For drop-down/drop-down-list combo-box when the drop down list is made visible and a value is selected before closing it the value-changed event always fire and modified is set to true, even if the same item as before was selected - in FWD if the selection does not change the event isn't fired and modified remains false as a result.

The changed event in ListSelectionModel isn't fired if the same item was selected. Since that is used basically by the selection-list widget the code looks alright in that respect - for selection-list when one click on the same item so selection does not change the value-changed even isn't fired - the code needs to take into consideration the combo-box use-case (a listener that needs to be notified even if new selection is the same as current one).
