Tridion UI - 预览不更新

Question

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 is not reflecting with the changes unless pulished)，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（在部署程序和暂存站点上）：

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

启用调试日志后，我看到 AmbientDataContext 只是默认为 com.tridion.ambientdata.web.WebContext，我认为这是正确的？

有时会显示会话清理错误 - 但不确定这是否与问题有关：

任何帮助将不胜感激？不知道还能尝试什么。

谢谢

问题是发布属性中的“发布路径”和“发布 URL”值不正确。恢复到默认值后，它现在可以工作了 - 非常感谢 Tridion PS。

发生该错误是因为 UI 每次在页面或内容发生更改或按下“更新预览”按钮时创建的临时文件未创建，因此当它尝试删除它们时会向您显示该错误。所以，这个错误更像是其他错误的征兆，而不是错误本身。您需要检查的是这些临时文件是否已创建。

文档的这一部分 (http://sdllivecontent.sdl.com/LiveContent/content/en-US/UIU4SDLT2011SP1/task_89D69D4B67C340388652DEAECA6B5B79) 介绍了会话预览的设置。

您似乎错过了配置此部分的一些步骤。
