Eclipse Kepler 不想在 ctrl 键上的 jsf 中打开 java 代码

Question

我无法做到这一点。

在以前的eclipse版本中没有这样的问题。 Erlier 当我将鼠标放在 EL 表达式上并按下 CTRL 键时 - EL 表达式带有下划线，当我点击它时 - 它把我带到了 java 代码中。

现在：在 Kepler - eclipse 中抛出异常（在错误日志中）：

Message: Unhandled event loop exception

请注意，在 JSF 中解析 el 表达式 - 当我开始编写它时，它可以正常工作。 你有什么提示吗？

好的，最后我设法解决了配置 Eclipse 项目方面的问题。
