Некоторые поля не отображаются в ModelBinder

Ниже приведен код моего контроллера:

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Edit(int id, Actor actor)
    {

        try
        {
            actorRepository.Save(actor);
            return RedirectToAction("Index");
        }
        catch
        {
            return View("Edit");
        }
    }

Вызывающее представление имеет частичное представление, строго типизированное для класса Actor. По какой-то причине есть несколько полей, которые не привязаны к классу. Речь идет о полях Address, Address2 и ZipCode. Они заполняются на странице, но возвращаются нулевыми. Здесь есть все остальные поля, но только не эти.

Любые идеи? Кроме того, как я могу написать модульный тест, чтобы повторить это поведение?

    public string ZipCode { get; set; }

    [Required(ErrorMessage = "Even in theater, you have to choose a gender")]

}
