I've to make a field REQUIRED depending on the value of another radio button.
I've created a servervalidation.jsp for the Constraint and set this one on the field. The problem is that if a remove the REQUIRED flag from the field, and I write nothing in the field, the servervalidation is not called.
If I check the required flag it will test the field value independently from the radio button value, so it stops before my servervalidation logic.
So: field component required flag: checked field component contraint: my contraint result: stops on empty field value before my contraint logic
field compoenent required flag: unchecked field component contraint: my contraint result: read my contraint logic ONLY if a value is written (not in the case the field is empty)
Is there a way to rewrite REQUIRED logic in a conditional way?
