Question

我正在尝试以编程方式将带有新时间轴的Tasklist添加到我的解决方案中。但是它似乎与我的ContentType不兼容。 ContentType继承自任务，但必须删除字段PercentComplete，AssignedTo和Priority，并重命名DueDate和StartDate。我的内容类型如下所示：

<!--PercentComplete-->
<FieldRef ID="{d2311440-1ed6-46ea-b46d-daa643dc3886}" Hidden="TRUE" />
<!--AssignedTo-->
<FieldRef ID="{53101f38-dd2e-458c-b245-0c236cc13d1a}" Hidden="TRUE" />
<!--PreviouslyAssignedTo-->
<FieldRef ID="{1982e408-0f94-4149-8349-16f301d89134}" Hidden="TRUE"/>
<!--Priority-->
<FieldRef ID="{a8eb573e-9e11-481a-a8c9-1104a54b2fbd}" Hidden="TRUE" />

<!--Title-->
<FieldRef ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}" Required="TRUE" />
<!--LinkTitle-->
<FieldRef ID="{82642ec8-ef9b-478f-acf9-31f7d45fbc31}" />
<!--LinkTitleNoMenu-->
<FieldRef ID="{bc91a437-52e7-49e1-8c4e-4698904b2b6d}" />

<!--DueDate-->
<FieldRef ID="{cd21b4c2-6841-4f9e-a23a-738a65f99889}" DisplayName="End of Task" Required="TRUE" />
<!--StartDate-->
<FieldRef ID="{64cd368d-2f95-4bfc-a1f9-8d4324ecb007}" DisplayName="Start of Task" Required="TRUE" />

<!--Checkmark-->
<FieldRef ID="{ebf1c037-47eb-4355-998d-47ce9f2cc047}" />
<!--Body-->
<FieldRef ID="{7662cd2c-f069-4dba-9e35-082cf976e170}" />
<!--Predecessors-->
<FieldRef ID="{c3a92d97-2b77-4a25-9698-3ab54874bc6f}" />
<!--RelatedItems-->
<FieldRef ID="{d2a04afc-9a05-48c8-a7fa-fa98f9496141}" />
<!--Status-->
<FieldRef ID="{c15b34c3-ce7d-490a-b133-3f4de8801b76}" />

<!--ParentID-->
<RemoveFieldRef ID="{fd447db5-3908-4b47-8f8c-a5895ed0aa6a}" />

由于隐藏的AssignedTo，PrelyAssignedTo被隐藏。如果我不删除ParentID，功能将不会激活（抛出错误）！ Anywho，删除该字段将激活，但List会抛出错误。我很困惑。

List是一个简单的Tasklist，上面添加了contenttype（删除了标准任务），Tasklist的类型设置为171。我使用Visual Studio向导添加了List并使用向导更改了内容类型，然后转到xml并更改了类型。

这是错误讯息：

HierarchyParentKeyColumnName

通过简单地为stackoverflow制定你的问题来排序你的想法总是有帮助;）我试图用你的ParentID解决错误，以便你可以专注于真正的问题。事实证明，ParentID是真正的问题。

我添加了Lookup目标：

<!--ID-->
<FieldRef ID="{1d22ea11-1e32-424e-89ab-9fedbadb6ce1}" />
<!--ParentID-->
<FieldRef ID="{fd447db5-3908-4b47-8f8c-a5895ed0aa6a}" />

而且（更重要的是）改变了＆＃34; self＆＃34; parent contentTypes（任务）查找字段定义到实际列表实例。

<Field Type="Lookup" 
       Indexed="TRUE" 
       Name="ParentID" 
       ID="{fd447db5-3908-4b47-8f8c-a5895ed0aa6a}" 
       Hidden="TRUE" 
       Required="FALSE" 
       List="$Resources:core,lists_Folder;MyTaskList" RelationshipDeleteBehavior="Cascade" 
       ShowField="ID" DisplayName="$Resources:core,Parent_ID;" SourceID="http://schemas.microsoft.com/sharepoint/v3" StaticName="ParentID"></Field>

以编程方式定义Tasklist - ArgumentException'HierarchyParentKeyColumnName'
