Can'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... I"m a 3.0 newb.

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:

And here is the TypeError:TypeError: Error #2007: Parameter listener must be non-null.at flash.events::EventDispatcher/addEventListener()

View 1 RepliesI'm trying to program a race timer with OOP, and I've been adding more and morefunctionality to its class. Everything had been running well, until I had the idea to put a countdown() function, to make a cool countdown effect. Things got worse when I wanted to make the countdown function to call another function when the countdown effect has finished.The code runs well when I first pass a function parameter from the Main class to the Timer'scountdown() function. The problem begins when I want that function to be past again on other private function of the same class, because this time, the function becomes nullOn the Main class constructor, I 've written the following line:
ActionScript Code:
timer.countdown(5, false, myFunc);

I am building a shoppin cart in flash and I am having a problem getting the purchase items list to work. Each item which gets added to the cart gets put into a movie clip and added into a purchased items moveClip which is on the stage. Each child item has a remove button attached to it. So if the user wants to remove the item they can. The problem is when I remove some of the items on the list I get a "Error: Parameter child must be non-null." Here is the code aswell:
//The cart_array is where I want to store incoming items in.
var cart_array:Array = new Array();
//The items_array is where I want to store the "purchased_mc" MovieClips inside once they have been put on the stage.
var items_array:Array;[code]...........

I'm having this error in which I have a Main Menu scene, an Options scene, and a game scene. I have a external file which holds all the public variables that I need between scenes. In the game, there is a picture of water in the background which is purely decorative and doesn't do anything, the only time I use it in code is when I'm moving it to the back so other platforms can be positioned on top of it by using the code:[code]This used to work before I put the options scene in, and still does, provided I don't go to the options scene. Even if I don't touch anything on the options scene, simply going there causes this line to throw a "Parameter Child must be non-null" error. I tried to trace gfxWater right beforehand, but just got null. I simply dragged the water onto the screen to create it and gave it the instance name gfxWater. I don't understand how that could be null, its still there even when this line breaks, it's just on top of everything else.
In the options menu I am not doing anything with the water, I'm only changing variables such as whether or not to play music or sound effects, stuff like that. Nothing relative to the water. The only thing that I can think of that might be causing a problem is that I used a custom font in the options scene, so I had to create the text in AS3.[code]
I am trying to lay some items out on the stage using a timerEvent, out side of the "timerHandler" function the items lay out just fine. My question is...why am i getting this error when running the timer and the function. The code is below...

dragDropItemNum = xmlData.dd_setup.dragItems.dragItem.length();

I am getting this error, whenever i loaded an external SWF file. I had an Interface, in which a glossary icon is set. So, when clicked, the glossary swf file has to be loaded in to Interface. So, I made a loader and added to display hierarchy, but left empty. So, when glossary icon is clicked, i am loading this specific glossary SWF file in to that loader. But, as it is added, the following Error is thrown.

I'm new to ActionScript and have a fairly basic question. I want an eventlistener to call a function and pass it a parameter that will send the movie to a specific frame. My code generates and invalid parameter type error. It's as follows:
TL_AboutUs_btn.addEventListener(MouseEvent.MOUSE_OVER, DropSubMenu(10)); // calls a function to drop a sub menu
function DropSubMenu(sm:number)
{ gotoAndPlay(sm);}
Error is "1046: Type was not found or was not a compile-time constant: number."
I'm working on a sliding gallery like Hulu. Setting it up and the sliding slides in and out is working fine. However, I need to add and then remove a button to each slide as it comes in and goes out. (I initially tried including the button on each slide, a mc, but this proved problematic for the event listeners). So when the file loads up, I add a mc to the first slide of the group like so (features[] is an array of movie clips - my slides):
Code:
var goBtn:MovieClip = new FeatureButton();
features[0].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
So I add the button/mc to the first slide - works just fine.
So there are two handlers, next and previous. So I started with the next handler. The first thing I have to do is kill the button on the panel that is sliding out, so I do that like so:
Code:
features[featureCount].removeChild(goBtn);
goBtn = null;
(featureCount is a counter keeping track of the slides). This works fine. I click the next button, and the button on the slide disappears and we move to the next slide - perfect.
So then I add the following next - exactly like I did in the beginning:
Code:
var goBtn:MovieClip = new FeatureButton();
features[featureCount].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
This time adding it to the current slide coming in - but this generates the following error:
Code:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/removeChild()
at featuregallery_fla::MainTimeline/nextFeature()
How I'm getting an error on the removeChild() when that is already gone. I assume "parameter child" means goBtn - yes it is null because it's been removed. But I'm not trying to do something with that. I can only guess this is a variable scoping issue with goBtn - but I'm not seeing how to resolve it. Flash file attached.
This error comes up every single time I try to run a simple AS3 tutorial flash file on my website..Things I did:-server php support check was run. (success!)-using html to call php for a simple registration form.(success!)-ANY flash file to do a two way communication with a php file ( FAILS!)I tried maybe 10 different swf files and php files that go with them.

I'll try to be as thorough as possible so there isn't any question as to what is going on or what it is I'm trying to acheive. I've been asked to build a digital catalog for my company's products in Flash.The program is simply an organized way to view files that will be contained with in the same folder as the swf file. The program consists of one scene with five buttons that control the timeline, and each different part of the timeline has a movieclip containing the buttons that open the different files. There are only two of these types of buttons: one is bu_video and the other is bu_brochure. They both have several button instances differentiating between different products. For example: Product A has two buttons: bu_video (instance name videoA) and bu_brochure (instance name brochureA). Here is the code I'm using to get the desired effect.
mc_cutButtons.addEventListener(MouseEvent.MOUSE_DOWN, action, false, 0, true);mc_cutButtons.addEventListener(MouseEvent.MOUSE_OVER, action, false, 0, true);mc_cutButtons.addEventListener(MouseEvent.MOUSE_OUT, action, false, 0,
