DynaValidatorForm question:

[James Drinkard]

Hello All,
I'm converting a simple simple form application to use the DynaValidatorForm and I believe I have the plugins and xml files configured properly. My question is: how do I code for the validation in the action class? My code is:
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
{
DynaValidatorForm f = (DynaValidatorForm) form;
System.out.println(f.toString());
//ActionErrors errors = new ActionErrors();

ActionErrors errors = f.validate(mapping, request);
System.out.println(errors);

// Report any errors we have discovered back to the original form
if (!errors.empty())
{
saveErrors(request, errors);
return new ActionForward(mapping.getInput());
}

// Forward control to the specified success in the struts-config.xml file.
return (mapping.findForward("success"));
}
but ActionErrors never get thrown, even though I use "required" to check for null fields on the submit from the jsp form.

Not sure what I have wrong here.
Thanks,
James
