This is a problem with the JSF spec, and currently there is nothing
that MyFaces can do about it.
If you look inside of UIInput's validate() method, you'll see why your
validator is not firing.
The validate method checks if the submittedValue is null. If so, it
does nothing.
According to the HTML spec, if you don't select anything in a listbox,
nothing gets put onto the request, which means that the submittedValue
will be null.
