I can't test this right now, but if I have an ActionMapping with validate="true" and no input, won't that result in an
error when validate fails? My understanding is that if validate fails, the request processor forwards the request to
the input.

Just set up an forward for validation failure. You can do this in your
struts-config.xml file, in fact you can have as many forwards as you
like, but for practical purposes most people prefer to have at most three
or four forwards per Action. For example, you might have a SaveAction that
forwards to the next screen in a sequence if validation succeeds, an error
page if it fails, a login page if the session becomes invalidated, and a
query action if you had a "delete" button to delete a record.
Just say you query a database to populate your form fields. Then you can
edit the form and hit Save. In the Form's validate method you fill an
ActionErrors object.
Then in the SaveAction you will have something like:
// If a message is required, save the specified key(s)
// into the request for use by the <struts:errors> tag.
if (!errors.isEmpty())
{
saveErrors(request, errors);
// Forward control to the appropriate 'failure' URI
forward = mapping.findForward("failure");
}
else
{
// Forward control to the appropriate 'success' URI if no errors
forward = mapping.findForward("success");
}
return forward;
and in your struts-config you will have something like:
<action path="/saveAction"
type="myproject.actions.SaveAction"
name="somethingForm"
validate="true">
<forward name="success" path="nextForm/>
<forward name="failure" path="somethingForm"/>
</action>
I hope you can figure out your answer from that... I can't give you a real
example from my project because of confidentiality so I have to try and
make it generic.
