Tree2 Link Problems

[FSchaare]

Hi,

i'm trying to understand the tree2 component, which is a bit difficult 
for me.

I have the tree2 component working in the left frame of a frameset. When 
the user hits a document node, a refering URL should be loaded in the 
right frame. How do i do that with tree2 ?

I store the URL information in node.id. Is that the correct place for it ?

Is the any Documentation about the tree2 component ?

thanks for your answers.
