J2 - Menu Navigation - Root Folder

[Shah Amit]

Hi David,
Reposing my question on the developer thread.
The problem is org.apache.jetspeed.profiler.ProfiledPageContext interface 
and all the other related interfaces are very convinient to navigate child 
elements. But it is tough to reach the "root" folder, or to traverse up the 
tree.

Now the reason I need to traverse up the tree is because I need to display a 
"tabbed" menu interface which goes 3 levels deep. Something similar to 
amazon.com. Now all the samples included in J2 display all the child folders 
and sub-elements, but there is no example that basically displays 
"everything" under pages directory in like a tree format and let user choose 
where he wants to go.

Would really appreciate any help.
For now the I am thinking of workaround where I will go 5 levels down. I 
dont think I need to worry for more than that. Also to reach the root 
folder, I am using following macro -

#macro(createTree $folder)
   #set($parent = $folder.getParent())
   #if($parent != "/")
       #createTree($parent)
   #else
       #set($folder=$parent)
   #end
#end
Thanks for all your helps,
Amit
