推荐答案
在第一个Mojarra版本2.2.0和2.2.1中，如何处理新的xmlns.jcp.org XML名称空间.除其他外，他们忽略了正确注册新的JSF 2.2组件/标签/属性/处理程序的方法.根据 issue 2900 在Mojarra 2.2.2中已对其进行了修复(注意:发行票证描述了问题症状有所不同，但在本质上，原因是相同的.)
The way how the new xmlns.jcp.org XML namespaces are been handled is broken in the first Mojarra releases 2.2.0 and 2.2.1. Among others, they overlooked to properly register the new JSF 2.2 components/tags/attributes/handlers. It has been fixed in Mojarra 2.2.2 as per issue 2900 (note: issue ticket describes different problem symptom, but under the covers, it's essentially the same cause).
因此，至少升级到Mojarra 2.2.2应该可以解决您的问题.目前已经是2.2.5版的 .
So, upgrading to at least Mojarra 2.2.2 should fix your problem. It's currently already at 2.2.5.
