Open programmaticaly external URL (+overlay) Created Nov 11, 2009

I know how I can open external URL and how I can open programmaticaly overlays but when I mix them, I get nothing.

here is my code

<div class="overlay" id="overlay"> 
  
    <div class="contentWrap"></div> 
 
</div>
    
    <script type="text/javascript">
        $("#overlay").overlay(
        {
            effect: 'apple',
            top: 70,
            expose: 'darkred',
            onBeforeLoad: function() {
                var wrap = this.getContent().find("div.contentWrap");
                wrap.text("Loading...");
                wrap.load('http://www.google.com/');
            },
            api: true
        }).load();
       
    </script>

when I run my page.
overlay is working, preload text is visible (Loading...) but the overlay stay empty. I tried with differents URLs, but nothing is working. It's like if wrap.load was not working. I used Firebug but nothing helped :/

any help? :)
