「System.Workflow.Runtime.Hosting.PersistenceException」自定義SharePoint順序工作流程

Question

我在具有自定義活動的SharePoint Visual Studio順序工作流的SharePoint日誌中收到以下錯誤。

自定義活動通過組件類創建。

我不知道爲什麼會出現這個錯誤？請幫忙！！！

Answer 1

您可以訪問工作流的源XAML嗎？查看是否包含「Container」對象，以及是否有必要在其中包含該對象。如果您可以將其刪除並使工作流程正常運行，則可以解決問題。

Answer 2

問題是因爲當我將組件類更改爲順序活動時，我有活動屬性，例如'A'&'B'。然後我將這個活動添加到VS工具箱。在這個階段它工作得很好。

現在，當我更改活動代碼以將其屬性更改爲'A'&'C'時，我還刪除了一個具有參數'Container'對象的構造函數。

當我重新編譯這個活動並刷新它的DLL。在工作流設計器中，Activity沒有被刷新，即它的工具箱仍然指向老的dll。

去解決爲此我關閉並再次打開VS，VOILA設計師現在正在更新活動與新屬性。

這是我認爲是VS工具箱的限制，它不會刷新，儘管該DLL的活動更新。

謝謝！
