Starling cannot access a property or method of a null object reference - actionscript-3

Question

Hey any help appreciated i've been mind boggled by the asset manager for a couple of days
Here is my Hawaii class that I'm trying to reference assets from my asset manager class (MapAssetLoadQeue). and I'm getting the Cannot access a property or method of a null object reference. Error, the error is thrown in my Hawaii class if I don't (Null) the Asset Manager reference, and it is thrown in my Loader Class haw.showHawaii()
Thanks!!!
package Maps
{
import flash.filesystem.File;
import Enqueue.MapAssetLoadQeue;
import starling.animation.IAnimatable;
import starling.animation.Juggler;
import starling.core.Starling;
import starling.display.Image;
import starling.display.MovieClip;
import starling.display.Sprite;
import starling.events.Event;
import starling.textures.Texture;
import starling.textures.TextureAtlas;
import starling.utils.AssetManager;
public class Hawaii extends Sprite
{
public var mal:MapAssetLoadQeue = new MapAssetLoadQeue;
public var Ocean:Image;
public function Hawaii():void{
super();
this.addEventListener
(starling.events.Event.ADDED_TO_STAGE, showHawaii);
}
public function showHawaii(e:Event):void{
if(mal.mapAssets != null) {
Ocean = new Image(mal.mapAssets.getTexture("blue"));
addChild(Ocean);
Ocean.x = 0;
Ocean.y = 0;
}
}
Here is my loader class where I load my assets, and here is where I get my error. haw.showHawaii(null) function. Cannot access a property or method of a null object reference.
package Assets {

// Load WorldMap asset function
public function mapLoader(): void {
mal.requestWM();
addChild(loaderMovie);
loaderMovie.x = 347;
loaderMovie.y = 277;
loaderMovie.play();
Starling.juggler.add(loaderMovie);
}
public function mapLdr(){
loaderMovie.visible = true;
addChild(loaderMovie);
loaderMovie.x = 347;
loaderMovie.y = 277;
loaderMovie.play();
Starling.juggler.add(loaderMovie);
}
//this function resizes the loader to original size and places at the bottom corner
public function resizeLdr(){

loaderMovie.x =1237;

}
public function callLoad(): void {
public function callHawaii(): void {
trace(" Hawaii is being runned");
//mal.mapAssets.verbose = true;
mal.mapAssets.loadQueue(function onGo(ratio: Number): void {
trace("Hawaii percentage is", ratio);
if (ratio == 1.0) {
Starling.juggler.delayCall(function (): void {
loaderMovie.visible = false;
//addChild(haw.Ocean);
// addChild(haw);
trace("this is haw value",haw);
//trace("this is the function", haw.showHawaii(null));
haw.showHawaii(null);
}, 0.30);
}
});
}
public function showMap() {
// get texture by name
addChild(mal);
mal.accesMap();
mal.hawaii.addEventListener(Event.TRIGGERED,removeMap);
}
// this code removes the HawaiiMap from the screen and goes directly to the wave
public function removeMap(){
trace("function initated");
mapLdr();
resizeLdr();
mal.mapAssets.purge();
mal.requestHawaii();
callHawaii();
mal.hawaii.removeEventListener(Event.TRIGGERED,removeMap);
}
public function Loader() {
super();
}
}
}
And here is my Asset Manager class
package Enqueue {
import flash.filesystem.File;
import Assets.MapAnimate;
import Assets.MapAssets;
import Maps.Hawaii;
import starling.animation.IAnimatable;
import starling.animation.Juggler;

import starling.animation.Tween;
import starling.core.Starling;
import starling.core.starling_internal;
import starling.display.Button;
import starling.display.Image;
import starling.display.MovieClip;
import starling.display.Sprite;
import starling.events.EnterFrameEvent;
import starling.events.Event;
import starling.textures.Texture;
import starling.textures.TextureAtlas;
import starling.utils.AssetManager;
public class MapAssetLoadQeue extends Sprite {
public var mapAssets: AssetManager;
public function MapAssetLoadQeue() {
super();
}
public function requestHawaii():void {
// mapAssets.verbose =false;
// mapAssets = new AssetManager;
var appDir:File = File.applicationDirectory;
mapAssets.enqueue(appDir.resolvePath("IslandMaps/Hawaii"));
//mapAssets.enqueue(Hawaii);
mapAssets.verbose = true;
}

If this is all of your code, and if I'm not missing something obvious, I don't see you creating "haw" anywhere. That is, you don't appear to have anything such as...
haw = new Hawaii();
...so, it would be null!
