【问题讨论】：

标签： jsf richfaces seam facelets

【解决方案1】：

这是 Facelets 的错误，已在新版本中修复。您使用的是哪个版本的 facelets？

Here's some info

Facelet Bugtracker

【讨论】：

我正在使用 facelets 版本 1.1.15.B1 和 Seam 2.2。不过，不确定与 Seam 2.2 兼容的新版 facelets 是什么。
只需在facelets jar的MANIFEST文件中查看即可

【解决方案2】：

部署新的EAR 或war 时，该机器的时间设置与部署应用程序的服务器的时间设置不同，可能会刷新JSF 组件。

日志将显示以下错误。

原因是，每当发出新请求时，服务器会在将来的时间戳中看到该页面已修改并再次开始编译。这会导致组件树被重新创建，导致丢失组件存储的所有状态。

要解决此问题，请将 facelets.REFRESH_PERIOD 添加到 web.xml

REFRESH_PERIOD 表示，当请求页面时，编译器应检查更改的时间间隔（以秒为单位）。如果您不希望编译器在编译页面后检查更改，则使用值-1。设置较短的刷新周期有助于在开发过程中编辑正在运行的应用程序中的页面。

web.xml，应该是这个样子，

<context-param>
<param-name>facelets.REFRESH_PERIOD</param-name>
<param-value>-1</param-value>
</context-param>

-1表示不检查更改，因为生产服务器设置此值是安全的。
