HandleErrorAttribute not working

Question

I have started an MVC 3 template project in VS10 and modified global.asax.cs as such:

public static void RegisterGlobalFilters(GlobalFilterCollection filters

You shouldn't set properties when registering a global action filter. You could write a custom handle error filter:

public class MyHandleErrorAttribute : FilterAttribute, IExceptionFilter
{
    public void OnException(ExceptionContext filterContext)
    {
        if (!filterContext.IsChildAction && (!filterContext.ExceptionHandled && filterContext.HttpContext.IsCustomErrorEnabled))
        {
            Exception innerException = filterContext.Exception;
            if ((new HttpException(null, innerException).GetHttpCode() == 500))
            {
                var viewName = "AllOtherExceptions";
                if (typeof(DivideByZeroException).IsInstanceOfType(innerException))
                {
                    viewName = "DivideByZeroException";
                }

                string controllerName = (string)filterContext.RouteData.Values["controller"];
                string actionName = (string)filterContext.RouteData.Values["action"];
                HandleErrorInfo model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName);
                ViewResult result = new ViewResult
                {
                    ViewName = viewName,
                    ViewData = new ViewDataDictionary(model),
                    TempData = filterContext.Controller.TempData
                };
                filterContext.Result = result;
                filterContext.ExceptionHandled = true;
                filterContext.HttpContext.Response.Clear();
                filterContext.HttpContext.Response.StatusCode = 500;
                filterContext.HttpContext.Response.TrySkipIisCustomErrors = true;
            }
        }
    }
}

and then register it:

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new MyHandleErrorAttribute());
}
