cross field validation with empty fields
Hello, we are using T4.1
We have to validate a form and we don't want to do it client side.
Let say we have three text fields.
The validation should implement the following rule:
if (fielda="") && (fieldb="" || fieldc="")
then throw new Exception("");
The problem is that we cannot link the validation to neither field
because they can be empty and the custom validator we are trying to
implement is nevere called if the field is empty.
We tried to follow the Identity validator but it is also not called
when the field to which is associated is empty.
Is there another way to accomplish cross field validation ?
It seems to us that in T4.1 lacks a validator attribute for the form
component.

See http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/form/validator/Validator.html
Probably just override getAcceptsNull()
