我已在本地服务器中部署Omnifaces Showcase 2.4来测试InvokeActionEventListener，因为我遇到了Flash Scope的一些问题。由于展示InvokeActionEventListener无效，我下载了一个干净的Wildfly 8.2.0并将其部署在那里，我得到了相同的结果。
基本上问题是在页面eventlisteners/InvokeActionEventListener中，当我点击演示部分中的“此链接”时，重定向发生后没有消息，尽管它在官方展示网站中正确显示。
请在下面打开“eventlisteners / InvokeActionEventListener”页面时的日志条目：

我正在使用Ubuntu 16.04。我必须采取哪些额外步骤才能在本地正确使用Omnifaces Showcase？也许服务器配置？
