TypeError: Error #2022: Class DS0$ must inherit from DisplayObject to link to a symbol

Hello,
When I tried AIR 3.7.0.1410 (ASC 2.0) to make an instance of a class that has AS linkage compiled as swc by Flash Pro, it fails on
TypeError: Error #2022: Class DS0$ must inherit from DisplayObject to link to a symbol
at flash.display::Sprite/constructChildren()
    at flash.display::Sprite()
    at flash.display::MovieClip()
    at flash.display::Sprite/constructChildren()
    at flash.display::Sprite()
    at (AS-linkaged class name)
while it's OK with AIR 3.6.0.6090.
I'm on Windows 7 and Flash Builder 4.7. Does anyone see this issue?
As for bug I put it here (Bug 3520793)
https://bugbase.adobe.com/index.cfm?event=bug&id=3520793

Hi Colin,
Can you show me how you're embedding the asset in ASC 2.0?
In Flash Pro, I imported a wav file into my library, configured the sound's linkage properties to export the asset, using the class name "ding". I then published the project as a .swc.
In Flash Builder 4.7 Beta 1 (updated to ASC 2.0 Preview 3, though I don't think this is necessary for this particular test case), I created a new ActionScript Project, added the swc to my project library path, and then instantiated an instance of ding and played it. It seemed to work fine:
package
    import flash.display.Sprite;
    import flash.media.Sound;
    public class SoundTest extends Sprite
        public function SoundTest()
            var s:Sound = new ding();
            s.play(0, 10);

AIR 3.7 Beta: TypeError: Error #2022 occurs for an unrelated class

On AIR SDK 3.7.0.1240, the error "TypeError: Error #2022: Class (flash.text.Font-derived class) must inherit from DisplayObject to link to a symbol" occurs when instantiating an unrelated class when launched in the Flash Builder debugger.
Include an swc with a linkage built with Flash Pro and instantiate a class (ClassA) in the swc results in:
TypeError: Error #2022: ClassB must inherit from DisplayObject to link to a symbol.

Does anyone see this? Because of this problem, I can't evaluate AIR 3.7 Beta at all.

Hello,
I am new to actionscript 3.0, I have Adobe Flash Builder 4.7 installed and I am creating a ActionScript project (File -> New -> ActionScript Project) named as Test. As you know flash builder does not include fl.controls package by default. I have added this package to my project as source path or swc file so that I can use the default components (e.g. Buttons, RadioButtons, Checkboxes) and now I am writing the following code.
package
          import flash.display.Sprite;
          import fl.controls.Button;
          [SWF(width = "640", height = "480", frameRate = "60", backgroundColor = "#FFFFFF")]
          public class Test extends Sprite
                         private var btn:Button;
       public function Test()
                              btn = new Button();
                              btn.label = "CLICK ME!";
                              btn.x = 100;
                              btn.y = 100;
               addChild(btn);
I am creating a fl.controls.Button instance in Test class and trying to add it on stage. When I run the project, it always gives me the following error for the bold red line.
TypeError: Error #2007: Parameter child must be non-null.

I know you are talking about Flash Builder but the same has to be true of Flash Builder as far as having the objects that go with the classes, especially if they are the objects that Flash Pro utilizes.
I do not use Flash Builder so I can't answer from experience how you go about getting the components into the library. What I normally do to find answers to desgn issues is to start looking thru Google.
If I search Google using the terms "Flash Builder use AS3 components" I get several results that might provide a solution. Here's one...
http://stackoverflow.com/questions/5602962/getting-flash-ui-components-into-builder
See if the answer for that one works for you, and if not, try some of the others in that search's results.

This error means that you are trying to set the text field but there is no data in the variable. As a first step, try to identify where this is happening, eg Is it the first call, or once you have submitted your data or only if you try to submit data second time?
Trace out the data that is returned for both completeHandlers to see if there is a missing var. Try this for "load_numbers" and "store_choice". Do it twice for "store_choice". Do you get back what you expected?
You could also try altering the php to return some fixed dummy variables, eg choice1Count=11&choice2Count=22&choice3Count=33, etc. If this works then you know that the error is in the PHP.
It looks to me like the issue is when you submit the data a second time and just get back the return_msg - the handler then tries to assign the choice1Count etc but doesn't have any count data back from the poll.php.
Test that there is data before assigning it, eg
 if(event.target.data.choice1Count){
 count1_txt.text = event.target.data.choice1Count;
 count2_txt.text = event.target.data.choice2Count;
 count3_txt.text = event.target.data.choice3Count;

UIComponent+Button=TypeError: Error #2007: Parameter child must be non-null.

I have created a super-simple Flash Component, -just a Button and TextArea together. These are both placed in 'assets' layer frame 2, with avatar in Frame 1, etc, and tied this to an ActionScript3 class, TestComponent.
When I use this component, in say, Tester.fla, I get the following error,
TestComponent1 Constructor called
TypeError: Error #2007: Parameter child must be non-null.
    at flash.display::DisplayObjectContainer/addChildAt()
    at fl.controls::BaseButton/drawBackground()
    at fl.controls::LabelButton/draw()
    at fl.controls::Button/draw()
    at fl.core::UIComponent/callLaterDispatcher()
If I include the 'Button' in Tester.fla library, the error goes away. But I don't have to do this for the TestArea.
It appears that 'Button' need special treatment in Flash. I have seen this question asked several times before in different ways, and never answered.
I would appreciate some explanation for this strange behavior, or if I designed my TestComponent incorrectly, then please advise on the correct design.
Thanks
Andrew

Hi,
I am not able to find sharepoint word in your post so can you please confirm that your question is related to sharepoint?
> Class not registered
For you issue, this error usually comes if you don't have DLL in proper place so add SWFToImage.dll in GAC and then add this assembly reference in your project from GAC.

TypeError: Error #2007: Parameter text must be non-null

I am new to AS period, but I am following some training videos for AS 3.0 to create a portfolio site where the images and text are loaded by xml.
I have followed the instructions to the letter; however I am getting the #2007 Parameter text must be not-null error.
I have pasted my code below:
var titleArray:Array = new Array();
var descriptionArray:Array = new Array();
var largeImageArray:Array = new Array();
var thumbnailImageArray:Array = new Array();
var imageNum:Number=0;
var totalImages:Number;
//XML
//load in XML
var XMLURLLoader:URLLoader = new URLLoader();
XMLURLLoader.load(new URLRequest("assets/portfolio/portfolio.xml"));
XMLURLLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(event:Event):void {
var theXMLData:XML=new XML(XMLURLLoader.data);
totalImages=theXMLData.title.length();
for (var i:Number = 0; i < totalImages; i++) {
titleArray.push(theXMLData.title[i]);
descriptionArray.push(theXMLData.description[i]);
largeImageArray.push(theXMLData.largeImage[i]);
thumbnailImageArray.push(theXMLData.thumbImage[i]);
loadThumbnail();
myScrollPane.source=allThumbnails;
//LOAD THE THUMBNAILS
function loadThumbnail():void {
trace(imageNum);
var thumbLoader:Loader = new Loader();
thumbLoader.load(new URLRequest(thumbnailImageArray[imageNum]));
thumbLoader.x = 90*imageNum;
//stores the appropriate info for thumbnail
var thisLargeImage:String = largeImageArray[imageNum];
var thisTitle:String = titleArray[imageNum];
var thisDescription:String = descriptionArray[imageNum];
thumbLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, thumbLoaded);
function thumbLoaded(event:Event):void {
//add the thumbnails to the allThumbnails instance
allThumbnails.addChild(thumbLoader);
allThumbnails.buttonMode = true;
myScrollPane.update();
thumbLoader.addEventListener(MouseEvent.CLICK, loadMainImage1);
function loadMainImage1(event:MouseEvent):void {
largeUILoader.source=thisLargeImage;
selectedTitle.text=thisTitle;
selectedDesc.text=thisDescription;
//add to imageNum (1);
imageNum++;
if (imageNum<totalImages) {
loadThumbnail();
I know my error has something to do with this part of the code:
//stores the appropriate info for thumbnail
var thisLargeImage:String = largeImageArray[imageNum];
var thisTitle:String = titleArray[imageNum];
var thisDescription:String = descriptionArray[imageNum];
but I can't figure out what's wrong. When I test my movie, everything functions correctly except when I click on a different thumbnail, the proper description does not load. My xml file is set up correctly. Here is a bit of that code:
<?xml version="1.0" encoding="UTF-8"?>
<portfolio>

<title>Spark Your Imagination Ad</title>
<![CDATA[<description>These black & white ads were designed to run in the trade publication The Green Sheet in the Merchant Acquiring Industry</description>]]>

<largeImage>assets/portfolio/lg/2.jpg</largeImage>
<thumbImage>assets/portfolio/thumbs/2.jpg</thumbImage>
</portfolio>
The only thing different with my xml code is that in the tutorial I am following, the <description></description> tags are on the outside of the CDATA tags (which I have seen examples of both)... but when I put the code that way, it causes breaks in my code at the first special character I use.
Any help is appreciated. Thanks, Jen

Python/C# class inherit from Labview Class

Hello everyone,
Is there any way to subclass a labview object with a class written in another langauge say python or a .net language?
For example, I have a generic Camera.lvclass that I would like to implement for a specific camera. However, I would like to code the subclass in python.
My first thought was to write the python code, and then wrap it in the labview subclass using the labPython tool. Is there a better way?
Thanks
labjunky.

no. a class can only inherit from one class. you can implement multiple interfaces.

The code I say to add is to troubleshoot the problem, it will not solve it, but it could help lead to solving it if the file is able to compile. Does the trace show up in your output panel? If so, what does it indicate?
You should also go into your Flash section of the Publish Settings and select the option to Permit Debugging... that can help by adding a line number to the error message.
What is the 'door' object that is associated with the 'back' object? Does it exist in a frame that is not present when you try to run the file? If so, check to make sure that it has its instance name assigned in every keyframe it occupies.

CS3 All Buttons give error #2007: Parameter child must be non-null

Using CS3 actionscript all buttons give the following code. I
have tried it myself and used the examples with CS3 and on
livedocs.
Here is the button code:*************************
import fl.controls.Button;
var myButton:Button = new Button();
myButton.toggle = true;
myButton.move(10, 10);
myButton.addEventListener(Event.CHANGE, changeHandler);
addChild(myButton);
function changeHandler(event:Event):void {
trace("Button toggled (selected:" +
event.currentTarget.selected + ")");
**************Error ***************************
TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/addChildAt()
at
fl.controls::BaseButton/fl.controls:BaseButton::drawBackground()
at fl.controls::LabelButton/fl.controls:LabelButton::draw()
at fl.controls::Button/fl.controls:Button::draw()
at fl.core::UIComponent/::callLaterDispatcher()
Button toggled (selected:true)
Can anyone help me with correcting this problem. I can't find
it by googling, searching livedocs, help, etc.

Thanks that worked. I didn't add other components directly to
the library, just called them in the actionscript. Do you know why
the button would be different?

Parse errors while creating a Web service from Java class!

Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
"Validation failed.
The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
import java.io.*;
import java.util.*;
class isPrime
public static void main (String args[])
Scanner reader = new Scanner(System.in);
int n;
System.out.println ("Enter a number you want to know is it prime or not");
n=reader.nextInt();
if (isPrime(n))
System.out.println ("True");
else
System.out.println ("False");
static boolean isPrime (int n)
int i=2;
while (i<=n-1)
if (n%i==0)
return false;
i++;
return true;
}

Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
Regards.

TypeError: Error #1006 - Removing MovieClip from the stage

I have a movie clip that is called to the stage and once the movieclip is finished it calls a function that removes it from the stage. The code works but I get an error message about 4 seconds after the movie clip ends.
Here’s the error message:
TypeError: Error #1006: exitWordMicroscopic is not a function.
                at ASvocabulary_microscopic/frame110()[ASvocabulary_microscopic::frame110:1]
Here’s the stage code:
//************************Removes the movieclip from the stage and enables the button.*************************
function exitWordMicroscopic():void
                bnt_vocab_microscopic.mouseEnabled = true;
                removeChild(word_Microscopic);
//******************************Stage buttons**************************************
stage.addEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
function goButtonsHomeRead_1(event:MouseEvent):void
                //Vocabulary buttons
                if (event.target == bnt_vocab_microscopic)
                                bnt_vocab_microscopic.mouseEnabled = false;
                                SoundMixer.stopAll();
                                addChild(word_Microscopic);
                                word_Microscopic.x = 47;
                                word_Microscopic.y = 120;
Here’s the code inside the movie clip. This is what the error message is referring to:
//****************** Calls function to remove itself from the stage****************************
Object(parent).exitWordMicroscopic();
What am I doing wrong?

Here' how the code looks now:
Objective: To remove the current movieclip while it's playing so that it does not show on the next (or previous) frame.
Here’s the stage code:
var word_Microscopic:ASvocabulary_microscopic = new ASvocabulary_microscopic();
//Removes the movieclip from the stage and enables the button.
function exitWordMicroscopic():void
    bnt_vocab_microscopic.mouseEnabled = true;
    removeChild(word_Microscopic);
//******************************Stage buttons**************************************
stage.addEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
function goButtonsHomeRead_1(event:MouseEvent):void
    //Vocabulary buttons
    if (event.target == bnt_vocab_microscopic)
        SoundMixer.stopAll();
        bnt_vocab_microscopic.mouseEnabled = false;
        addChild(word_Microscopic);
        word_Microscopic.x = 47;
        word_Microscopic.y = 120;
        word_Microscopic.play();
//This button takes the user to the Main Screen
    if (event.target == bnt_ReadGoHome_1)
       // exitWordMicroscopic(); [If I use this function I get this error ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.]
        SoundMixer.stopAll();
        gotoAndPlay("1","Main");
        stage.removeEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
//This takes the user to the next frame.
if (event.target == GoNext_1)
        SoundMixer.stopAll();
        gotoAndPlay("2");
        stage.removeEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
Here’s the code inside the movie clip.
//****************** Calls function to remove itself from the stage****************************
Object(parent).exitWordMicroscopic();
