Given that renderers recycle, if you have a ComboBox in a renderer, you usually need to store its selectedIndex somewhere (in the data, on the column, in some map). If you're calculating it on the fly, that might slow scrolling so you should consider storing it somewhere.

The dataField for that column says "2", the ItemRenderer uses a labelFunction to reach in to a different ArrayCollection and pull out a meaningful name, "Foo". The DataGrid is sorted by the arrayCollection so the original index value of the selectedItem in the DataProvider doesn't do me much good. I guess I could pass the ArrayCollection to the popup and have it duplicate the same labelFunction I jsut thought there might be a way to ask the ItemRenderer for the DataGrid's column for the SelectedIndex (in the renderer, not the DataGrid).

If not, ArrayCollection has getItemIndex().
