jstree 1.0  does not work well
<p>I have a problem with the new version of jstree when using this part of code. At the first execution, the data function returns the root node. The problem is that this code never executes again. So whatever happens, I just have the root node. Does anybody know a solution?</p>

<pre><code>$('#tree').jstree(
  json_data: {
                    ajax: {
                        url: '&lt;%=url %&gt;',  
                        dataType: "json",
                        data: function (n) {
                            return {
                             "id": n.attr ? n.attr("id") : 0
                            };
                        }
                    }
                },
                themes: { url: '/ThirdParty/jquery/jsTree/themes/', theme: "default", dots: true, icons: true },
                plugins: ["json_data", "themes", "ui"]

            })
            {
</code></pre>
