OK, what you put is exactly what I am doing, almost word for word. When i set my dataprovider to a new ArrayCollection - the first time it works fine, then after that it works but the new data does not appear in the combobox. All the bindings appear to fire, and the new data is in the backing ArrayCollection as seen from the debugger. However, on the screen the dropdown is now empty. Hence my thought that I somehow need to create or renew a binding between the combobox and the .mxml file (the screen) that it is nested in.
I appreciate your help.
