Re: [Myfaces-user] how to use TreeSelectionListener in a tree

[Bill Dudney <bd...@mac.com>]

Hi Alexandre,

Sorry that I can't answer your question but I wanted to redirect you  
to the new home of MyFaces on http://myfaces.apache.org.

I've cc'd the user list which is very active and can probably answer  
you question quickly.

Thanks for using MyFaces!

TTFN,
