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. -- Mikko
