Orchard CMS - 内容部分（编辑）不将数据发布到服务器

Question

我创建了一个新的内容部分。我将内容部分附加到页面内容项。编辑“页面内容”项时，自定义内容部件编辑器（我创建的）显示正确，仅包含两个字段。

当我填写数据并点击“保存”时，驱动程序的POST编辑器操作正在接收自定义部件的空值。我在Part类中使用InfoSet。但是，我还创建了一个迁移来为部件记录创建表。

以下是一些代码：

using Orchard.ContentManagement;
using Orchard.ContentManagement.Records;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;

namespace SlideShare.Models
{
    public class SlideSharePartRecord : ContentPartRecord
    {
        public virtual string SlideShareId { get; set; }
        public virtual int StartFromSlide { get; set; }
    }

    public class SlideSharePart : ContentPart<SlideSharePartRecord>
    {
        [Required]
        public string SlideShareId
        {
            get { return Retrieve(x => x.SlideShareId); }
            set { Store(x => x.SlideShareId, value); }
        }

        [Required]
        [Range(1,20)]
        public int StartFromSlide
        {
            get { return Retrieve(x => x.StartFromSlide); }
            set { Store(x => x.StartFromSlide, value); }
        }
    }
}

using Orchard.ContentManagement.Handlers;
using Orchard.Data;
using System;
using System.Collections.Generic;
using SlideShare.Models;

namespace SlideShare.Handlers
{
    public class SlideShareHandler : ContentHandler
    {
        public SlideShareHandler(IRepository<SlideSharePartRecord> repository)
        {
            Filters.Add(StorageFilter.For(repository));
        }
    }
}

using Orchard.ContentManagement;
using Orchard.ContentManagement.Drivers;
using SlideShare.Models;
using System;
using System.Collections.Generic;

namespace SlideShare.Drivers
{
    public class SlideShareDriver : ContentPartDriver<SlideSharePart>
    {
        protected override string Prefix { get { return "SlideShare"; } }

    protected override DriverResult Display(SlideSharePart part, string displayType, dynamic shapeHelper)
    {
        return ContentShape("Parts_SlideShare", () => shapeHelper.Parts_SlideShare(
                        SlideShareId: part.SlideShareId,
                        StartsFromSlide: part.StartFromSlide));
    }

    // GET
    protected override DriverResult Editor(SlideSharePart part, dynamic shapeHelper)
    {
        return ContentShape("Parts_SlideShare_Edit", () => shapeHelper.EditorTemplate(
                TemplateName: "Parts.SlideShare",
                Model: part,
                Prfix: Prefix));
    }

    // POST
    protected override DriverResult Editor(SlideSharePart part, IUpdateModel updater, dynamic shapeHelper)
    {
        updater.TryUpdateModel(part, Prefix, null, null);
        return Editor(part, shapeHelper);
    }
}
}

@using System.Web.Mvc.Html
@model SlideShare.Models.SlideSharePart

<fieldset>
    <legend>@T("SlideShare Presentation Fields")</legend>

    <div class="editor-field">
