ActionScript 3.0 :: Null Object Not Null
Sep 5, 2009
I am trying to add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.

the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
'null' is null or not an object
try { document.getElementById("").SetReturnValue(__flash__toXML(function() { return document.location.hostname; }()) ); } catch (e) { document.getElementById("").SetReturnValue("<undefined/>"); }
but this is from flash script and i dont have control over it. it just say JScript - script block.

When you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.

If I set an Object = null, does that remove all references to the Object's variables assuming there are no external references to said variables? Or do I have to manually set all said variables = null?

I have begun on a list: My reference is null!Stage is null! Convert this code from as 2 to as 3 for me! Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances. Mod note: I do not want this topic pinned, we will use a fresh topic once we have agreed to the content.

sometimes I remove child and trace it afterwards and it outputs null although I havent yet set it to null, why is that? and do I need to set it to null also in that case?
Code:
trace(holderArr[loadedThumbs].getChildByName("photo_bg"));
//[object MovieClip]
holderArr[loadedThumbs].removeChild(holderArr[loadedThumbs].getChildByName("photo_bg"));

I have an object which is assigned a number of properties:
var project_array:Array = [];
var slideObject:Object = {
project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?

I am getting this error, randomly when I start my application (and it's sub applications). As you can see the stack trace is rather useless, although through the debugger I can see the parent of container (second in the stack) is an MXML class that has a repeater that repeats another component. Therefore I guess the component with the problem is that repeated component, although I am unsure what I can change to stop this from happening. If anyone can give me some insight to the FocusManager or the getFocus() function it would be really handy.[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?

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()"
(tube_glow2_animate() being the name of a function)

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?
