Let me put this another way.

The point of a combobox is to allow the user to
make a choice that the programmer didn't anticipate.
If the programmer *had* anticipated it, he would have
included it on the list of possible choices.

If you, as the programmer, want to make an unanticipated
choice for the user, then you are following the principles
of Thinking For You, which we have already decided earlier
this week is NOT the IDL way. Hence, IDL makes it impossible
to make this program design error. :-)

Cheers,

David
