Class JsfManagedBeanResolver

java.lang.Object
  javax.el.ELResolver
      org.springframework.faces.webflow.JsfManagedBeanResolver

public class JsfManagedBeanResolver
extends javax.el.ELResolver

ELResolver that checks request, session, and application scopes for existing JSF-managed beans. This allows traditional JSF-managed beans (defined in faces-config.xml) to be resolved through expressions in a flow definition. The preferred approach is to instead use Spring to configure such beans, but this is meant to ease migration for users with existing JSF artifacts. This resolver will delegate to a temporary FacesContext so that JSF managed bean initialization will be triggered if the bean has not already been initialized by JSF.
