DynaValidatorForm
When you're using DynaValidatorForm and the page has two buttons
(e.g. "Commit" and "Cancel"), how do you not validate if the user
hits the "Cancel" button (which on my page, also submits, but the
action checks the value of the submit button)?
Do I have to write a Form subclass to do this? Can you have a
hand-coded Form subclass and use the Validator rules as well?

Instead of
if (errors.size() > 0) {
request.setAttribute("org.apache.struts.action.ERROR", errors);
forward = "failure";
}
I would write :
if (! errors.isEmpty()) {
saveErrors(request, errors);
forward="failure";
}

Now *that* is slick. Thanks.

Adam,
You are right.
I just wrote something more generic.

Why get complicated? All you need is <html:cancel/> and the validation
will automatically not be executed. Even the javascript validation if
you are using DynaValidatorForm.

Thanks, I got that to work without resorting to a DispatchAction
like this:
if (confirm.equals(cancel)) {
forward = "complete";
} else {
errors = dynaForm.validate(mapping, request);
if (errors.size() > 0) {
request.setAttribute("org.apache.struts.action.ERROR", errors);
forward = "failure";
}
}
Is that the right way to put the errors in play?

Glenn,
- Use a descendant of DispatchAction for your form's action,
- Have two separate methods in the action class for your two buttons
(one for 'commit' and one for 'cancel').
- In the struts-config.xml file, specify attribute 'validate' to 'false'
for your form's action.The form validation wont't happen automatically
this way.
- In the method for the 'commit' button, call explicitely 'validate' on
your form. But not in the method associated to the cancel button.
Hope this helps.

But those would be done in the action class, right? I'm wondering
if this can be done using a DynaValidatorForm -- the Validator is
tossing me back to the input page before the action is invoked.

If your buttons have values set then you can test to see which button
value was submitted. Even better though with struts you can use the
built-in cancel button without needing to do that. <html:cancel/> and
then check action.isCancelled(request)
