A different implementation of Frank Nimphius'sADF Tree drill down example

Question

I am using this implementation of adf tree and it works ok, but my tree is different because i want to use the command link when the node has no child and not when the node is in level 2.
So i suppose i must change the TreeManagedBean when it said :
if (getTreeHandler().getDepth()==2) {
i must write if the node has child.
For example my tree is like this:
informacion
--informacion general
--- Domicilios (*)
--- fallecidos (*)
--informacion social
--- asistencia social (*)
--- salud (*)
--- patrimonio
---- autos (*)
---- aeronaves (*)
so i want these (*) nodes appears with a command link and the other with output text, but i don't know how to ask if the node has or not child.
i use this System.out.println("Childs:"+getTreeHandler().getChildCount()); but always shows me 0.
any ideas?
thanks.

Hi,
i have under my nodeStamp a commandlink with value #{node} and in rendered i type #{node.children!=null} but it shows me all the items of the tree with a link, and except the root, when and item has childs it appears not with his name instead appears with the name of the first child.... i give you an example:
This is the tree ok:
-Root
-- Nodo 1
--- item 11
--- item 12
-- Nodo 2
-- Nodo 3
--- item 31
--- item 32
--- item 33
and this what happend when i put in rendered property of commandlink: #{node.children!=null}
the tree appears like this:
-Root
-- item 11 (instead of Node 1 it shows the name of the first child)
--- item 11
--- item 12
-- Nodo 2
-- item 31 (instead of Node 3 it shows the name of the first child)
--- item 31
--- item 32
--- item 33
why is that happening?, i don't understand.... and i don't know how to do it right
if you could help me , please
thanks a lot.
