无法更新 CRM 2011 自定义实体上的 OptionSetValue 字段

Question

我收到“指定的演员表无效”。尝试更新自定义实体上的自定义字段的 OptionSetValue 属性时出现异常。

这行得通：

data = new Xrm.Xyz_data()
{
  Xyz_dataId = (Guid)entity["xyz_dataId"],
  // Xyz_dataStatus = new OptionSetValue(5),
  Xyz_IsSyncReqd = true
};

service.Update(data);

但取消注释 OptionSetValue 行并抛出此异常：

System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: Specified cast is not valid. (Fault Detail is equal to Microsoft.Xrm.Sdk.OrganizationServiceFault).

有了这个堆栈跟踪：

这对我来说是正确的 - 我没有使用您正在使用的早期绑定，但您能否验证自创建和发布选项列表属性以来数据上下文是否已刷新？

如果这是一个内置状态字段，您可能需要先进行更新，然后再执行 UpdateStateValueRequest。摘自 CRM 2011 SDK -

#region 如何更新状态值 // 将状态值标签从 Active 修改为 Open。 // 创建请求。 UpdateStateValueRequest updateStateValue = 新的 UpdateStateValueRequest { AttributeLogicalName = "状态码", EntityLogicalName = Contact.EntityLogicalName， 值 = 1， 标签 = 新标签（“打开”，_languageCode） }; // 执行请求。 _serviceProxy.Execute(updateStateValue); #endregion 如何更新状态值

所以我终于弄清楚发生了什么。我使用与 CRM 4.0 相同的注册表设置打开了服务器端调试：

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM]
"TraceEnabled"=dword:00000001
"TraceCategories"="*:Error"
"TraceCallStack"=dword:00000001
"TraceRefresh"=dword:00000001 

我重新运行了失败的测试，发现了这个错误：

由于我通过单元测试调试我的插件，我意识到当我的插件更新这些字段时，另一个插件被触发，并且该插件显然导致了异常。但更糟糕的是，异常处理程序引发了另一个异常，该异常被返回，掩盖了真正的异常。我通过吃掉异常处理程序可能抛出的任何异常来测试一个非常简单的修复程序，现在它工作得很好！现在来看看为什么我的其他插件失败了......
