UIViewRoot not available in beforeRenderResponse phase

Question

Hi all,
I am trying to change the attribute of some of my component present in my jsf page before they get rendered. For this I have written a phaseListner which iterates through all the child components of UIViewRoot before render response phase. I can get desired component and is able to change the component attribute/property. But this works only for the page which has been posted back. If a page is transfered to a new page, I can't get the component tree of the UIViewRoot of a new page in before Render phase. But the component tree is available during the render response phase.
It is possible for me by any means to get component tree of UIViewRoot in before render response phase when page is resulted from another page.(ie. non-postback page)
Thanks for your help in advance

Answer 1

The default NavigationHandler finally invokes ViewHandler.createView().
The structure of the component tree returned by createView() is implementation dependent.
The specification says:
The UIViewRoot instance returned by the createView() method must minimally
contain a single UIViewRoot provided by the JSF implementation, which must
encapsulate any implementation-specific component management that is required.
Optionally, a JSF implementation�s ViewHandler may support the automatic
population of the returned UIViewRoot with additional components, perhaps based
on some external metadata description.
