public class ViewHandlerImpl

extends javax.faces.application.ViewHandler

Custom ViewHandler implementation that adds features specific to the Struts-Faces Integration Library. It leverages the "decorator pattern" customization strategy that JSF supports, by delegating most processing to the ViewHandler instance handed to our constructor.

Field Summary

private javax.faces.application.ViewHandler	handler The ViewHandler instance that we are decorating.
private static org.apache.commons.logging.Log	log The Log instance for this class.
