在使用Visual Studio 2012构建和部署的SharePoint 2010项目的功能激活期间，我收到此错误：
A dependent lookup field does not support relationships
我在我的功能文件中列出了项目的顺序。在我正在安装的十几个列表定义和我正在创建的每个实例中，查看错误停止激活之前实际创建的内容表明问题可能出在特定列表中。该列表将涉及与另一个列表的链表关系。根据列表实例在要素文件中的放置顺序，相关列表可能会或可能在错误发生时存在。
但是，在执行功能接收器的功能激活代码之前，不会创建与列表相关的查找字段。并且在主查找字段存在之后才会创建从属查找字段。所有都是通过代码完成的，并且在声明性XML中没有。此外，错误发生在调用功能激活事件处理程序之前。
有关寻找什么的任何建议？ 可能导致此错误的任何想法？ 我应该查看其他列表吗？
在它的声明性XML中，可疑列表有一个多重查找字段，用于链接表上的零对多子元素。它之前已经通过这个领域进行了部署和激活，所以如果它现在导致问题我会感到惊讶 - 尽管使用SharePoint ......

在对列表进行一些处理之后，我从内容类型Elements.xml和列表Schema.xml文件中注释掉了这一行和相关的字段引用。
<Field ID="{984cec2d-b1a6-4a6a-a4c7-fbbf8f30232a}" Type="LookupMulti" Name="Authorized Recipients" DisplayName="Authorized Recipients" Required="TRUE" Group="ITCO Site Columns" Mult="TRUE" EnableLookup="TRUE" IsRelationship="TRUE" ShowField="Company" List="Lists/ITCO Export Request Recipients" FieldRef="ID"></Field>
虽然这个多值查找列的存在以前没有导致部署或激活错误，但是它的删除修复了导致我的问题的激活错误。如果我仍然需要违规列，我将使用FeatureActivation事件中的代码添加它。
我猜测在以前的部署中，两个列表已经存在，并且将它们链接在一起的主查找字段阻止了Visual Studio在部署期间删除和重新创建列表。因此，当激活该功能时，所有必备对象都已存在。请参阅我的其他问题，了解我在预部署脚本中遇到的问题以及为什么这些列表没有自动取消链接：Cannot load SharePoint powershell cmdlets in visual studio pre-deployment script
