Redirect should be done after success, not after failure

[Rossen Stoyanchev]

Currently the controller method is implemented to redirect after validation failure and does not on success. It should be the other way around.

Something like this:

@RequestMapping(value="/", method=RequestMethod.POST)
public String enterAge(@Valid Person person, BindingResult bindingResult) {
    if (bindingResult.hasErrors()) {
        return "results";
    }
    return "redirect:/";
}
