Maybe i`ll better rephrase my question to make it more easy for the reader
:)
I want to make a field in a form required when it exists on the form
if it is not on the form (due to some logic tags that make it disappear), I
dont want to generate an error.
How would I best solve this?
make a new validator "requiredifpresent" ?
or could I use the requiredif together with some logic based on values in
other beans ?
