title: ASP.NET MVC OnActionExecuted ActionFilter
body: <p>I trying to check if an exception has been raised by an action with the <strong>filterContext.Exception</strong> below: </p>
  
  <pre><code> public class Test : ActionFilterAttribute
      [...]   
      public override void OnActionExecuted(ActionExecutedContext filterContext)
              {
                  if (filterContext.Exception != null)
                  {
                       continue;
                  }
              }
  </code></pre>
  
  <p>in controller:</p>
  
  <pre><code>        [Test]
          [AcceptVerbs(HttpVerbs.Post)]
          public ActionResult Login(Usuarios usuario)
          {
              try
              {
               throw new Exception();
              }
             catch
             {
  
             }
  
           }
  </code></pre>
  
  <p>The <strong>filterContext.Exception</strong> is always null.I can't catch this information here.</p>
  
  <p>Any ideias?</p>
