我的CustomListDefinition和CustomEventReceiver存在问题。
ListDefinition工作正常。我可以创建列表，一切看起来都应该如此。我的EventReceiver对以下四个事件起作用：ItemAdding，ItemAdded，ItemUpdating和ItemUpdated。
通过WebInterface添加/更新ListItems时，每个方面都可以正常运行。当我尝试通过C＃（或PowerShell）创建或编辑ListItem时，出现以下错误：
“未知状态模块：33消息：134”
即使代码真的没有！我用一个新的空EventReceiver重现了这个问题，它连接到我的自定义ListDefinition的ItemUpdating事件。
仅在 ItemUpdating 事件中出现此问题。当我在没有此事件的情况下部署我的解决方案时，一切都进展顺利。将EventReceiver部署到标准列表（例如，Task ListDefinition）也没有像上面那样的问题。
所以我的结论是，我的ListDefinition一定有错误。
有人可以帮我找错吗？

代码有点匿名，因此可能包含一些输入错误。 ;）
希望你能帮我找到问题。
编辑： 我发现，事件日志中发生了这个错误：
加载并运行事件接收器时出错 OC.Sommerfest中的MyProject.BookingItemEventReceiver，版本= 1.0.0.0， Culture = neutral，PublicKeyToken = asdasdasd。其他信息是 下方。
事件ID为6875。
答案 0 :(得分：0)
尝试使用set false更新EventFiringEnabled期间的listitem代码。
类似的东西：
this.EventFiringEnabled = false;
//item updated logic
this.EventFiringEnabled = true;
答案 1 :(得分：0)
我有同样的问题，我目前正试图解决。 就我而言，使用网站内容菜单创建的自定义列表。
但是我检查了在catch中发生错误时出现了未处理的异常。
另一个原因可能是您在错误消息中重新记录的字符串的长度很长。
如果我找到一个新的解决方案，我会分享。
问候......
