Maybe Tracy can figure it out from just the renderer code, but I think I need a complete (but small) test case with some sample data.
The only thing I see that looks unusual (besides calling refrehs() is setting both selectedItem and selectedIndex. One should be good enough.

Adding this refresh() statement was a way to force that to happen -- the user clicks on the combo box, the refresh happens (forcing the box closed), then the second click opens the drop-down with the proper data...

Here's my code as it stands right now.
