[jQuery] [treeview] unique: true - possible error

[Mariusz]

Based on async demo and jquery 1.3.1:

$(document).ready(function(){
                $("#black").treeview({
                   collapsed: true,
                   unique: true,
                   persist: "cookie",
                        url: "source.php"
                })
        });

Page loading makes one request for "source.php?root=source" that is
OK.
When I click on node to open then treeview makes requests for every
node on clicked level depth.
I thing it is error becouse when I set "unique: false" then click on
node makes only one request per click.
