accessing Parent Movieclip, dispatchEvent

[ziriguidum]

help! i have a menu class that creates a menu dinamically.

I want the main class (the one that loads the menu) to re- position the menu, but it has to do it after the menu is created so at this point the menu has its final width.

I ´ve told the menu to dispatch an event but the main class doesn´t listen:

// menu.as:
dispatchEvent(new Event("MENU_COMPLETED"));

// main.as:
addEventListener("MENU_COMPLETED", placeMenu);
private function placeMenu(e:Event):void
{
     trace ("hello!");    // nothing happens
}

i´ve tried to access the main class in the menu but it throws null.

// menu.as
trace (MovieClip(parent));	// throws null
trace (parent);	// throws null

please help! thanks!
