Thanks Michael, both of those are helpful.
I have a few extra questions though:
Regarding ActionDispatcher -
* The ParameterListActionDispatcher class isn't in the 1.2.8 struts
distribution that I downloaded, and is linked as a bugfix. Do I need
to download the entire struts source, add this in and recompile, or is
there an easier way?
Regarding DataEntryForm -
* In sections 6 & 7 it describes a class
ParameterMappingDispatchAction that I also don't see in the
distribution (nor in the javadocs online). Is this referring to the
ParameterListActionDispatcher class or something else? Conceptually it
seems to be describing the same thing. If not is there an example of
what step 7 is describing?
All that aside, when I turn off automatic validation, can I still call
the validation manually in my action code? ie. Something like :
ActionErrors errors = form.validate(mapping, request);
if (!errors.isEmpty()) {
// determine which forward key to use based upon which step I am
in the process
forward = mapping.findForward(forwardKey);
saveErrors(request, errors);
return forward;
}
Is there anything else I need to do to validate the form manually?
Thanks
Chris
