Cannot child it to anything other than flash.Lib.current

[smoketh]

To example i have complex flash app built with usage of stablexUI.
From there i load specific document

package;
import ru.stablex.ui.widgets.Box;
import cocktail.api.CocktailView;
import flash.display.Sprite;

class BrowserWindow extends Box
{

    var cv:CocktailView;
    var loaded_content:Box = new Box();
    override public function onCreate():Void 
    {
        super.onCreate();
        ...
        this.addChild(loaded_content);
         }//This function called from outside right after element was created
    public function initCocktail()
    {
        cv = new CocktailView();
        cv.viewport ={ x:0, y:0, width:640, height:480 };
        cv.loadURL("embed2.html");
        //cv.rende
        cv.window.onload = function(e) 
        { 

            loaded_content.addChild(cv.root);
            //flash.Lib.current.addChild(cv.root);
        };
    }

It loads it to lib.current just fine, but i see nothing when i load it as child of box which itself is child of the multiple object tree. (tried attaching it to both Box and just Sprite.)
(tree looks like something like this desktop:Box > basicWindow:Box > thisOne:Box > cv.root)

cv.window.onload = function(e) { this.addChild(loaded_content); addChild(cv.root); var timer:Timer = new Timer(1000); timer.run = function (){loaded_content.addChild(cv.root);} //flash.Lib.current.addChild(cv.root); }; try this!

nope, nothing.
http://screencast.com/t/bibE3uAu <should be inside of about window.

I suspect it's because cocktail probably has separate update cycle and it updates graphics way before stablex does resulting in overdraw, but it doesn't explain why it shows up when i add it to the root of scene.
(adding loaded_content.refresh() and this.refresh() does nothing as well)

NEVERMIND! facepalm i completely forgot to init root box and set it's w/h elements. Please close this shameful topic.
