Question

每当工作流程的2个或更多实例重新启动时，我就会遇到错误。我们在办公室的网络事件中暂停了工作流程。这是一个脚本超时，中断了进程。我无法重现此超时，因此我尝试重新启动工作流程活动以完成此过程。但是，当我重新启动超过1个挂起活动时，我收到此错误（完整日志远远低于以下）：

Cannot insert the value NULL into column 'ITEM_ID', table 'tridion_cm.dbo.ITEM_ASSOCIATIONS'; column does not allow nulls. INSERT fails.
The statement has been terminated.

重新启动活动并让它一个接一个地完成没有问题。

工作流信息

组件是由另一个应用程序通过BusinessConnector新创建的。它在完成活动之前执行修订保存。 WF的目标是

根据其他系统的文本值分配必要的组件链接;
创建页面;
并将其发布到目标。

我知道这可以通过其他方式更好地完成，但现在就是这样，请接受实施。

模型/架构

Product
    - modelName (text)
    - categoryName (text)
    - categoryCL (component link)
    - statusName (text)
    - statusCL (component link)
    - blah1 (text)
    - blah2 (text)
    - blah3 (text)
    - blah4 (text)

自动活动脚本：

' COMPONENT WORKFLOW for PRODUCT SCHEMA (START)

' Load common functions
ExecuteGlobal oTDSE.GetObject("/webdav/200%20Design/Building%20Blocks/Library/Design/Workflow/Common/Workflow%20Functions.tbbs", 1).Content

' Initialize
Set objComp = CurrentWorkItem.GetItem()
Set oContentPub = objComp.Publication
Set oWebsitePub = oTDSE.GetObject(GetStagingLangPub("EN", "website1"), 1)
modelName = objComp.Fields.Item("modelName").Value.Item(1)

' Search and Assign component links based on some text fields from BC client
Set compListRowFilter = oTDSE.CreateListRowFilter()
Call compListRowFilter.SetCondition("ShowNewItems", TRUE)
Call compListRowFilter.SetCondition("ItemType", 16)

' Assign the first component link (categoryCL)
categoryName = objComp.Fields.Item("categoryName").Value.Item(1)
Set categoryComp = GetObjectFromFolder(categoryName, oTDSE.GetObject(categoryFolderWebDav, 1), compListRowFilter)
If Not categoryComp is Nothing Then
    objComp.Fields.Item("categoryCL").Value.RemoveAll
    objComp.Fields.Item("categoryCL").Value.Add(categoryComp)
    Call objComp.Save(True)
Else
    Call SendNoObjectEmail("Category", categoryName, "categoryCL", GetEmailsFromGroup(oContentPub, categoryOwner), "")
End if

' Assign the second component link (statusCL)
statusName = objComp.Fields.Item("statusName").Value.Item(1)
Set statusComp = GetObjectFromFolder(statusName, oTDSE.GetObject(statusFolderWebDav, 1), compListRowFilter)
If Not statusComp is Nothing Then
    objComp.Fields.Item("statusCL").Value.RemoveAll
    objComp.Fields.Item("statusCL").Value.Add(statusComp)
    Call objComp.Save(True)
Else
    Call SendNoObjectEmail("Status", statusName, "statusCL", GetEmailsFromGroup(oContentPub, statusOwner), "")
End if

' Create a page with the component in WF
Set oPage = CreateDefaultPage(modelName, oWebSitePub, SaveToFolderWebDav, PageTemplateWebDav)

我没有放大到确切发生的位置，但我认为它是categoryCL或statusCL的objComp.Save(True)行。

Answer 1

我注意到您正在呼叫Call objComp.Save(True) - “True”参数强制“CheckIn”，因为它意味着“完成编辑”。

看起来这可能会发生两次（即如果有statusCL和categoryCL）可能会导致问题。我会尝试更改行为，以便在完成更改时仅在最后调用Save()方法，而不是保存两次。

Answer 2

从我看到的问题是你试图将空值分配为组件链接。你确定你没有尝试将这两个组件相互链接吗？可能是您尝试创建的链接是工作流中的新组件（它还没有签入版本），因此您无法创建指向它的链接。尝试在脚本中添加一些日志记录，这样我们就能看到它失败的确切位置以及参数是什么。

我同意弗兰克的看法，这个例外值得一个缺陷报告。
