  The scope of this is actually a bit larger.  It boils down to whether we 
should allow the user to type anything in this field at all, or if the 
datasources should supply the contents exclusively.  0 is not the only 
invalid thing that can be entered in this field.  Are there any datasources 
that might not know their fields before reading the file or attempting to 
open a given field?

Still no response to my comments here.  I'm tempted to make this combo non-editable, though completable (if you understand what I mean).

Frame Files don't return a complete frame list, though no-one is using it now.
But others could come up.  How about if data-sources have a bool fieldListIsComplete() method to help us decide.
Editable if incomplete, non-editable if complete.

CVS commit by staikos: 

activate the fieldListIsComplete() member in datasources to prevent users from
entering vectors that don't exist when we know the complete set.

note: data wizard surely doesn't work well with sources where we don't know
  the full set though
