"System.Workflow.Runtime.Hosting.PersistenceException“自定义SharePoint顺序工作流
"System.Workflow.Runtime.Hosting.PersistenceException“自定义SharePoint顺序工作流
提问于 2012-03-23 22:45:20
我在具有自定义活动的sharepoint Visual Studio顺序工作流的SharePoint日志中收到以下错误。
自定义活动是通过Component Class创建的。
我不确定为什么会出现这个错误？请帮帮我！

问题是因为当我将Component类更改为Sequential Activity时，我具有Activity属性，例如'A‘和'B’。然后，我将此活动添加到VS工具箱。在这个阶段，它工作得很好。
现在，当我更改活动代码以将其属性更改为'A‘和'C’时，我还删除了一个带有参数的构造器作为'Container‘对象。
当我重新编译这个活动并刷新它的DLL时。在工作流设计器中，活动未刷新，即其工具箱仍指向旧的dll。
为了解决这个问题，我关闭并再次打开了VS，瞧，设计器现在得到了具有新属性的。
我认为这是VS工具箱的局限性，它没有得到刷新-尽管dll的活动是更新的。
谢谢!

您是否可以访问工作流的源XAML？查看是否包含"Container“对象，以及是否有必要将其包含在其中。如果您可以将其删除，但仍能使工作流正常运行，则可能会解决此问题。
