ActionScript 3.0 :: #1009: Cannot Access A Property Or Method Of A Null Object Reference?
Aug 24, 2010
I know roughly what the error means. And used to solve them, but with this one i cant. So: On the frame 4 im creating 3 different dataGrids. There is some code in there and the button which will take you back to the frame 2. So i get this error every time i click the button to go back. + instead of seeing frame 2, i see frame 2 mixed up with frame1. I went through the code, and found out, that the error occures only because of one of the lines:
ActionScript Code:
addChild(dataGrid1);
addChild(dataGrid2);[code]....
Component dataGrid was added on the fourth frame, but then i added it to the first frame.All the imports are on the first frame.

I have this preloader code on frame 1 in my MAIN swf file with the content on frame 2
Actionscript Code:
stop(); //Import the required assetsimport flash.display.*;//Stop the playhead while loading occursthis.stop();//Create a listener to call the loading function as the movie loadsthis.loaderInfo.addEventListener (ProgressEvent.PROGRESS, PL_LOADING);/*This is the main function,
[code]....
Also an external swf file is loaded using the same code on frame 1 in its main timeline this works when I test local but it outputs an error....
at welcome_fla::MainTimeline/PL_LOADING()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at welcome_fla::MainTimeline/PL_LOADING()
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've googled this error a ton but haven't found anything relevant yet. I'm in an AS 3.0 class (as in a room with people and a teacher and text books and lectures .. not a class file) and we're all getting the same errors.Basically we all have to create a file with 10 buttons. Each button needs to go to a new frame. On that frame we have a separate actionscript 3.0 code that does something (for this question, I do not think it matters... each script on each frame has to show off a different AS 3.0 code that proves we've learned something).
So let's say we have 11 frames. Frame 1 has the navigation and the intro. Frames 2-11 each have a stop(); and a new code.So each frame has different content (except for the background and navigation buttons which are consistent on all frames). The problem is that on one frame we have an ENTER_FRAME on a movie clip that points to a specific function. On that particular frame it works fine but once you navigate to a new frame on the timeline - the function continues to run in the background and we get the "#1009: Cannot access a property or method of a null object reference" error. (I assume it's because on the new frame the content from the previous frame no longer exists. By content I mean the movie_clips/buttons/etc..)Once the functions start to run on top of each other in the background - the entire SWF just devolves and breaks down because it's trying to do too many things at once.removeListener seems like the obvious answer but on each new frame it generates an error because it can't see the content from the previous frame on which the Listener was added. Putting it on the navigation button codes doesn't seem to work either.

Thats the error messege i get when it tries to play. What I have is an swf that loads another when its done, the new swf is blank but has a document class to an AS file.It seems the problem lies when a function is not properly being added to the stage.The function is added like this..
Code:
package{
public class QuizApp extends Sprite{
public function QuizApp(){
createButtons();

I have a movie clip that starts lets say @ frame10 and ends @ frame20 I have a button to toggle the visibility of that movie clip on/off even if the movie clip is not currently displayed on the stage. The reason I am getting Error #1009: Cannot access a property or method of a null object reference is because my movie clip (as I read from previous posts) has not been instantiated yet.
I have over 50 movie clips like this one (to act as labels, as i scroll through the timeline the labels appear and disappear to follow an anatomical structure on series of images). Is there an easy way to instantiate all of those movie clips although they start and end at different points on the timeline? I got a headache from finding a solution for this.

This seems weird. My code worked in the original FLA (using AS3) but when I 'Save As' as a new doc,
It gives me a compiling error below:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at flash_fla::MainTimeline/frame1()
Does it have to do with path to the Library? Is there a way to reset this within Flash or do I have to copy and paste the code to a totally new AS3 file?

I am creating a little mini site for the web. The buttons within the movie work fine but when I create a button from a graphic, and try to tell this to link to an external website and open in a new window I am getting : Error #1009: Cannot access a property or method of a null object reference, in the Output and when I click on the button nothing happens. I have found lots on the web about this error but nothing that i can understand enough to fix the problem. I just want to make a button from a graphic and link to somewhere - the code I am using for the buttons is:
vim_btn.addEventListener(MouseEvent.CLICK, vim);function vim(event:MouseEvent){navigateToURL(new URLRequest("http://www.vimeo.com/"));}
I have this code attached to a key frame .....what does this error mean and why can't I do this seemingly simple thing?

I ve got a very simple combobox, 3 data items and an event handler. The catch is that the combobox is in an external swf loaded into the main swf through the loader class (worked fine in CS3 & CS4). Heres the only AS3 code for the box:
[code]...
The symptoms are as follows: When used in an external swf the combobox does not show index 0 (it blank) and when clicked throws the following error: TypeError: Error #1009: Cannot access a property or method of a null object reference.[code]....
When the external swf is run independently the box mostly functions, it does not throw an error and properly calls the event listener, however, it does not show the default selected index and when the combobox is changed it does not keep the current selection visible.This worked perfectly in CS4 & CS3, theres really nothing complicated about it. I have entirely deleted the old CS components and replaced them with brand new CS5 components,

I have TextField instance called inputWord which contains no text on the first frame. On the same frame, on the actions layer, any time when I refer to inputWord in any way, there is an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at DC/frame1()[DC::frame1:19] //DC is the name of document class that I created.at flash.display::MovieClip/gotoAndStop()
at DC()[C:Users
ikkkaDesktopflashDC.as:25]
19 is the number of line where my code that involves inputWord is located. It works, I mean I write
inputWord.text = "smth"
it text becomes "smth" but there is the same error. Why?
