Empty model when submitting asp.net mvc 2 form

I gotta the following code in controller and view. The problem is that the model(Photo is an Entity Framework entity) is empty(all fields are nulled). Why?

// GET: /Admin/Photo/Create

    public ActionResult Create()
    {
        return View();
    } 

    //
    // POST: /Admin/Photo/Create

    [HttpPost]
    public ActionResult Create(int id, FormCollection collection)
    {
        try
        {
            var file = (HttpPostedFileBase) Request.Files[0];
            if (file != null && file.FileName != null)
            {
                var filename = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Photos/Product/", Path.GetFileName(file.FileName));
                file.SaveAs(filename);
                var photo = new Photo();
                photo.Description = collection["Description"];
                photo.Main = collection["Main"].Contains("true");
                photo.Filename = Path.GetFileName(file.FileName);
                photo.Product_Id = id;
                Entities.AddToPhotos(photo);
                Entities.SaveChanges();
            }
            else
            { 
                ModelState.AddModelError("", "Plik musi zostać załadowany.");
                return View();
            }


            return RedirectToAction("Index");
        }
        catch
        {
            return View();
        }
    }


<h2>Create</h2>

<% using (Html.BeginForm(null, null, null, FormMethod.Post, new {enctype = "multipart/form-data" })) {%>
    <%: Html.ValidationSummary(true) %>

    <fieldset>
        <legend>Fields</legend>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Description) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.Description) %>
            <%: Html.ValidationMessageFor(model => model.Description) %>
        </div>

        <div class="editor-label">
            <label for="MainContent_file">Plik: </label>
        </div>
        <div class="editor-field">
            <asp:FileUpload ID="file" runat="server" />
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Main) %>
        </div>
        <div class="editor-field">
            <%: Html.CheckBoxFor(model => model.Main) %>
            <%: Html.ValidationMessageFor(model => model.Main) %>
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>

<% } %>

<div>
    <%: Html.ActionLink("Back to List", "Index") %>
</div>

Update: I checked and the collection is populated with proper fields, but they are all nulled.

Check the html source in the browser.

It might be sending them as: "Photo.Description"

Check to make sure that the name attributes in the resulting html match your collection name. You could also change your public ActionResult Create(int id, FormCollection collection) to public ActionResult Create(int id, YourViewModel model) to automagically map the post values to the model.
