Hi Anu,
the <x:saveState> has nothing to do with your problem.
The code snippets i have written in
http://wiki.apache.org/myfaces/Tree2
works perfectly for me to lazy load the tree nodes.
Note that my backer beans are in the "session" scope,
configured in WEB-INF/examples-config.xml.
You may, at a later development stage, miss the browser-back-button
functionality.
You press 'BACK' and the navigation
of the previous page (from browser cache) does not work,
than <x:saveState> comes into the game.
Put your backer beans now in the "request" scope
and declare them with
<x:saveState id="navigationBacker_Save" value="#{navigationBacker}" />
<x:saveState id="stindexScrollerList_Save"
value="#{stindexScrollerList}" />
...
in your jsp page, and all is well :-).
See http://wiki.apache.org/myfaces/How_JSF_State_Management_Works

Marcel
