I am trying to serialize & deserialize Vector. using ByteArray
Here is my code:
public static function serializeToString(value:Object):String{
if(value==null){
throw new Error("null isn't a legal serialization candidate");
}
var bytes:ByteArray = new ByteArray();
bytes.writeObject(value);
bytes.position = 0;
return Base64.encodeByteArray( bytes ).toString();
}
public static function readObjectFromStringBytes(value:String):Object{
var result:ByteArray= Base64.decodeToByteArray(value);
result.position=0;
return result.readObject();
}
No matter what I do, I keep having this error:
RangeError: Error #2006: The supplied index is out of bounds.
at flash.utils::ByteArray/readObject()
I am dipertly looking for a solution ..
Thanks in advance

I found the problem reason after days of frustration ..
The loader SWF published for player 9, the content SWF published for player 10,
I simply republished the loader for player 10, and the Error #2006 disappeared from the loaded SWF
What I wonder about, is that the content uses Vector. type, which is player 10 feature,
how come it played correctly inside an older loader ?! Why there is no descriptive regarding different player versions ??
Try getting rid of the .position = 0 lines. They aren't necessary and the second one may be what is causing your issue. Also note that toString() is unecessary, as encodeByteArray already returns a String.
In case you want to send or receive the serialized object graph to server-side code without converting to a string first, see this link.

i am having problem in getting child from starling.current.nativestage -
here is my code
var temp:Image = Starling.current.nativeStage.getChildByName("ball"+turn)as Image;
trace(temp.name);
the code "Cannot access a property or method of a null object reference."
am i making any mistake or what?
help me please
Note*i m noob in starling
nativeStage returns the flash Stage. These are flash.display.DisplayObjects. You then cast to a starling.display.Image via as Image. This will always return null.
So, do you really mean the native flash stage, or the starling stage - starling.current.stage?
var temp:Image = Starling.current.stage.getChildByName("ball"+turn)as Image;
trace(temp ? temp.name : "temp is null");
Hey so I am trying to create an air app that generates a PDF for the user to save but am running into issues with PurePDF. Whenever I run the ImageElement.getInstance() method I am returned a runtime error:
Error: Error #2030: End of file was encountered. at flash.utils::ByteArray/readUnsignedByte()
I am still just in the testing stage and am not evening doing anything crazy. This is what my code looks like:
var bd:BitmapData = new BitmapData( 1024,768 );
bd.draw(pdfClip); //A simple movieclip on the stage containing an image
var bytes:ByteArray = bd.getPixels(new Rectangle(1024,768));
var image:ImageElement = ImageElement.getInstance( bytes );
I would be grateful if anyone that has used purePDF can offer any advice, the documentation is extremely limiting.
You should use the "getBitmapDataInstance" instead, because the "getInstance" method is expecting a png encoded bytearray.
ImageElement.getBitmapDataInstance( bitmap );
see also this example:
https://code.google.com/p/purepdf/source/browse/examples/src/ImageBitmapData.as
So I got a very basic class
package {
import flash.display.MovieClip;
public class XmlLang extends MovieClip {
public function XmlLang(num:int) {
trace(num);
}
}
}
and an object at frame one:
var teste:XmlLang = new XmlLang(1);
I'm getting this error:
ArgumentError: Error #1063: Argument count mismatch on XmlLang(). Expected 1, got 0
What am I doing wrong?
Thank you very much for you help.
Something is up with your setup. I took your code and implemented it and it worked.
Here's what I did. I created a new test.fla file in AS3 and put the following code on frame 1 - no object on the stage, just code in frame 1.
import XmlLang;
var teste:XmlLang = new XmlLang(1);
stop();
Created a XmlLang.as file, copying your code exactly and saved it in the same folder as the test.fla. Compiled and got a trace of 1
So I'm not exactly sure what's going on. What version of Flash are you running?
Not sure if this was your case, but for future googlers: you get this error message when you're trying to initialize a vector but then forget the new keyword.
So this:
var something:Vector.<Something> = Vector.<Something>();
Will give you an error saying that Something had an argument count mismatch. The correct line is:
var something:Vector.<Something> = new Vector.<Something>();
Difficult error to get at a glance. Took me a few minutes to find it in my code, especially because it doesn't really give you the error line.
I expect you have an instance of XmlLang located on stage, that will be constructed using a constructor with 0 parameters, like an ordinary MovieClip. To check for this, change the constructor header to this:
public function XmlLang(num:int = 0) {
This way, if something will instantiate an XmlLang without a parameter supplied, the new instance will receive a 0 (the default value) as parameter. And then you check your trace output, I am expecting one or more zeroes appear, followed by an 1.
UPDATE: Now I've moved the AMFConnection var declaration to outside the functions in Main, and commented out some trace() commands, and now it gives new errors:
Error #2044: Unhandled NetStatusEvent:. level=error, code=NetConnection.Call.BadVersion
at AMFConnection/init()[/Users/Jan/Downloads/amfphp1/AMFConnection.as:32]
at AMFConnection()[/Users/Jan/Downloads/amfphp1/AMFConnection.as:23]
at Main/testConnection()[/Users/Jan/Downloads/amfphp1/Main.as:14]
at Main()[/Users/Jan/Downloads/amfphp1/Main.as:10]
All of these essentially point to AMFConnection's NetConnection initialisation: _netConnection = new NetConnection(); (where _netConnection is declared at the beginning of the class)
I'm trying to connect to AMFPHP on a server (with Flash AS3), and the swf borks when it reaches the .connect() stage. To make things easier (?) and more reusable (?), I've put all the NetConnection mechanics into a separate class, AMFConnection, which I call from the Main document class like this (details changed):
public function testConnection(e:*=null):void {
var conn:AMFConnection = new AMFConnection();
conn.table = "some_table";
conn.selections = "*";
conn.conditionals = "WHERE something = 'something'";
conn.service = "QueryAMF";
conn.method = "makeQuery";
conn.displayText = txt;
conn.gogogo("http://www.someplace.com/Amfphp");
}
AMFConnection actually starts the connection and calls the AMFPHP service with the function gogogo(), and here's where the connect() NetConnection function just won't work. Here's the main section of the AMFConncection class
private var _netConnection:NetConnection;
private var _responder:Responder;
function AMFConnection()
{
init();
}
private function init(e:* = null)
{
_netConnection = new NetConnection();
_responder = new Responder(uponResult);
}
public function gogogo(url:String):void {
trace(url);
_netConnection.connect(url);
_netConnection.call(String(service+"/"+method), new Responder(onResult, null), table, selections, conditionals);
}
A quick debug session reveals the below errors:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at AMFConnection/gogogo()[AMFConnection.as:44]
at Main/testConnection()[Main.as:20]
at Main()[Main.as:8]
Where: Main.as:20 = conn.gogogo(...), and AMFConnection.as:44 = _netConnection.connect(url);
It also fails to display the stage, instead showing the loading dots. Now, eventually I'm going to move this application to the same server as the AMFPHP service, but even when I try it there with a relative url, instead of an absolute one, it still breaks down at connect(). I've tried changing the publish settings from local only to network only, to no avail.
Any clues? Know a better way to connect to AMFPHP locally?
Cheers in advance!

P.S. Post updated, see top of page.
first, i prefer to use a php file which contains my sql and params. but hey...
The most obvious reason why you might get this error would be a fault in the url i guess. I believe that the standaard gateway.php is written without a capital G. and does not situate itself in the core folder but in the amfphp folder. but then again I don't know what you have altered.
Your _netConnection must be null, and you call connect() method on null reference, so you finish with NullPointerException. Show us how you initialize _netConnnection :).
Ok, I basically remade the thing, and after a couple of hours, it decided to work. I'm not sure how, but... eh.
Thanks all for your help
I'm having quite some trouble to try and get an app I wrote in AS2 to AS3. The reason I need to go to AS3 is something icky, so I won't go into detail about it.
I've got 90% of the application running with the new code.
Now I've come to the point where I have to convert this code from AS2,
function setAnimation(theObject,id)
{
theObject.vensterid=id;
theObject.onEnterFrame = function()
{
var myHoriTween:Tween = new Tween (this,"_x",Strong.easeOut,this._x,(130+((theObject.vensterid-frameno)*260)),1,true);
}
}
setAnimation(venster0,0);
, to AS3. My attempt of doing this ended up like
function setAnimation(anObject,id) {
var theObject = this[anObject];
theObject.vensterid=id;
function slideHorizontal(event:Event)
{
var myTween:Tween = new Tween (theObject,"x",Strong.easeOut,this.x,(130+((theObject.vensterid-frameno)*260)),1,true);
}
theObject.addEventListener(Event.ENTER_FRAME,slideHorizontal);
}
setAnimation(venster0,0);
and gives me the following non-error (it doesn't show as a compiler error, but as output):
TypeError: Error #1010: A term is undefined and has no properties.
at sliding_windows_as3_fla::SlideMenu_1/setAnimation()
at sliding_windows_as3_fla::SlideMenu_1/frame1()
I think this is very strange since it doesn't say anything about which term (and there are quite a lot) and googling didn't find me an explanation either.
I didn't get the chance to test your code, because it's difficult to set up a context for it, but my thoughts would be:
You should declare the parameter types: function setAnimation(anObject:Object,id:uint):void. It's at least good practice.
var theObject = this[anObject]; is completely unnecessary if your variable anObject is an object. I think var theObject = this[anObject]; doesn't work, theObject ends up being null and that's why you get your error. If you have declared a variable called venster0, that is the instance of a class that extends Object, then you can pass the reference to it without any other trouble.
Depending on the object you work with, theObject.vensterid=id; might not work. The class that theObject instances must have the 'vensterid' property, or you will get `1119: Access of possibly undefined property vensterid through a reference with static type ...
I think your problem here is following string:
var theObject = this[anObject];
Just replace it with
var theObject = anObject;
I hope that's what you need.
Alternatively instead of
setAnimation(venster0,0);
you could pass an instance name (i.e. String):
setAnimation("venster0",0);
That will work because by this['propertyname'] you are actually accessing Object's property by name.
Just going to throw out that using the built-in Tween classes in Flash/Flex is a pain. Look into using Tweening libraries instead: Tweener, TweenLite, etc. They are much easier to work with, and you don't have to worry about maintaining references until the Tween completes.
