FWD » Core Development » User Interface

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).

Seems, this issue does not exist anymore (trunk rev. 15969).

Marian, can you confirm this, or create a demo example proving this issue still exists?

Vladimir, it's been a while since we've tested anything in FWD and currently we're not actively involved in the project so I can't really confirm anything. However, there might be tests for VALUE-CHANGED that could help in testcases - look into tests/ui_tests/combo_box folder. Although this has more to do with the event handling so maybe something in the interactive sub-folder, not sure if this exact scenario is being simulated though.
