          extended by org.apache.myfaces.view.facelets.el.LocationValueExpression
All Implemented Interfaces:

Direct Known Subclasses:

public class LocationValueExpression
extends javax.el.ValueExpression
implements FacesWrapper<javax.el.ValueExpression>, Externalizable

A ValueExpression that contains the original ValueExpression and the Location of the facelet file from which the ValueExpression was created. This is needed when the current composite component (cc) has to be resolved by the ValueExpression, because #{cc} refers to the composite component which is implemented in the file the ValueExpression comes from and not the one currently on top of the composite component stack. This ValueExpression implementation passes through all methods to the delegate ValueExpression, but saves the related composite component in a FacesContext attribute before the invocation of the method on the delegate and removes it afterwards.
