Alexander -
Usually when I have this situation I just put in an else (or a
logic:notEqual in your case) which prints out the form field as hidden with
some "bogus" data in it. That "bogus" data will be enough to make the
validation pass of course.
I had thought about doing the requiredifpresent or something like that, but
this always seemed much simpler.
