我有一个插件可以更新实体上的一个字段,该字段也会触发更新。我正在尝试检查Status是否已更改为“Scheduled”并保存,然后Sharepoint中必须存在某些文档类型。来自Sharepoint的数据无需任何延迟即可检索。问题是插件需要太长时间或抛出错误: UnhandledException:System.ServiceModel.FaultException:需要在commitDetail之前启动事务:ErrorCode:-2147220911
请参阅提供的代码并帮助我......

在插件注册工具中,我已经注册了事件插件:预操作(CRM 2011),同步。
我可能做错了。请建议我是否必须使用PreImages或错误注册插件。 如果需要更多信息,请告诉我...... 谢谢!

在插件中,这将是有问题的代码:
catch(FaultException<OrganizationServiceFault> ex) {
_TracingService.Trace("The application terminated with an error.");
_TracingService.Trace("Timestamp: {0}", ex.Detail.Timestamp);
_TracingService.Trace("Code: {0}", ex.Detail.ErrorCode);
_TracingService.Trace("Message: {0}", ex.Detail.Message);
_TracingService.Trace("Inner Fault: {0}",
null == ex.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
}
当你的代码吞下FaultException
时,它会破坏交易,通常 - 我会说 - 总是会导致错误。
您需要查看正在捕获的跟踪详细信息,以查看导致初始FaultException
的原因。
在我用于插件的通用错误处理代码中,我总是在捕获InvalidPluginExecutionException
后抛出FaultException
,因为一旦发生,事务几乎没有成功完成。
