Ah, good to know. The reason I needed a list of validators is because I
have a form that requires either an email address or a phone number and
carrier. If they fill in the phone number, they must select a carrier. So
I want to have an extra validator on the carrier field of the form,
IS_EXPR(str(request.vars.phone == '' or request.vars.carrier !=
''),error_message='please enter a carrier'). I'm side-stepping this
problem right now by attaching this validator to the phone field, but now
that I know how to specify a drop-down, I can do this better.
