Can't get total bitmapwidth variable while clicking first time. LocalConnection()

programming flash
1

I have two .SWFs one is loading in a parent SWF. I’m trying to pass a bitmap total width by using LocalConnection.send() method.

I can received the variable result but after clicking twice in same menu option. When first clicked I got a 0 as result. After second time, I got the right bitmap width total (ex: 1800).

I set a global var and trying to understand why it returns 0 at first click instead of 1800 dynamically supposed to return.

Does anyone know HOW to resolve that?

PS: I draw container.panelMC in main.fla

In my loadPhoto (loadPhoto.swf) class:


for (var i:uint=0;i<tabPhotos.length;i++) {
...
 bitmapWidthTotal += 900;

}

sender = new LocalConnection();
sender.addEventListener(StatusEvent.STATUS, handleStatusEvent);
sender.send("abc", "setBitmapSize", bitmapWidthTotal);

In my Main class (main.swf):


// Global var
private var testBitmap;

...
receiver = new LocalConnection();
receiver.connect("abc");
receiver.client = this;

public function setBitmapSize(bitmapWidth:uint):void
{
            this.testBitmap = bitmapWidth;
            trace("**setBitmapWidth: " + bitmapWidth);
}

private function handleMenu(event:CustomEventCenter):void
{
    menuOption = event._name.menu;
            
    menuOption.addEventListener(MouseEvent.CLICK, handleOptionClicked);
 }

private function handleOptionClicked(event:MouseEvent):void 
{
  switch(event.target.name) {
                case "menuOption1" :
                    loader.load(new URLRequest("option1.swf"));
                    container.panelMC.width = getBitmapSize(); // got 0 first click
                    trace("Option1 Width: "+container.panelMC.width);
                    scrollbarMC.resetThumbScroll(container, false);
                    break;
                 ...
 }
}

private function getBitmapSize():uint
{
            return testBitmap;
 }
