AS3: static vars and on-stage MC's

Question

hi,
my basic problem is as follows:
i have one swf which loads another one. both of them have
document class.
i want to access a variable of the main swf's class from the
inner swf's
class, so i turned that var into static. it works fine, as
long as i don't
access MC's on the main swf's stage from its class. i've
tried to solve it
using the 'ApplicationDomain' but it still fails.
for testing purposes i've made 2 swf's - 'main.swf' and
'inner.swf', where
on the main's stage i've placed a button, with instance name
'myBtn'.
this is the main's class:
package {
import flash.display.MovieClip;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.system.*;
import flash.events.*;
public class MainClass extends MovieClip {
private static var myStatic:String = "abc";
private var ldLoader:Loader;
public function MainClass(){
loaderInfo.addEventListener(Event.INIT, myOnInit);
private function myOnInit(eEvent){
ldLoader = new Loader();
var urlRequest = new URLRequest("inner.swf");
var context:LoaderContext = new LoaderContext (false,
ApplicationDomain.currentDomain);
ldLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
completeHandler);
ldLoader.load(urlRequest, context);
this.myBtn.addEventListener(MouseEvent.MOUSE_UP,btnUp);
private function btnUp(evt){
trace("btn up");
private function completeHandler(evt){
var inner = this.addChild(evt.target.content);
inner.myOnInit();
static function get staticVar():String{
return myStatic;
this is the inner's class:
package {
import flash.display.MovieClip;
public class InnerClass extends MovieClip{
public function InnerClass(){}
public function myOnInit(){
trace(MainClass.staticVar);
when i compile 'inner' i get the following error:
1119: Access of possibly undefined property myBtn through a
reference with
static type MainClass.
the only way to avoid this error is to comment the last line
of the
'myOnInit' function in the main class, however then there's
no access to the
main's MC's.
any solution?
thanks in advance,
eRez

Hi,
can you give us a bit of code ... that will help. And did you
declare your movieClip before (and outside of) the constructor?
Like this i mean:
class RandImg{
private var mcDefault:MovieClip; // --> here it is ..
mcDefault
public function RandImg(){ // --> cunstructor
trace("mcDefault path = " + mcDefault);
If mcDefault is not declare before and outside your
constructor, its impossible for your class to access it. Of course
you are probably aware of that .. but im trying to figure out what
can be the problem .. just guessing.
So please give us some code and we will try to help!
