Maybe you could school me in how to keep null object references out of complex Classes?
I have function init, which runs on the creationComplete of the application. The init calls get_login_share_object funtion, in which objects are created, which are null.
Now my problem is that, I get a null object reference error on the Alert in "init()". How can I avoid that. Is it possible that I can have a check to see, if the objects are null the program should just skip reading the objects.
private function init():void
{
var stored_credentials:Object = get_login_share_object();

I changed my html template to include flashvars like so:

// if we've detected an acceptable version

Simple to understand problem, hoping for similarly easy solution:When I type in my search query, I sometimes get the "Error #1009 Cannot access a property or method of a null object reference" on the dataField = new ArrayCollection(result.data); line.

I'm new to flex and actionscript. I'm trying to create a small flex app that has multiple states, but if I have nested containers, it looks like some of the objects are not getting initialized when I expected them to be, even when I have the creationPolicy set to "all."I've reduced the issue to a small example, with a commented block showing when it does work.sing the existing code, I get this error: "TypeError: Error #1009: Cannot access a property or method of a null object reference at main/init()" and the event handlers are not installed.If I instead use the commented block, which has the Panel and VBox elements removed, it does work.I know I could add a click attribute to the mxml elements, but this is just a simplified example, and I'm more interested knowing why the objects are not initialized when the app loads.

I run my code, it will give me a "Cannot access a property or method of a null object reference" error. I double checked, I realized when the program run until the component file up to the accessing dataGridData variable, that dataGridData variable is null at that time. That is probably flex initiate the component file before it send or get the xml data from server in main. Which cause the variable is still null at the mean time.
I have this custom class which extends EventDispatcher
private var assetsManager:AssetManager;
And this running on creationComplete
GeneralUtils.parentComponent = this;
this.assetsManager.addEventListener(AssetEvent.ASSETS_LOADED,OnAssetsLoaded);
this.LoadConfigFile();
I'm getting 1009 errors on the second line. I've been looking at this for a while and can't figure out what it can't find. The OnAssetsLoaded function is there.
There are a three public variable

I'm creating a movie clip button and for the out state I have this:
web_btn.addEventListener(MouseEvent.MOUSE_OUT, at_out);
function at_out(event:MouseEvent):void {
web_btn.gotoAndPlay(30-(web_btn.currentFrame-11));
[code].....
On the stage there's an empty clip called mc1in the library there's a clip called with the class name Ballnow every frame this functions is executed:mc1.addChild(new Ball())inside ball, at frame ten:this.parent.removeChild(this)so this creates a bunch of balls on the stage, but after a while this error shows up:TypeError: Error #1009: Cannot access a property or method of a null object reference.t Ball/frame10()Edit: ok by tracing Ball's name I understand that even though the Ball is removed it continues to exist somewhere?
View 3 RepliesWhy does this code not work? It seems to make the error:#1009: Cannot access a property or method of a null object reference. my buttons on the same frame have all stopped working,
import flash.display.MovieClip;import fl.containers.ScrollPane;scrollpane.content as MovieClip;MovieClip(scrollpane.content).gotoAndSto p("frameName");
I'm animating some mc's at the beginning of the timeline with AS3 (mostly alpha fades), but then I have some tweened animations further down the timeline and a "naviagation bar" that's on all frames, so a user can click a button and jump to a part of the timeline to see some other animations.My problem is that if I don't wait to see the programmed animations at the beginning and just clicka button to see the other tweened animations, I get an error:
"Error #1009: Cannot access a property or method of a null object reference. at flash_fla::MainTimeline/tube_glow2_animate()"

My movieclips are being nulled when moving between scenes, they are created on the stage and accessed through as3. I have login screen with three button, one logout, one exits the system and the other takes them to the next scene. When going back to the login scene, and trying to access movieclips like add eventlisterners etc... it comes back with null object reference, claiming that my buttons which are on the stage are null and sure enough if I debug they are. Any reason why my movieclips are being made null when moving between scenes?

I have a test main.swf with just a UI loader component loading in an external .swfThe swf is a flash scroll using the component class. The swf works fine on its own but when used with the UI loader I get an null reference msg.The files have xml, .as and css files in the zip.light on why I get this reference as the scroll and text appear in the main.swf but the scroll does not function.
View 3 RepliesI have a movieclip that I add to the stage and Im trying to reference a input text field on the second frame.When I trace the textfield on the first frame via the constructor it returns object textfield correctly.When I hit the enter button to go to the second frame where I will need to use password... I get a null when tracing. I can see it, I can write in it and no matter what I do I cannot seem to reference it.
Code:
public function Registration():void
{
trace(this.usernameField); //returns textfield correctly[code]...
In case you need the parent of registration its just the document class and I create registration like this..
Code:
var registration:Registration = new Registration();
addChild(registration); //ive also added it to the stage w/ no luck
Why does this code not work? It seems to make the error:#1009: Cannot access a property or method of a null object reference. my buttons on the same frame have all stopped working
