org.springframework.faces.webflow
Class JsfManagedBeanPropertyAccessor

java.lang.Object
  org.springframework.faces.webflow.JsfManagedBeanPropertyAccessor

All Implemented Interfaces:

org.springframework.expression.PropertyAccessor

public class JsfManagedBeanPropertyAccessor
extends java.lang.Object
implements org.springframework.expression.PropertyAccessor

Spring EL PropertyAccessor 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.

Source code adapted from JsfManagedBeanResolver.
