我有两个相似的页面，一个名为 index.xhtml，一个名为 index_old.xhtml，两者都在 Web Pages 根目录中，如 NetBeans 7.1.2 中所示。
index.xhtml 处理正确并具有正确的输出。
index_old.xhtml 似乎只显示硬编码文本而没有其他内容。
当 index.xhtml --> index_older.xhtml & index_old.xhtml --> index.xhtml 时，以前不能正常工作的 index_old.xhtml 现在显示正确的输出，而以前正常工作的 index.xhtml 现在不能显示正确的输出。
为什么会这样？这个问题是如何解决的？
以下是我的索引文件：

按照 BalusC 的建议进行了更改，结果收到了错误和堆栈跟踪。请参阅下面的错误和堆栈跟踪：
