Standard model binding and complex types that include a list

Question

I am using RC1 ASP.NET MVC.

I am trying to expand the example of binding the Phil Haak model . I am trying to use the default binder to bind the following object:

public class ListOfProducts
{
    public int Id { get; set; }
    public string Title{ get; set; }
    List<Product> Items { get; set; }
}

public class Product
{
    public string Name { get; set; }
    public decimal Price { get; set; }
}

I use the code from Phil's example with some changes:

Controller:

using System.Collections.Generic;
using System.Web.Mvc;

namespace TestBinding.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewData["Message"] = "Welcome to ASP.NET MVC!";

            return View();
        }

        //Action method on HomeController
        public ActionResult UpdateProducts(ListOfProducts productlist)
        {
            return View(productlist);
        }
    }

    public class Product
    {
        public string Name { get; set; }
        public decimal Price { get; set; }
    }

    public class ListOfProducts
    {
        public int Id { get; set; }
        public string Title { get; set; }
        List<Product> Items { get; set; }
    }
}

View:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>

    <asp:Content ID="indexHead" ContentPlaceHolderID="head" runat="server">
        <title>Home Page</title>
    </asp:Content>

    <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server">
        <form method="post" action="/Home/UpdateProducts">
            <input type="text" name="productlist.id" value="99" />
            <input type="text" name="productlist.Title" value="SomeTitle" />

            <input type="hidden" name="productlist.Index" value="0" />
            <input type="text" name="productlist.items[0].Name" value="Beer" />
            <input type="text" name="productlist.items[0].Price" value="7.32" />

            <input type="hidden" name="productlist.Index" value="1" />
            <input type="text" name="productlist.Items[1].Name" value="Chips" />
            <input type="text" name="productlist.Items[1].Price" value="2.23" />

            <input type="hidden" name="productlist.Index" value="2" />
            <input type="text" name="productlist.Items[2].Name" value="Salsa" />
            <input type="text" name="productlist.Items[2].Price" value="1.23" />

            <input type="submit" />
        </form>
    </asp:Content>

My problem is that simple types (Id and Title) are displayed in the productlist object, but not in the List. So:

• Is my code bad (don't be surprised)?
• Can the model middleware handle ListOfProducts objects by default?
• If the middleware does not handle this type of object by default, what do I need to do (examples, if possible)?

Thanks in advance.
