The pattern is to create a local instance of ActionErrors. Then add to
it if any errors occur. At then end, look to see if it is empty or not
(errors.empty()). If it is not empty, then somebody posted soemthing,
and you should call saveErrors() and branch to your error page.
Otherwise, you can save your own objects and branch to success.
