依赖查找字段不支持关系
本文关键字：关系 不支持 字段 查找 依赖 | 更新日期: 2023-09-27 18:24:52
在使用Visual Studio 2012构建和部署的SharePoint 2010项目的功能激活过程中，我收到以下错误：
A dependent lookup field does not support relationships
我对功能文件中列出项目的顺序做了一些调整。在我正在安装的十几个列表定义和我正在创建的每个列表的一个实例中，在错误停止激活之前查看实际创建的内容表明问题可能与特定列表有关。该列表将与另一个列表建立链接列表关系。根据列表实例在要素文件中的放置顺序，相关列表可能存在，也可能在错误发生时存在。
但是，在执行我的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。所有这些都是通过代码完成的，而在声明性XML中没有。此外，该错误发生在调用功能激活的事件处理程序之前。
有什么建议吗？你知道是什么导致了这个错误吗？我是否也应该查看其他列表？
在它的声明性XML中，可疑列表有一个多查找字段要链接，链接表上有零到多个子元素。它以前已经使用此字段进行了部署和激活，所以如果它现在引起问题，我会感到惊讶——尽管使用SharePoint。。。

在对列表进行了一些处理之后，我注释掉了这一行以及内容类型Elements.xml和listSchema.xml文件中的相关字段引用。

尽管这个多值查找列的存在以前没有导致部署或激活错误，但它的删除修复了导致我提出问题的激活错误。如果我仍然需要有问题的列，我会在FeatureActivation事件中使用代码添加它。
我猜，在我以前的部署中，这两个列表已经存在，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这些列表。因此，当激活该功能时，所有先决条件对象都已存在。请参阅我的另一个问题，了解我的预部署脚本存在的问题，以及为什么这些列表没有自动取消链接：无法在visual studio预部署脚本中加载SharePoint powershell cmdlet
