Another 1007 Null Object reference

Hey all,

I'm getting this error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Website/frame1()[Website::frame1:19]


But the thing is, if I change the line numbers around in the website document class it still says that it's line number 19?

What's the deal with that? I'm a bit confused here!

Here is line 19

Code:

---


        import flash.display.*;

---

Here is the entire code as well:

Code:

---

package {

        import flash.display.*;
        import FluidLayout.*;
        import flash.display.Sprite;
        import flash.display.StageAlign;
        import flash.display.StageScaleMode;
        import flash.events.Event;
        import gs.*;
        import gs.easing.*;
        import fl.motion.easing.*;
        import com.greensock.*;
        import flash.text.AntiAliasType;
        import flash.text.TextField;
        import flash.text.TextFieldAutoSize;
        //import flash.text.TextFormat;
        //import greensock.*;
        import flash.events.MouseEvent;
        import flash.display.*;
        import flash.events.*;
        import flash.net.URLRequest;
        public class Website extends MovieClip {

                public function Website() {this.addEventListener("addedToStage", initVar); }
                        /* Set the Scale Mode of the Stage */
                        private function initVar(e:Event){
******** this.removeEventListener("addedToStage", initVar);
//do your variable initilization, function calls, etc.
                        stage.scaleMode=StageScaleMode.NO_SCALE;
                        stage.align=StageAlign.TOP_LEFT;

                }

        private var currentlyShowing:MovieClip=null;

                public function showModalContent(clip:MovieClip):void {
                        if (currentlyShowing!=null) {
                                removeChild(currentlyShowing);
                        }
                        currentlyShowing=clip;
                        addChild(currentlyShowing);
                }

                public function removeModalContent():void {
                        if (currentlyShowing!=null) {
                                removeChild(currentlyShowing);
                                currentlyShowing=null;
                        }

                }
       

        }

}

That error looks like it is from frame script. What code do you have on frame 1?

On one fla - the main fla..

I have:

Line 19 would be the first line.. I read where when you load an swf externally, the stage doesn't exist the same way. Is this true?

Actionscript Code:

stage.scaleMode=StageScaleMode.NO_SCALE;
stage.align=StageAlign.TOP_LEFT;

Yes, that is true. When you load a swf into another swf, the loaded swf is instantiated as an object before it is put on the displaylist. This means that properties like root and stage are null until it has been added to the stage.

If those lines are in your loaded swf, it would cause the error.

I was looking at the document class the entire time, like why isn't this changing?

So, I guess it has to deal with the fullscreenEvent

Actionscript Code:

//FullScreen
stage.scaleMode=StageScaleMode.NO_SCALE;
stage.align=StageAlign.TOP_LEFT;

stage.addEventListener(Event.RESIZE, resizeHandler);


//function to handle background image resize.
function setBackground() {
    //var reg2 = stage.stageWidth / 2;
    //var reg1 = stage.stageHeight / 2;
    //bg_mc.x = reg2;
    //bg_mc.y = reg1;
    bg_mc.width=stage.stageWidth;
    bg_mc.height=stage.stageHeight;
    bg_mc.scaleX <= bg_mc.scaleY ? (bg_mc.scaleX = bg_mc.scaleY) : (bg_mc.scaleY = bg_mc.scaleX);
    musictxt_mc.x=stage.stageWidth-musictxt_mc.width*1.5;
    fullscreentxt_mc.x=stage.stageWidth-fullscreentxt_mc.width*4;
    bottomrightmints_mc.x=stage.stageWidth-bottomrightmints_mc.width;
    bottomrightmints_mc.y=stage.stageHeight-bottomrightmints_mc.height;

}
setBackground();

function resizeHandler(event:Event):void {
    setBackground();
}
//

If that is framescript in the fla which uses Website as a document class, then just delete those lines. You've already got them in the initVar function in Website.as.

If that code is for a different class or no document class, then you might want to put it inside a listener for ADDED_TO_STAGE.

It is also not really recommended that a loaded swf manipulate stage properties, since there is only one stage. If a loaded swf changes properties, it will stomp on anything that the loading swf has already done.

I think i'm getting closer here..

Actionscript Code:

if(stage != null) {
    init();
}

addEventListener(Event.ADDED_TO_STAGE, init);

function init(event:Event = null):void {
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT
stage.addEventListener(Event.RESIZE, resizeHandler);
}

/*
//FullScreen
stage.scaleMode=StageScaleMode.NO_SCALE;
stage.align=StageAlign.TOP_LEFT;

stage.addEventListener(Event.RESIZE, resizeHandler);
*/

//function to handle background image resize.
function setBackground() {
    //var reg2 = stage.stageWidth / 2;
    //var reg1 = stage.stageHeight / 2;
    //bg_mc.x = reg2;
    //bg_mc.y = reg1;
    bg_mc.width=stage.stageWidth;
    bg_mc.height=stage.stageHeight;
    bg_mc.scaleX <= bg_mc.scaleY ? (bg_mc.scaleX = bg_mc.scaleY) : (bg_mc.scaleY = bg_mc.scaleX);
    musictxt_mc.x=stage.stageWidth-musictxt_mc.width*1.5;
    fullscreentxt_mc.x=stage.stageWidth-fullscreentxt_mc.width*4;
    bottomrightmints_mc.x=stage.stageWidth-bottomrightmints_mc.width;
    bottomrightmints_mc.y=stage.stageHeight-bottomrightmints_mc.height;

}
setBackground();

function resizeHandler(event:Event):void {
    setBackground();
}

Still getting the error? I think it should be fixed.

You shouldn't need the if statement. Just putting the event listener on should be sufficient.

I'm still getting A error:

I commented out ALOT in the class..

Yeah, you are executing setBackground before it has been added to the displaylist, so stage is null.

Move the call to setBackground() into the ADDED_TO_STAGE listener.

move line 55?

No, line 52. The one that is executed immediately.
