All Implemented Interfaces:

Command

public class AssignViewRootCommand
extends AbstractCommand

This Command assigns properties to an existing UIViewRoot. It can only update the renderKit and locale properties. There are two new properties on the view root in JSF 1.2, beforePhaseListener and afterPhaseListener. These two require MethodExpression that is introduced in JSP 2.1. We will have to wait until we can migrate to 1.2 before we can support these attributes. For some reason, these are not wrappered like the ValueBinding is wrapperd by the ValueExpression.
