Flex menu control : add custom icon in actionscript
===

I'm looking for a way to add custom icon to a Menu control.
The icons are not embedded and would like to take them from the web site.
In actionscript, when I do build the menudata, the code looks like:

    var menuData:Array;
    var menui:Object = new Object();
    menui.label = "Test Label";
    menui.enabled = "true";
    ...
    menui.icon = "http://www.example.com/test.png";
    
    var cmenu:Menu = Menu.createMenu(null, menuData);


It doesn't work. I tried with a custom itemrenderer and with IconUtility without success.
