ActionScript 3.0 :: Error : Parameter Child Must Be Non-null?
May 11, 2009
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 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...
ActionScript Code: // dragDropItemNum = xmlData.dd_setup.dragItems.dragItem.length(); var tmr:Timer = new Timer(1000,dragDropItemNum);
i have the following script , and its giving me this error...this occured after i wrote the last line... which will unload the about section if home is pressed...
var imageRequest:URLRequest = new URLRequest("home.swf");var imageLoader:Loader = new Loader();imageLoader.load(imageRequest);addChild(imageLoader); imageLoader.x = 0;imageLoader.y = 140;
having some probs with this bit of script, all works fine until i try to remove the mc from the stage and I get this:- TypeError: Error #2007: Parameter child must be non-null. at
[Code]...
have tried lots of things but still get the error or others.
I have used the online document [URL]to create a dataGrid that fills with an XML document. All is good there when I run my swf all works as it should. BUT... when I run my course that adds this swf file as a child I get an error reading in the data....

I'm having problems referencing a child i created.I've got a movie clip in my library called 'image'.a container movie clip called 'picTweens' on my stage (its instance name is the same)and in the actions panel in the stage i've got a function which contains
ActionScript Code: var pic:image = new image(); pic.smoothing = true; picTweens.addChild(pic);
all well and good, it creates me a movie clip where it's supposed to.now in an if statement in the same function, i have
ActionScript Code: picTweens.removeChild(pic);
but when that if statement triggers,(and i've got my pic loaded where it's supposed to be)it tells me :
Code:TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/removeChild().is my syntax wrong? and if not, then what should i check for?
This code is within a class called "Tile", which has a public variable (MovieClip) set named "propGFX". I am trying to call the function removeProp, which will remove the propGFX movieclip. These are the only 2 lines in that function:
i'm just trying to deduct the life of the main character when it comes in contact with the enemy but it gives me error "Parameter child must be non-null. I placed this function in enter frame because i need it contantly check. and when the main character comes in contact with the enemy, it deletes everything in life_arr.
enemyarray length is 6. function hitEnemy():void[code].....
I just started working with Flash and I am quite lost with this error. When I bring up the swf file, it seems to be working semi-proper, but I am unsure why this error is coming up. I am basically trying to make a simple drop down menu. Here is the script if anyone can look it over and find a problem. (this script is on the main page)
I have a class that creates a navBar with some buttons. Each button loads an external .swf and everything is working just fine BUT the code is really awkward. I also wanted to use TweenLite to add transitions from section to section.I also wanted to handle the "section change" process from yet another Class (SectionChange) but whenever I try it I fail miserably. Here's what I have (including the vars), without the SectionChange Class, that's working.
private var _app:Sprite; private var _navData:Array; private var _loader:LoadDisplayObject;[code]....
I don't know what I'm doing wrong here but I get tons of errors with this code.
edit: Now that I'm adding the _sectionChange to the display list I only get the following error: TypeError: Error #2007: Parameter child must be non-null.
I can't get the maxDisplayedLines to truncate the text at the end of my RichText object. It comes up with Error #2007 Paramater child must be non-null but I don't have a clue what would be null. The text I'm displaying is coming from textflow
and everything displays fine, even the thumbnails until I try to set the max lines. This is for mobile by the way.
the error is TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/addChild() at flashx.textLayout.factory::TextFlowTextLineFactory/callbackWithTextLines()[C:Vellumranchesv22.0devoutputopenSource extLayoutsrcflashx extLayoutfactoryTextFlowTextLineFactory.as:267]
I have One SWF loading Two External SWFs seprately that have dataGrid components in them. The Externals load and run fine on their own but when I try to load them into CORE SWF I get ....

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 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 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.

The animation imports fine, but I am getting that error without the progress bar being shown.

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.
