      Description

      I am reading The Java EE 7 Tutorial from http://docs.oracle.com/javaee/7/tutorial/doc/jsf-facelets005.htm#GIQZR

      After I typed the example code in the chapter 8.5 Composite Components in my IDE and run the example on GlassFish4.0, I got an error.

      java.lang.NullPointerException
      at java.util.concurrent.ConcurrentHashMap.putIfAbsent(ConcurrentHashMap.java:1078)
      at com.sun.faces.util.Cache.get(Cache.java:116)
      at com.sun.faces.application.view.FaceletViewHandlingStrategy.getComponentMetadata(FaceletViewHandlingStrategy.java:237)
      at com.sun.faces.application.ApplicationImpl.createComponent(ApplicationImpl.java:951)
      at javax.faces.application.ApplicationWrapper.createComponent(ApplicationWrapper.java:648)

      Then I check the older version of this tutorial, I found a difference in email.xhtml code. The namespace has been changed from Java EE 7. After I changed the namespace back to JavaEE 6 version, it works.

      Java EE 7

      xmlns:composite="http://xmlns.jcp.org/jsf/composite"

      Java EE 6

      xmlns:composite="http://java.sun.com/jsf/composite"
