Why I receive this strange 'ExceptionHandlerFactory' issue on jboss-7? - jsf-2

Question

I want to migrate an existing icefaces application into jboss server 7 but I receive this exception:
15:01:27,399 SEVERE [javax.enterprise.resource.webcontainer.jsf.config] (MSC ser
vice thread 1-2) Critical error during deployment: : com.sun.faces.config.Config

I am simply stuck 'cause I don't know how to solve this.
Does anybody have a clue?
I have javax.faces.jar in my lib directory of ear but seems that removing it does not help (I receive a lot of other exceptions).
UPDATE: If I add this to web.xml:
<context-param>
<param-name>org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL</param-name>
<param-value>true</param-value>
</context-param>
the error seems to be gone, but another one appears:
