Subject Validation based on other fields
Date Thu, 04 Sep 2008 15:38:06 GMT

In Struts 2, I need to perform some validation based on other fields

	if cardType = 'Switch', issueNumber is mandatory

I was looking for something like the validWhen tag from Struts 1. I'd
like to do it with the client side javascript if possible (to prevent
having to reload the page just for validation) but I can't find anything
in the Xwork docs. 

Do I have to do this kind of validation in the action class itself e.g.
(from the docs):

More complecated validation should probably be done in the validate()
method on the action itself (assuming the action implements Validatable
interface which ActionSupport already does).

Not a problem if I do - I can move all the validation to the Java, but
I'd just like to know either way
