This.domNode is null

I am trying to use jquery to load a dojo chart. I am using this code. However in the second click, in the first button i get this error. The same occurs if i click in the first button, click in the second and click again in the first. This problem is Driving me crazy.

demo here

<script type="text/javascript">
$(document).ready(function () {
    $('.lista_').click(function () {
        $.get('index1.php', function (data) {
            dojo.addOnLoad(function () {
                require(["dojo/_base/xhr", "dojo/parser", "dojo/dom"], function (xhr, parser, dom) {
                    var um = [];
                    dijit.registry.filter(function (w) { //problem here, maybe this code destroy something that should not be destroyed
                        if (dojo.indexOf(um)) {



I can’t seem to duplicate this problem with Google Chrome 16 or Internet Explorer 9.
Is it just a certain browser that you’re having this issue with?

thanks, the problem is now solved. I need to import a css file.
