Issue fixed when I added dependency to JSF 2.2.8 in jboss-deployment-structure.xml file in the EAR META-INF/ directory that contains the following data:

<sub-deployment name="sample.war">

        <exclusions>

            <module name="javax.faces.api"/>

            <module name="com.sun.jsf-impl"/>

        </exclusions>

        <dependencies>

            <module name="javax.faces.api" slot="2.2"/>

            <module name="com.sun.jsf-impl" slot="2.2"/>

        </dependencies>

    </sub-deployment>
