Who's doing wrong is me :'(, I promise to create a documentation.
You should see "example/" folder because the "example-aa-ur/" needs the project Url Rewrite ( http://www.phpclasses.org/browse/package/4231.html ).
Also if you want to use this project with php4 you need my json ajax class (http://www.phpclasses.org/browse/package/4205.html).
PD: I promise to take time to write a doc. for this class.
