But if there's a distinction between undefined and "zero" or 
"initial" then the UI should also provide a method to return a 
single control to that value. We have the same issue with radio 
button groups where it's possible to have none selected at the start 
but UI has no method to restore that state once one of the radio 
button controls has been toggled.

I think that every control should have some defined value always 
(even if that value *means* undefined) and UI should allow user to 
return a control to that state even after there was some other value 
in between.
