Does anyone know how to validate a form -- using the normal Data::FormValidator interface -- for a case where there are two text fields, of which at least one needs to be filled in?
Specifically, I have a form with two fields, Zip Code and Postal Code, and I need to make sure that either one or the other is filled, then use a constraint to validate the filled field.
I've tried several approaches, but I'm stumped. I would prefer not to hack the module (or subclass it) unless absolutely necessary, but that looks like the next step.
