visual-studio-2010 - Visual Studio 2010/SharePoint 2010 工作流错误

Question

我在 VS 2010 中创建了一个简单的工作流。它所做的是为一个人创建一个任务，当这个人将任务状态更改为“完成”时，它会在工作流历史记录中记录一条消息。

当我将状态更改为完成时，它说: “xxxx(工作流名称)中发生错误”。

代码:

using System;
using System.ComponentModel;
using System.ComponentModel.Design;
using System.Collections;
using System.Drawing;
using System.Linq;
using System.Workflow.ComponentModel.Compiler;
using System.Workflow.ComponentModel.Serialization;
using System.Workflow.ComponentModel;
using System.Workflow.ComponentModel.Design;
using System.Workflow.Runtime;
using System.Workflow.Activities;
using System.Workflow.Activities.Rules;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Workflow;
using Microsoft.SharePoint.WorkflowActions;

namespace WorkflowProject2.Workflow1
 {
 public sealed partial class Workflow1 : SequentialWorkflowActivity
 {
     public Workflow1()
     {
         InitializeComponent();
     }

    public Guid workflowId = default(System.Guid);
     public SPWorkflowActivationProperties workflowProperties = new SPWorkflowActivationProperties();

    private void onWorkflowActived(object sender, ExternalDataEventArgs e)
     {

    }

    public Guid taskID = default(System.Guid);
     public SPWorkflowTaskProperties taskProperties = new Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties();
     private bool taskHasCompleted = false;

    public SPWorkflowTaskProperties taskAfterProperties = new Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties();
     public SPWorkflowTaskProperties taskBeforeProperties = new Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties();
     public String taskOutcome = default(System.String);
     public Guid TaskStatusFieldID = new Guid("c15b34c3-ce7d-490a-b133-3f4de8801b76");  

    private void createTask1_MethodInvoking(object sender, EventArgs e)
     {

        taskID = Guid.NewGuid();
         taskProperties.AssignedTo = "spdev\\lzhang";
         taskProperties.Description = "Please review";
         taskProperties.Title = "Leave application";

    }

     private void completeTask1_MethodInvoking(object sender, EventArgs e)
     {
         // Finalize the task:
         taskAfterProperties.PercentComplete = 100;
         taskOutcome = "Completed";
     }

    private void notComplete(object sender, ConditionalEventArgs e)
     {
         e.Result = !taskHasCompleted;    // **(A)**
     }
     private void onTaskChanged1_Invoked(object sender, ExternalDataEventArgs e)
     { 
        string taskStatus = taskAfterProperties.ExtendedProperties[TaskStatusFieldID].ToString();

        if (taskStatus == "Completed")
         {
             taskHasCompleted = true;     // **(B)**

        }

    }

}
 }

我觉得 (A) 或 (B) 肯定有问题，但我不知道如何解决。我在 14/LOGS 文件夹中的日志文件中没有发现任何错误...

我感谢任何帮助!谢谢!

Answer 1

我在 Visual Studio 和工作流方面遇到的问题很少，其中大部分是由于没有分配正确的任务 id 或忘记为任务更改后的属性或相关 token 或其他小事情创建。

所以你面临的问题似乎属于这一类，而不是背后的代码有问题。

尝试使用本指南并确保完成每一步:http://dotnetadil.wordpress.com/2012/05/29/sharepoint-foundation-2010-visual-studio-approval-workflow/

或者甚至更好的 Microsoft 分步指南:

我会尝试的另一件事是创建您的工作流程并确保退出条件设置为 true，以便您可以检查结构是否正确完成
