在我的本地sitecore 66安装上，当进行任何随机页面演示>详细信息>编辑控制时，第二个弹出窗口（编辑窗口）会抛出以下错误：

exception occurred during the execution of the current web request. Please review
the stack trace for more information about the error and where it originated in 
the code.
Exception Details: System.NullReferenceException: Object reference not set to an 
instance of an object.
Source Error:
An unhandled exception was generated during the execution of the current web

identified using the exception stack trace below.
Stack Trace:

有什么想法吗？

Mine sitecore升级安装从6.4升级到6.6。错误消息中的重要部分是错误位置

Sitecore.Shell.Applications.Layouts.DeviceEditor

通过比较标准sitecore 6.6安装和本地安装，我发现文件sitecore\shell\applications\layout\deviceeditor.xml已经过时。用正确的版本替换文件解决了问题。
