I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
View 4 Repliesthe 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.
I added a flv into my Scene 1 then i added a new Scene.I just wanted to after finishing the .flv flash go to next scene.but when i added a new scene,and I test my movie,the .flv didnt show and i recieved these errors

This is my code,
stop();
button3.addEventListener(MouseEvent.CLICK, playClick3);
function playClick3(Event:MouseEvent):void {
gotoAndStop(422);
}
On frame 422 there is no code at the moment. I keep getting the error TypeError: Error #1009: Cannot access a property or method of a null object reference.
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?
View 4 RepliesI am trying to use the scroll pane component and I am having a few teething troubles. I have a scroll pane as a child object of a movie clip which is essentially a 'page', if I display this page it works fine and the scroll pane does too. If I then remove this page from the display list, go to another page and come back by readding it to the display list, I get the following error, even though nothing else has changed:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at fl.containers::ScrollPane/fl.containers:ScrollPane::endDrag()
The scroll pane is still visible and works correctly, but ideally I'd like to stop this error.
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.
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)

I'm having a problem with this code for selecting a character for a game. The scrolling left and right codes work but when it comes to accepting the highlighted character.[code]All I want is for it to take the label of the current frame in the movie clip (which I defined already) and set it to a string, selectedChar.[code] p1c is an instance of the movieClip containing the characters.
View 2 RepliesI am trying to figure out the logic to remove a nullreference error that is popping up when an item is not dragged. Inthe code, I have a stopDrag setup for the stage. It works asexpected unless the user clicks the item but doesn't drag it. Itcauses the variable I have set to bring the name of the dropTargetto be a null which crashes the system. I have tried to declare thevariable with a default value but it still doesn't work.It is the targetStop code that it is crashing on. Is thereanyway to default a value so I can do an if / then statement todetermine if there is a value? I've tried: if (targetStop == null)but that doesn't seem to work.
View 8 Repliesi'm using a Rails backend with my App and getting a AsyncToken returned from it (a DB-Call to be specific)As far as i know the AsyncToken returns a result event when done loading all data from the request, this way its possible to make sure all data was loaded before executing some function which uses the data. i tried the following implementation to get the AsyncToken converted into an Array and plotting its objects as strings to the user:
var dataSrv:services.databaseservice.DatabaseService = new services.databaseservice.DatabaseService;
dataSrv.addEventListener(ResultEvent.RESULT, dbListener);
//DBOPERATION returns my AsyncToken
var listData:AsyncToken = dataSrv.DBOPERATION;
But i keep getting a "null object-pointer" error!

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();
[Code]....
Here are my classes
Main - creates preloader
Preloader - createas Website
Website - creates MainMenu
When a button in the main menu is clicked, it creates an object. And when another one is clicked, that object needs to be removed. The removing part got a little bit messy.
package src {
import com.greensock.TweenLite;
import flash.display.MovieClip;

i used some variable, which was not initialized properly. I got a runtime error related to Null Object Reference.It was a hell, to find out, which variable was it pointing to. Cannot it be more informative, if it says, on which particular variable ( or bunch of variables), did the compiler found the null object reference. Or atleast provide me the lineNumber/linenumbers where it find the null object.The informationlessness becomes more hell, when there is more than one line, in which such null objects are used. It's hard to determine, if the line removed currently was a correct attempt or wrong attempt towords debugging the code.

When I try to run this code with the main file being documentclass and the highest in the code heirarchy, it comes up with error 1009, but I cant see the problem. The playscreen class with the constructer function is there, in the same folder as the document class but document class is saying it is a null object reference. When I try to run the code with the main file being playscreen, there is no problem, it runs perfectly.
[Code]...
The playscreen class is too big to fit here and I dont want to trouble you with the details. But I can assure you it DOES exist and it is NOT null.
I've been fighting with this backwards and forwards and haven't identified the problem:I have three frames that I want the user to page through with forward/backward buttons. Three frames means 4 buttons, two forward buttons and two back buttons:[code]What it does is, the lets m press the first Next button and does go to the second frame, but it throws the following error and the other buttons don't work:[code]Why can't I shake this thing? Is there a better way altogether?
View 3 RepliesI have an error that is not negatively effecting anything, but I'd rather fix it if I can. I have to do with "MouseEvents" when I change from one scene to the next. As in the objects do not exist in the "new" scene so there is a "null object referenced" error. The objects are not referenced in the new scene. Its a "mouseOver" and so when the scene changes and the "MouseOut" happens it tries to exicute a funciton on an object that is no longer available. I was thinking of changing the functions to "if/Else" statements, as in:
"if currentScene=X Mouse out, Else "NOTHING"
I got CS4 for Cristmas, and I am having trouble with my buttons. I have a button on each frame programmed to go to the next frame when I click it.

This might be alittle complicated to explain but I'll try to do my best.I have a basic setup of 3x4 isometric boxes that you can drag and sort around on a grid. This works just fine. Each box is a instance of a custom class of mine called Kiste (which consists of several sub-objects).hile sorting I have to use a procedure like this to get the parent Kiste-object of the dropTarget as droptarget will always get me the "lowest" object possible instead of the topmost:
Code:
function whileDrag(e:Event):void{
var dt:DisplayObject = dropper.dropTarget; // Dropper is a empty Sprite that is constantly

Basically I have 2 classes, A and B. B derives from A. Inside A, I declare a static variable/constant to the class of B. When I run the program, I get a null object reference error, with the line pointing to the class declaration of B, i.e.
Code:
public class B extends A
For reference, these are the 2 classes:
Code:
package
{
public class A
{
[code]...
Also, this error only occurs when the variable is static. If it's just a normal variable it works fine, i.e.
Code:
private var OTHER:Class = B;
If I change the static variable to point to a different class, it's also fine, i.e.
Code:
private static var OTHER:Class = Main;
I can probably work around this, but it's a bit of a pain in the ass. Anybody know what's causing it, or is this a Flash bug?

On line this prevents it from working at all.Basically I need each external content to have its own preloader for its content.If you go to my site you will see it works on the intital load but when you hit the home button it fails [URL]
I'm having a hard time because of an "Error #1009:Cannot access a property or method of a null object reference" Iget everytime I try to run my Flash-movie. I've attached the codethat is contained in frame 1.The function bringUpEasyQuestion is defined on frame 2, alongwith other functions that are defined there. Now when I test themovie, I get this message:TypeError: Error #1009: Cannot access a property or method ofa null object reference.at MES_fla::MainTimeline/bringUpEasyQuestion()atMES_fla::MainTimeline/frame1()I've read that the Error1009-message means that you aretrying to access something that isn't there yet. And indeed, thebringUpEasyQuestion-function accesses objects that exist only onframe 2. But the first line of the function bringUpEasyQuestion isgotoAndStop(2);. The curious thing is that it works when i put thelast line of the code in frame one (the function callbringUpEasyQuestion(0);) on the first line
with the command gotoAndStop(2);?
