I added DropDownEditorButton to ButtonsRight of my cell editor. When I have my CellClick action set to default it works just fine and drops down my control. If I set CellClick action to CellSelect I can still see drop down button in my cell but it no longer responds to my mouse clicks. I have other cells where I added ValueLists and these cells work correctly (they drop down their lists) even when CellClick is set to CellSelect. 

Why does DropDownEditorButton behaves differently from simple ValueLists? Bug? How do I make my DropDownEditorButton drop down in CellSelect mode?

Thanks,
