ActionScript 3.0 :: Not Listening - Error "can't Access A Property Of A Null"
Nov 17, 2009
Take a BIG user submited image: say 2848x2136 pixels (I said it was big) and resize it with a Matrix:
[Code]....
And then add the bitmap to the stage on the next line.... throws the error "can't access a property of a null... blah blah blah" I get it, it's taking a while for flash to resize my gigantamus image, that's fine and understandable. Finally to my question: How do I set up a listener (or something else) to make sure the image is actually resized. I tried firing a method inside my resizer right before the bmp is returned, but that didn't seem to work. Only thing that works is a manual timer to slow things down a bit and that's just messy. I guess I'm wishing for a bm.draw(bmd).addEventListener(GRAPHICSEVENT.comple te, doneResizing); or something crazy like that. But I can find no such event in the package. Other ideas for making sure flash is done with bitmap data before adding it to the display list?

Starting new thread for this topic as suggested by forum. I have a website which tweens movieclip pages (named home, bio, music, video and contact). Love the effect and trying to keep it. Main timeline contains the main buttons (home_btn, bio_btn, music btn, video_btn, contact_btn). Music page has a XML mp3 player contained in it with button control. Video page has an encoded video with no code.
I need the following:
1 - Music and video to shut off as those pages/movieclips tween off the stage. Gets annoying with them playing especially at the same time
2 - Music player to play correctly. It is not with the new code.
I have the following code. The "Tween Code" is on frame 1 of the main timeline of the movie. The "MP3 code" is on frame 1 of the music movie clip. I am getting the following ERROR message when running my movie. I ran the Debugger as I publish and it points to music.my_channel.stop(); in below code. My thought process on this was that it would reach out to the music movieclip, find my_channel and stop it.

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.

I 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 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. All of the buttons worked fine until I put a movie clip on frame 12. Now when I click to get to frame 13, it goes back to frame 7. This is what it says in the output:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

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]

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..

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.

I honestly don't know what the problem is however, I think it has something to do with the preloader but I am not sure. I have posted the error and the codes used just for the home page but it happens on everyone.

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,
