grails elfinder plugin: preview does not work

Question

After several hours of digging finally got the desired result.

Problem is with the order of js inclusion. Following is my working gsp page

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/smoothness/jquery-ui.css"/>
    <link rel="stylesheet" type="text/css" href="http://elfinder.org/demo/css/elfinder.min.css"/>
</head>

<body>
    <div id="elfinder"></div>

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js"></script>
    <script src="http://elfinder.org/demo/js/elfinder.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            var elf = $('#elfinder').elfinder({
                url: '${g.createLink(controller: 'elfinderConnector')}'
            }).elfinder('instance');
        });
    </script>
</body>
</html>
