我已经恢复到PrimeFaces 5.2，现在可以启动并运行该应用程序.
I have reverted back to PrimeFaces 5.2 for now do get the application up and running.
我该如何解决此问题?
推荐答案
我有完全相同的错误消息.问题是我的WAR中仍然有旧的primefaces-5.2.jar(在我的情况下是Maven提起的).在清理了整个项目之后，问题就消失了.
I had the exact same error message. The problem was that there still was the old primefaces-5.2.jar in my WAR (pulled in by Maven in my case). After cleaning the whole project the problem was gone.
因此，请确保项目或部署中的某个位置没有隐藏较旧版本的Primefaces.
So make sure that there is no older version of Primefaces hidden somewhere in your project or deployment.
