I'm curious about what would be best practice for doing "conditional
constraints", such as: if fieldA's value is 'foo', then fieldB is
required; or if fieldA's value is 'bar', then fieldB must have the value
'baz'. Have other people had to do something like this? What would be
a good way to accomplish it?
Perhaps a constraint derived from HTML::FormFu::Constraint::_others,
with some additional configuration available...
thanks,
Ronald
