Subject RE: RequiredIf Example Request
Date Fri, 24 Jan 2003 20:39:27 GMT
I just barely ran into this problem.  Seems that all the field checks
are run.  Checking the Validator example (TowFieldCheck) in the struts
docs (1.1b3), It seems that if the value is null, you should let it pass
as accepted.

The xml defining the field is the one that should specify that the field
is required.  id: required,mycheck

Then it becomes possible to have an optional field.
