我偶尔会遇到这个错误(它大约在2个小时前发生,但现在我没有收到错误)当启动K2表单(使用调用WCF服务的K2 SmartObjects)时。 当我不断收到错误时,它似乎处于不同的功能
http://tempuri.org/:GetAccountDetailsForWorkflowResult http://tempuri.org/:GetNewAccountFormInitializationDataResult
InnerException消息始终是相同的:' ValueType' System.Int32'不能为空。'
Error: The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:GetAccountDetailsForWorkflowResult. The InnerException message was 'ValueType 'System.Int32' cannot be null.'. Please see InnerException for more details.
为什么我会收到此错误,为什么现在当我调出相同的工作流程时,我不再收到错误了? 此外,我们在2个测试环境中测试了相同的工作流程和服务,并且没有错误。
这可能是网络或服务器的问题吗?
如何找到哪些变量给出了错误InnerException消息是' ValueType' System.Int32'不能为空。' ?
这是班级
