I can't make this code work in Flash CS4, it keeps saying that the listener parameter can't be null or that the index is invalid.
ActionScript Code:
addEventListener(Event.ENTER_FRAME,f_entraframe);
function f_entraframe(event:Event):void[code].....
this is the error I am having:
TypeError: Error #2007: Parameter listener must be non-null.at flash.events::EventDispatcher/removeEventListener()

here is my code:

View 2 RepliesCan't figure out why I'm getting this error:Error #2007: Parameter listener must be non-null. I have traced the xml, so I know the values are loading, so don't know why I"m getting a "non-null" error.The first value in the xml traces correctly, but then the error occurs.I only receive the error when I pass the popup argument to createImageHolders, and I don't know why...

We are getting ready to start trying to convert our older content to AS3.To this end, I have been trying to develop what I though would be a relatively simple. It just an attempt at an adaptable mc button class that my animators and designers can kind of "plug and play" so I can spread out some of the workload.I keep getting "Error 2007 Parameter listener must be non-null". I understand why its throwing an error. simplified block:
Package{
import flash.display.MovieClip
import flash.events.[code].......
The slideshow its referring to is a something I purchased online and is embedded into my movie.Does it mean I need to put and onComplete function on the page thats loading this? Is it for the xml or the slideshow movie?

I have had a go at using event listeners. So far I have failed. All I want to do is when I click my mouse on the bird mc it moves.Here is my code:

I do have some programing background from my past. anyways, on to the error listed in the title. I thought I was getting good with the Timer class, but alas, I think this error has something to do with my Timer embedded in my switch() code block:

I have a question about AS3. I'm new to coding/scripting/AS3/Flash, so I'm sure that I am making some rookie mistakes. I keep getting the following error (I only get the error when I use the if() conditional. If I remove it the code runs fine. But I need the functions to run only under certain conditions):

I am trying to trace the results of my listener when the browser is resized...no avail. Are you able to see what I am doing wrong?
I am having a weird problem with scope/reference. I am using a loop to preload a number of thumbs in one go, I am creating a different listener for each one on the fly and then passing event handlers for each one of them. This should not be difficult using a loop, but somehow I cannot access the the parent object on my listener and therefore I can't do much with my thumbs after they are loaded.Here is the relevant segment of my code. myThumb_mc is a temporary variable that does not exist when the loop finishes, you can copy and paste this code to test it though. It should work to that extent. (you'll need an image1.jpg to be in the same directory)
Code:
var myThumb_mc = _root.createEmptyMovieClip("myThumb_mc", _root.getNextHighestDepth());
myThumb_mc.clipLoader = new MovieClipLoader();
myThumb_mc.clipLoader.loadClip("image1.jpg",myThumb_mc);[code].....
The code above works, but it does not look nice and it cannot be the right way of doing this. Long question short, how can I access the parent of a listener from a listener object? ._parent does not work.
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.

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.
I have create a menu but when clicking on menu so that it shows, I get an error on the line because of the line "myMenu.show(null,null)". See function below:
private function createAndShowmyMenu():void {

myMenu.labelField="@label"[code]........
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"));
[Code]....
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 RepliesWhen 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 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.
This is something that tugs at my mind a lot so I figured I'd ask the community. If I have a class called MyParentWidget and it contains an instance of MyChildWidget with an instance name of myChildWidget then I will often do something like this:

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 RepliesQuick question, can an object get the same event listener applied more than once? For instance if I have myObj.addEventListener() and then later in my application I apply the same exact listener on the object again does the listener get applied on the object thus increasing memory consumption? or does it get re-written over?
View 4 RepliesI am trying to add a key listener. I'm pretty sure this was working recently, but now it isn't, and can't figure out what is preventing it... I am saving in Flash 6.

I tried to add a listener but nothing happens....I mean nothing happens.
keyListener.onKeyDown = function() {
if (Key.isDown(Key.TAB)) {
if(des.text != "FRED"){[code]...
We want to set focus in atext field then when the user presses the Tab key we want to see what's in the field and move on the timeline.When I put the code above into a new file it works fine but if I put it into my course file or even bring it in using a loadmovie it doesn't work anymore.If I use a simple on realease key = tab on a button it works in a new file, but not in my course file.
I am trying to get this simple event listener to work.

I want to add a key listener to my stage, but from an object 2 depths below the stage. How would I do this?
I thought about adding the listener from my doc class, but the listener function is in the object that is two depths below the stage, which would mean I would have to pass the key values to the next movie clip, then when that one is loaded, pass it to the one with the listener function. It seems very complicated, is there an easier way which keeps with the principle of OOP?
