Affects: Release Notes
Workaround: Workaround Exists
Workaround Description: Workaround involves removing JSF implementation from the application server. 

Struts applications using the MyFaces context listener do not work on the Enterprise Application Platform, or the Enterprise Web Platform. A workaround is to remove the JSF jars from the $JBOSS_HOME/server/<Profile>/deploy/jbossweb.sar/jsf-libs/*.jar directory, and to comment the following lines out of the $JBOSS_HOME/server/<Profile>/deployers/jbossweb.deployer/web.xml.

<context-param>
     <param-name>com.sun.faces.injectionProvider</param-name>
     <param-value>org.jboss.web.jsf.integration.injection.JBossInjectionProvider</param-value>
</context-param>

<listener>
     <listener-class>org.jboss.web.jsf.integration.config.JBossJSFConfigureListener</listener-class>
</listener>

<listener>
     <listener-class>com.sun.faces.application.WebappLifecycleListener</listener-class>
</listener>

<init-param>
     <description>JSF standard tlds</description>
     <param-name>tagLibJar0</param-name>
     <param-value>jsf-libs/jsf-impl.jar</param-value>
</init-param>
<init-param>
     <description>JSTL standard tlds</description>
     <param-name>tagLibJar1</param-name>
     <param-value>jstl.jar</param-value>
</init-param>

You will also need to remove or comment out the following line from $JBOSS_HOME/server/<Profile>/deploy/jbossweb.sar/META-INF/jboss-structure.xml. Note that this will remove your ability to run the admin console. 

<path name="jsf-libs" suffixes=".jar" />
