Sounds like a problem with faces-config.xml (something to do with the faces-config element). Here's an example that works:
<?xml version='1.0' encoding='UTF-8'?>
<!-- =========== FULL CONFIGURATION FILE ================================== -->
<faces-config version="1.2"
              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_1_2.xsd">
  <application>
    <locale-config>
      <default-locale>en_GB</default-locale>
      <supported-locale>en_GB</supported-locale>     
    </locale-config>
  </application>
  <managed-bean>

    <managed-bean-class>com.test.Bean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
  </managed-bean>
</faces-config>
