We have a similar situation using action classes based on the
LookupDispatchAction. We have not implemented this yet, but our approach
will be to have two action mappings. We'll do the following:
In the form class, we'll override validate() to do three things:
1) call super.validate().
2) If ActionErrors are returned, we'll change the dispatchAction (used to
map to the method) in the form/request, adding something like
"ValidationFailed" to the existing value.
3) Return the ActionErrors.
The first mapping will have validate="true", so the server-side validation
will be used. The input attribute will be a forward to the second mapping,
which will look exactly like the first, except that validate will be set to
"false".
The second mapping will look like the first, but validate will be "false".
It will be responsible for forwarding back to the edit page from which the
validation error originated.
The ActionClass (actually the super class that implements some default
behaviors) will also implement methods to support the possible validation
failure methods. These methods will simply forward to the appropriate
mapping, insuring that the form is in the request - if applicable, any
other needed objects would be addressed here as well. For example
(simple):
public ActionForward saveNewValidationFailed ActionMapping mapping,
ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException,
ServletException {
request.setAttribute(EDIT_FORM_NAME, form);
return mapping.findForward(FORWARD_ADD)
}
public ActionForward saveUpdateValidationFailed ActionMapping mapping,
ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException,
ServletException {
request.setAttribute(EDIT_FORM_NAME, form);
return mapping.findForward(FORWARD_EDIT)
}
I can't guarantee that this is the right way, or even that it would work
since we have yet to implement it, but it sounds reasonable to our team.

Please respond to
"Struts Users
Mailing List"
if you want to use different validation rules with the validator you
have to declare different action elements in your struts-config.xml file
(using the same action class if you want).
another means is to validate your form in the methods of your action
class as propose Koni in the mail sent on the list Monday, August 25,
2003 8:04 PM:
struts-config.xml:
<action path="/logon/action/logon"
type="test.web.struts.action.logon.LogonAction"
name="logonForm"
scope="request" <-- !!!
validate="false" <-- !!!
input="/WEB-INF/jsp/logon/logon.jsp">
<forward name="success" path="/index.jsp"/>
</action>
LogonAction.java:
ActionErrors errors = new ActionErrors();
errors = form.validate(mapping, request);
// Report any errors we have discovered back to the original form
if (!errors.isEmpty())
{
saveErrors(request, errors);
return new ActionForward(mapping.getInput());
}
