Unable to fetch navigation nodes - Ajax framework customization

hi,

I am following below tutorial to create a Ajax framework page

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70bfe58d-1ed9-2d10-42b6-821d62777d6f?QuickLink=index&overridelayout=true&50599009721255

The Masthead UI part appears fine (see screnshot) but navigation nodes assigned to my id (content admin, system admin and user admin) do not appear.

The tutorial talks about executing below method for getting navigation nodes

EPCM.getSAPTop().LSAPI.AFPPlugin.model.getNavigationSubTree(null,

drawTree, sapTreeEl);

No clues why this does not fetch necessary navigation nodes for me. Please help

thank you !
