Problem in setting view root in beforeRenderResponse()

Hi,
I am developing an application in which a JSF page - pageA.jsp, has a backing bean PageA.java. pageA.jsp has an <f:phaseListener > tag . PageA.java implements PhaseListenerand has got the follwoing code in beforeRenderResponse() method :

public void beforePhase(PhaseEvent e){

if(e.getPhaseId().equals(PahseId.RENDER_RESPONSE))
beforeRenderResponse();


}

public void beforeRenderResponse(){
(FacesContext.getCurrentInstance().setViewRoot(
(HttpSession)
( FacesContext.getCurrentInstance().getExternalContext().getSession(true)
)
.getAttribute("savedViewOfPageB")
);
}

The "savedViewOfPageB" label is mapped to the UIViewRoot instance of another JSF page - pageB.jsp. And it is saved in an action method called in pageB's Backing Bean, when a command button is clicked in pageB.jsp. As well as there is navigation from pageB to pageA.

So now there Navigation pageB==>pageA & the view root of pageB is saved on session which has got to be displayed as soon as the rendering of pageA takes place.

But the view root of pageA does not get changed(to that of pageB) on initial request. If I make a postback on pageA then the new view(that of pageB) gets rendered. How can I change the view root of pageA to that of pageB in beforeRenderResponse
