I think we need to see some code, like how the renderer is set up.  A combobox 
in a datagrid is a renderer so its data setter will fire setting the 
selectedItem to the item's dataField assigned to its column.  The question is 
why itemToLabel and the labelFunction didn't do its thing.

No, you shouldn't have to do anything like that.  Normal behavior for a combo 
box is to display nothing until a user interacts with it, selectedItem is null 
and selectedindex is -1.  If yours is doing something else then there is code 
doing it.  Is it a stock ComboBox?  It sounds like someone has overridden the 
internal text field.

Or ha, there is a prompt specified that is a code value.

I wish...no, I'm using labelField in one and a labelFunction in another one, 
but these are not invoked until you actually click on the dropdown. Thus, when 
data is first retrieved into the dropdown, the darned thing is displaying the 
"data" field rather than the "label: field. Should I be firing off something to 
force the dropdown to update when the data comes in?
