title: Javax validation not giving error messages
body: <p>I'm using javax validation. I have this xml:</p>
  
  <pre><code>&lt;context:annotation-config/&gt; 
      &lt;!-- Configures the @Controller programming model --&gt;
      &lt;mvc:annotation-driven /&gt;
      &lt;!-- Forwards requests to the "/" resource to the "index" view --&gt;
      &lt;mvc:view-controller path="/" view-name="front"/&gt;
      ....
   &lt;context:component-scan base-package="fi.utu.tuha.controller" /&gt;'
  </code></pre>
  
  <p>And controller:</p>
  
  <pre><code>public String ready(@ModelAttribute("netdriveOrder")@Valid NetdriveOrder netdriveOrder,
               Model model, BindingResult result) {
         if (result.hasErrors()) {
             return "order";
         } else {
             return "order_confirmed";
     }
  </code></pre>
  
  <p>I don't see a fault, but I get this:</p>
  
  <p>Exception</p>
  
  <pre><code>org.springframework.web.bind.annotation.support.HandlerMethodInvocationException:
  Failed to invoke handler method [public java.lang.String
  fi.utu.tuha.controller.NetDriveOrderFormController.ready(fi.utu.tuha.domain.NetdriveOrder,org.springframework.ui.Model,org.springframework.validation.BindingResult)];
  nested exception is java.lang.IllegalStateException:
