国际化中的解析异常 - 未找到消息
Parsing Exception in Internationalization - message not being found
我试图在开始开发之前将我的应用程序国际化，以便以后更容易扩展它。
然而，尽管我尝试遵循教程，但我总是遇到同样的错误：我的 xhtml 中的标签无法解析，就好像信息根本不存在一样（即使 Eclipse 自动完成它们）。
stacktrace的总结如下(Here for the full stacktrace at Pastebin):
Type Exception Report

动态网络模块是 3.1
我非常有信心将 #{msg.['title.index']}" 更改为 #{msg['title.index']}"（删除 .）会有很大帮助
