Dynamics CRM 2011 InvalidWorkflowException

Question

我有2个自定义实体和一个日历规则列表，我试图将每个规则解析为第3个自定义实体的单独列表，每天1或2个。 然后，我将这些列表合并在一起，以构成一个包含正确实体的最终列表。

现在，我在尝试通过生成所有实体来完成工作流之前对其进行调试，但是我必须首先修复一些处理错误。

我得到的错误：

Unhandled Exception: System.Activities.InvalidWorkflowException: The following errors were encountered while processing the workflow tree:

一旦我开始执行，执行末尾的3行仅用于最终调试。

我试图用谷歌搜索为什么失败了，但是我似乎找不到任何信息。

编辑：弄清究竟是什么导致工作流错误。

Answer 1

现在这是一个相当古老的问题，但是我仍然可以回答，因此有记录可供其他人查找。

问题实际上在于工作流程过程创建的执行方式。 要分析自定义工作流程，需要一个引用该工作流程的步骤。 该参考将输入到流程创建窗口底部的面板中。 添加步骤后，将出现一个文本框，邀请您添加描述。 在任何情况下都不要输入任何东西。 尝试手动运行工作流程时，此文本框中的任何内容都会导致失败。

比较我的描述：“ Exercises CreateQuoteApprovalMatrix”-错误消息：“ CustomActivityStep1：练习CreateQuoteApprovalMatrix_1_converted”。 删除说明后，我就可以成功调试。

Answer 2

我发现这个问题与代码本身无关。 我收到了90％的代码被注释掉的错误。 显然，工作流调试器如何处理早期绑定是一个问题。 一旦我注释掉早期绑定，它就会产生另一个与插件调试器本身有关的错误，该错误甚至只用3行代码即服务注册就触发了。

因此，我决定使用其他调试方法，即明智地使用traceInfos。 我还从中注意到，我应该首先在本地测试我的应用程序，因为使用DateTimes处理循环时，无限循环的风险很大。
