我用 PrimeFaces 写了一个页面，女巫工作正常。然后我尝试添加 PrimeFaces Mobile：

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:p="http://primefaces.org/ui"
      xmlns:pm="http://primefaces.org/mobile">
<f:view renderKitId="PRIMEFACES_MOBILE"/>

但页面未呈现，我得到一个 NullPointerException。

我错过了什么吗？

编辑：

这是堆栈跟踪：

试试这个代码：

 <html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:p="http://primefaces.org/ui"
  xmlns:pm="http://primefaces.org/mobile">
  <f:view renderKitId="PRIMEFACES_MOBILE" contentType="text/html" />

在 faces-config.xml 中：

 <?xml version='1.0' encoding='UTF-8'?>
    <faces-config version="2.0"
              xmlns="http://java.sun.com/xml/ns/javaee" 
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
              xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
              http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">

    <application>
        <resource-bundle>
            <base-name>/Bundle</base-name>
            <var>bundle</var>
        </resource-bundle>   

        <navigation-handler>
            org.primefaces.mobile.application.MobileNavigationHandler
        </navigation-handler>
    </application>

    </faces-config>
