I'm getting this error: Error #2025: The supplied DisplayObject must be a child of the caller
I've read about it here and on other forums, but have not come across the same situation I am in, I fixed it but am just looking for clarity:I create 3 containers, one for a slideshow that gets masked by graphics, another that contains the navigation, and a 3rd that contains the content the navigation will load. I create the slideshow container and it's mask, then I create the nav container, then later I create the content container. I want to removeChild(contentContainer) after I choose a second navigation item or just want to clear the content. Simple, and it works fine, done it a million times.
THEN: I want the contentContainer to have an index number between the slideshow and the navigation containers. I set the slideshow container index to 0, then the content container index to 1, (and I've tried a number of other combinations) and I am no longer able to remove content container beacuse of the error that gets thrown above. In fact any combination of setting the content container to anything other then 0 will throw this error. Why would this be? The only answer was to set the content container index to 0, then set the slideshow index to 0
works:
setChildIndex(contentContainer,0);
setChildIndex(slideshowContainer,0);
function mouseUP(e.Event){ removeChild(contentContainer)[code]....
I keep getting them, and can't figure out where or why I'm getting them.Here's the full error reports:

I always have the trouble that make different classes communicate with each other.
1. using get set methods
2. eventdispatch to dispatch custom event.
Today, I am working on this confused issue again. I still can't get through it.this time what I wanna do is this: I wanna use a button (_zoom) to control a mc (_board) located in different class. Let's me give a simple structure for you:
ProjectAppear.as
|_ _board (mc)
|_ Project.as
|_ _work (mc)
|_ _zoom (mc)
My thought is I add a mouse event listener for _zoom, and then when mouse click it will dispatch a custom event..
Im building my first OOP project with classes in AS3, Ive done a lot of tutorials and Im grasping the concepts well. Im just having trouble with the concept of communicating between classes. Whats the best way for a class to talk back to its parent once its instantiated? It seems when your inside a class, you're kinda stuck there as far as scope goes? ie one way street. Or am i missing something? Im used to the days where I was coding on the timeline and could just use this._parent etc. But obviously those days are gone.Or should I not need worry about this If I have planned the structure/heirachy correctly?
View 14 RepliesI had a question on OOP and the best practice for how to communicate between classes. If I have a class (SiblingA) where some one clicks something in it and you need to interact with another Class (SiblingB), what is the best method for doing this?
(option1) Should I have a bunch of event listeners in the Document Class that respond to these events? (I thought you wanted a document class to be as small as possible). (option2) Or should I create a separate 'Utility' class that speaks with both siblings to facilitate communication (event handling) between the two (one class with many public static methods). I have attached a diagram to try and help explain this.
Often times these events are dispatched from children of children in sibling classes (ie childOfSiblingA or even its children) Option1 Scenario: A user does something in SiblingA, that dispatches an event to the doc class which listens for it, fires its listener function which calls a (public) method in SiblingB to handle the interaction.
Option2 Scenario: A user does something in SiblingA which calls a (public static) function in Utility class which calls a (public) function in SiblingB to handle the interaction.
I think I am leaning towards option 1 but that would be a lot of dispatching events (child dispatches to parent, dispatches to its parent, dispatches to doc, doc calls child, which calls its child, which... finally does something)
I need to know how to reference variables in other classes. I have been avoiding this by referencing variables from the Main class, where they are created. But at this point I would like to be able to have the option and it would make me a better programmer.
Say I create a movieclip in the Main.as
Code:
public var Enemy_mc:Enemy = new Enemy();
addChild(Enemy_mc);
[Code].....
How do I do that^ without creating a variable in Main.as and having it check Background.as for variable updates?
Can I do something like "Main.Enemy_mc += 5;" like I can do in Main.as to variables that I have created in Main in other classes?
I don't know how to phrase this, but as you can see my code below I have 2 classes.
1. wp_title
2. wp_date
How can I let wp_date to get the height of wp_title's contentText? Currently I tried tracing wp_title.height from wp_date but all I get was 0, I guess it doesn't get the height after wp_title finish loaded. Currently the classes will perform an action after I resize the stage. I assume if I'm able to get the classes to communicate with each other than I could have 1 main classes to control the actions perform in other class?

package {
import flash.display.Sprite;

I know there are forums posts across the web with answers to this question, but I have yet to solve my issue with any of them. I've been looking for over a week trying to figure out what's wrong with my swf file.
I have the parent (europe.swf) loading swf files on Mouse Click which loads the loader and adds the child... (netherlands.swf). That all works fine, then there is a button within netherlands.swf that has a dispatchEvent, which the parent swf receives fine, I've checked with a trace. But then when I tell the function of that dispatchEvent to removeChild I get this.[code]...
a function generating the game buttons

I've got a problem in an ItemRenderer in Flex 3.5. I've looked at the other posts regarding this error but still can't figure it out. The ItemRenderer is part of an AdvancedDataGrid who's data provider is HierarchicalData. I'm getting the ArgumentError but the trace doesn't go to any of my code. I've gone through in debug mode tons of times but it looks like it doesn't happen until after my code runs. Quite strange.
The item renderer has a couple different parts. It figures out what row it should be drawing for based on the xml data and then adds labels and sprites appropriately.
Here is one of the methods that gets called if the itemrenderer is on a certain row.
private function addLabels(planList:ArrayCollection):void {
height = 0;
var sprite:Sprite = new Sprite();
var curX:Number = (width / planList.length);

I am encountering a problem with removeChild with MouseEvent that drives me nuts since two weeks. I would like to add a child ("d_li.swf" which is a slide) when one button "li_120" is pushed and remove the same child when other buttons like "values_121" and "profile_301" are pushed.

I have to arrays, they both hit detect against each other. When they detect a hit they each launch a method in the custom class as well as splice the entries out of the arrays. Now, I CAN NOT remove the child right their cause that causes them to immediately delete themselves from the stage, I need the death animation to play. I can't remove them in the class cause it says it can only be removed from the caller.
Code:
for(var b=0; b<blastArray.length;b++){
for(var s=0; s<boxArray.length;s++){
if(blastArray[b].hitTestObject(boxArray[s])){ //test if they hit each other
[code]....
If I put removeChild(this) in the boxArray method .die, I get a 2025 error.
If I try parent.removeChild(this), I get, cannot access property of a null object. 1009 error.
I have a UILoader (called alleyLoader at the moment) on the stage that loads and scales an image. I want the user to be able to click on that image and have a pop up of the full scale image. Then, when they click on the full scale image, it disappears. I chose UILoaders because there will be quite a few images on scattered throughout the site and I don't want to have to call them all through code. Also, I figured it'd be easier to scale them. Most of the code is working, but I'm noticing a few odd things. [code]...
View 4 Repliesi try to program a little shooter game and right now i would like to implement a piece of code, which causes an enemy, as soon as it was killed, to explode. This explosion should then kill and remove all remaining enemies on the screen.
This code is embedded in a while loop, which checks bullets vs enemy collisions, which is on its part embedded in a timer function.
Of course i was looking this error up and it seems, as if i was trying to remove the displayobject enemy although it no longer exists, but unfortunately i can't really figure out what i did wrong.
I bolded the removeChild command which causes the error.
Code:
var avatarHasBeenHit:Boolean = false;
var enemyHasBeenHit:Boolean;var i:int = army.length - 1;
while ((i > -1))

I have a portfolio page on my website (currently in-process) where I display flash samples. To avoid antiquated and uncontrollable pop-ups and js code etc that could be disabled, I went for a very clean/controlled approach by using flash's fullscreen capability. To achieve this, I am using indivdual swfs as thumbnails. Each thumbnail swf listens for a click. Once clicked it fires off its fullscreen mode, loads an external swf file, and positions my assets (the swf file and a custom exit button) perfectly on the screen according to your specific resolution settings. Everything unloads and goes back to normal via a fullscreen event listener, so it doesn't matter how you exit fullscreen mode (via button or escape or whatever). Everything works great in all browsers I've tested, except.In browsers other than Explorer I get the following error when returning to normal mode. Everything works fine, but the error window pops up.[code]

I have a swf file that is loaded via addChild on frame 11, once the animation of this swf file has finished playing, the main swf then goes back to frame 1. However, this is where this issue comes in. Even though I have removed the child once, it seems to keep on trying to remove it again and again, this goes in to a continuous loop.

I have a display() function for an object rotator(image based like a QT object movie). It first saves the current image in a helper variable and then allocates a new image, from the library, beneath the old one. To get a nice crossfade effect, the old image's alpha is looped down via enter_frame and then removed.
Which is where there seems to be an issue with the display list, maybe recognizing oldImg's value as being already added? (it's not a first pass error)
Btw, do i have to remove the old image or can i leave it, for when it's being called up via the mouse position again? (the image number can get fairly large)
function display(num:Number):void //num: image number
{
...
oldImg = newImg;

I have inherited a FLEX 4 project that invokes web services to display data to the end user.
My default package has one .MXML file, that has the component references to the Login screen (another .MXML file) and the Main screen (yes, another .MXML file).
The login process works fine. I have 3 tabs, with a 4th tab I am adding now.
The tabs are created using elements within a TabNavigator. I have added a 4th VBOX, like so:
<mx:VBox label="Data Analysis" width="100%" height="100%">
<componenets:DeviceLineChart />
</mx:VBox>
