Primefaces Snapshot 4.0 java.lang.NoClassDefFoundError: org/primefaces/component/menuitem/MenuItem

Question

I tested primefaces-4.0-20130907.101718-6.jar with tomcat Server Open Source Edition 8.0 rc1 and javax.faces-2.2.3.jar. I get this exception:

java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: Source Document: /WEB-INF/lib/primefaces-extensions-1.0.0-20130720.041214-62.jar!/META-INF/faces-config.xml Cause: Class 'org.primefaces.extensions.component.masterdetail.MasterDetailRenderer' is missing a runtime dependency: java.lang.NoClassDefFoundError: org/primefaces/component/menuitem/MenuItem

What is wrong?

Thank you

Clearly the extensions version you have is not compatible with PrimeFaces Core version you have.
