[flexcoders] itemEditor ComboBox values

[nathanpdaniel]

If I use a ComboBox as an itemEditor on a DataGrid, it sets the value 
in the grid to the "label" value of the item.  How do I get the value 
of something else?  (if combobox.labelField="this", I wanna use 
combobox.selectedItem.that for the value but still display the 
labelField)  Thanks!
