我试图做的是为保存的产品创建一个“超级”实体类。根据产品在应用程序中的位置，某些额外属性是必需的（但并非总是如此）。
例如，当产品在网格中使用时，我希望有一个派生自实体的 ViewModel（继承所有公共字段），然后添加一个唯一标识符属性，如“rowNumber”，以便剑道 ui 轻松搜索网格 CRUD。
我以为我已经完成了所有这些工作，但我遇到了一个障碍……一切都很好并且运行正常，直到我单击批处理网格的“保存”。它执行该函数并且所有数据都存在，但是当它从 CRUD 返回时，它会中断。在萤火虫中，我看到一个异常被抛出，但它永远不会完成（ajax 微调器停留在那里）并且异常中的所有信息都是空的......
我不确定这是否是 c# 不能很好地与 CSLA 配合使用的问题。我不确定。
任何帮助，将不胜感激！我无法上传图像，因为我的代表不够高，否则我会放一张异常的图片，但我至少会放出 Firebug 控制台中出现的内容。其他关于它的一切都是空的......
无限执行且无响应的异常：
GET http://localhost:32574/Exception/SystemException/00000000-0000-0000-0000-000000000000
实体： 这个文件是由 CodeSmith 模板自动生成的，所以它有点荒谬，但它包含出现在视图中的字段值（见下文）。视图上的内容与实体中的内容的例外是实体中未“展平”的字段，因为 Kendo UI 当前不支持可编辑网格内部的这一点。
视图模型：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace Project.MVC.Models
{
//The MetaData Class is where to put all annotations and validations
[MetadataType(typeof(Project.Business.Shipment.ItemMetaDataClass))]
public class ItemModel : Project.Business.Shipment.Item
{
public ItemModel()
{
}
public long rowNumber { get; set; }
public decimal Length { get; set; }
public decimal Width { get; set; }
public decimal Height { get; set; }
[Display(Name = "UoMDim")]
[UIHint("ItemGrid_RefUnitOfMeasurementListingDimension")]
public string DimensionUnitOfMeasure { get; set; }
[Display(Name = "UoMW")]
[UIHint("ItemGrid_RefUnitOfMeasurementListingWeight")]

[UIHint("ItemGrid_RefUnitTypeListing")]
public string QuantityUnitOfMeasure { get; set; }
