Allow for Required Option in VisitorFieldValidator
--------------------------------------------------
Key: WW-3477
URL: https://issues.apache.org/jira/browse/WW-3477
Project: Struts 2
Issue Type: Improvement
Components: Other
Reporter: Robert Nelson
Priority: Minor
A number of projects I'm working on make use of the VisitorFieldValidator to
pass validation handling back to our entity beans. In some cases we have a bean
being set which is completely optional for the user. One example would be a
Phone object representing a fax number. We have a bean, and it needs validation
if they gave filled in those form fields, but if they didn't we don't need
validation at all. If we apply the VisitorFieldValidator to that bean in the
action it always validates against the bean even if the bean is completely
empty (or filled with empty Strings). I would like to have the ability to mark
a VistiorFieldValidation as optional, meaning if no properties were passed in
for that bean it would not execute that bean's validators.
I've written a custom validator to accomplish this which I've been using for a
while, but I'd like to see this feature in the provided validator so others can
use it. I imagine adding a property on the VisitorFieldValidator called
"required" which would default to "true".
I'm willing to write the code for this, but I'd like some input on the idea and
some instructions on how I can help.
