Subject RE: Validating fields only in some situations question....

I asked pretty much the same question a few hours ago. Heres the answer I

Not sure if anybody answered you question or not yet but there are a couple
things you can do...

1. Have many action mappings to one DispatchAction.  
<action path="/a" parameter="subtask" type="my.Dispatch" ...> ... </action>
<action path="/b" parameter="subtask" type="my.Dispatch" ...> ... </action>

link to each as "/" and "/" and then
do validation per action and not per form.

The other alternative suggested by Robert Taylor, which, once set up, is
pretty slick but involves a little extension to how validator works:

Subject: DispatchActions - using form validation for only some methods


I've just moved to using dispatch actions from my own implementation of
something similair to relay actions. One facility my implementation gave me
was to have the form validated when some actions were called, and not
validated for other actions (at the expense of a bloated struts-config.xml).

Using dispatch actions I am now explicitly calling the form's validation for
those methods that require a validated form:

        ActionErrors errors = form.validate(mapping, request);
         if(!errors.isEmpty()) {
             saveErrors(request, errors);
             return new ActionForward(mapping.getInput());

Is there a better way of achieving this?

Subject: Validating fields only in some situations question....

Hello, I have a question :

I am using Validator framework with Struts. I have a login form on my
web page which is associated
with 3 buttons - Login, to log the user in
		 Reset , to reset the form fields
		 Register, which brings the user to a new registration page

I use only one Action of the type DispatchAction which determines what
exactly to do.

My question is : how can I tell the Validator framework to perform
validation only when the user presses the Login button
and to ignore the vallidation when the users presses any of the two
other buttons ?
