Resolution:

The managed property name set in the faces-config.xml file within the <managed-property> and the <property-name> elements does not match with the JavaBean property name as in the Managed Bean class and/or with the property name in the JSF tags in the JSPs. The property name in the managed bean class, as per JavaBean conventions, must be the same as set in the faces-config.xml configuration file as well as the property name used in the JSF tags in any of the JSPs.
