今天我根据http://sdllivecontent.sdl.com/上的文档安装了 Tridion UI 。除了“更新预览”功能外，一切似乎都在工作。对组件进行更改后，页面正确显示预览已过期，但单击“更新预览”按钮会重新加载页面，除了显示相同的警告“此页面的预览不是最新的” ”。
我看到有另一篇与此相关的帖子（Tridion New UI Preview Site 没有反映更改，除非发布）但我没有使用任何虚拟目录。
我已经解决了我在日志中发现的警告和错误，只留下一个警告（在部署程序和登台站点上）：
2012-07-05 19:44:25,085 WARN AmbientDataContext - 没有当前环境数据上下文 - 环境数据框架未正确初始化
启用调试日志记录后，我看到 AmbientDataContext 只是默认为 com.tridion.ambientdata.web.WebContext 我认为这是正确的吗？
有时，会显示会话清理错误 - 但不确定这是否与问题有关：
