由于空引用异常,Sitecore的"链接"按钮不起作用

Question

我试图看到某个项目的链接项目.我在客户端的内容管理服务器上执行此操作.当我点击导航 - >链接时,没有任何反应.我在JavaScript控制台中收到此错误:

http://sitename.local/sitecore/shell/default.aspx？xmlcontrol = Gallery.Links& ... de-DE&vs = 1&db = master&sc_content = master&ShowEditor = 1&Ribbon.RenderTabs = true

无法加载资源:服务器响应状态为500(内部服务器错误)

这是我在Sitecore日志中看到的内容:

38424 19:09:30 ERROR Application error.

   at Sitecore.Shell.Applications.ContentManager.Galleries.Links.GalleryLinksForm.OnLoad(EventArgs e)

ownerItem创建项目字段时,参数看起来像是null.

这发生在几个不同的项目上 - 例如模板和子布局.

是什么导致了这个问题,我该如何解决？

此问题已在Sitecore中注册为错误,并且已在Sitecore 8.1更新2中修复,作为从7.2更新6合并的修补程序的一部分:"包括Sitecore 7.2 update-6中的所有相关修补程序"

https://dev.sitecore.net/Downloads/Sitecore%20Experience%20Platform/Sitecore%2081/Sitecore%20Experience%20Platform%2081%20Update2/Release%20Notes

"452241:如果存在跨数据库链接,则链接对话框失败" https://sdn.sitecore.net/Products/Sitecore%20V5/Sitecore%20CMS%207/ReleaseNotes/ChangeLog.aspx

要解决Sitecore 8.1 update 1中的问题,请安装以下补丁:

1. 将附加的Sitecore.Support.452241.dll文件放入解决方案的bin文件夹中.
2. 替换Website\sitecore\shell\Applications\Content Manager\Galleries\Links\Gallery Links.xml对话框中的以下字符串:

     <CodeBeside Type="Sitecore.Shell.Applications.ContentManager.Galleries.Links.GalleryLinksForm,Sitecore.Client"/>

用新的:

     <CodeBeside Type="Sitecore.Support.Shell.Applications.ContentManager.Galleries.Links.GalleryLinksForm,Sitecore.Support.452241"/>
