard is. Clear the filter (and its displayed value) on store selection change, as there the filter becomes void - at least this is a simple and easy solution without glitches.
