i added a display object like so:
var backButton:BtnSMenu = new BtnSMenu();
backButton.name = "backButton";
mainHolder.parent.parent.parent.addChild(backButton);
but then later in the code i want to remove the child so i did this:
mainHolder.parent.parent.parent.removeChild(getChildByName("backButton"));
but i get this error:TypeError: Error #2007: Parameter child must be non-null.
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;
[code]....
With the code below I get error #2007: Parameter child must be a non null if I move
ActionScript Code:
var pictLdr:Loader = new Loader(); above B.addChild(pictLdr);
the problem goes away but the buttons react by jumping to left side of the screen. No image loads and there are not errors.
ActionScript Code:
var buttonArrayportfolio:Array = [ B1, B2, B3, B4, B5, B6, B7, B8];
for each( var B:MovieClip in buttonArrayportfolio)

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:
trace("REMOVE: " + propGFX);
removeChild(propGFX);
Here is what the function traces and the error it gives:
REMOVE: null
TypeError: Error #2007: Parameter child must be non-null.
HOWEVER.... If I comment out the "removeChild(propGFX)", this is what it traces:
REMOVE: [object grasstreeTile00]
Why would propGFX be null if that line is in the function right after it? This makes no sense to me at all.
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 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 am building a quiz using XML for the questions and a ButtonTopLevel class to control the behaviour of the buttons tasked with choosing a question. Basically, the docClass imports the XML, makes sure it is fully loaded and then adds these top level buttons as children. I need to maintain the MouseEvent.CLICK in the button class because once the button has been used, it will switch to feedback mode and no longer be available as a button. Once clicked, the button says:
[Code]....
I have a sort of "go back" button in during development, and if I go back to the top level buttons and click any one of them, it works as it should. There is nothing undefined, with the possible exception of a variable or two I've declared and not yet used. Is it something in the way I'm telling the child to talk to its parent? My code is rather lengthy, but I will post if need be - just hoping it might be something I'm missing in this call to the parent.
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
textFlow="{TextConverter.importToFlow(rdesc, TextConverter.TEXT_FIELD_HTML_FORMAT)}"
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

View 2 RepliesI'm trying to build my portfolio navigation and its giving this error:

The problem starts when I click on the buttons.. I want to change the page with my targetMC; But it's not working.. What's the matter?
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"));

I have an Movie Clip in Flash that have subobject of button type which has subobject of input text and movie clips. Right after creation core Moveclip all subobject are set to null, when I expect them to be valid objects.

MC_Core_design was created in Flash and exported to Actionscript. I've done this for button_1 class aswell. The code was written using Flex. When I comment out both lines that result in error I get correct view of the core Movie clip with all subobject. How can I set subobject properties right after object creation?
a quick low down would be its a gallery on the second frame and I breaks when coming back tot he first frame, all tweens die and such.

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 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]
