Actionscript 3 :: Casting An Object Using 'as' Returns Null MyObject?
May 3, 2010
I am trying to create a custom object in AS3 to pass information to and from a server, which in this case will be Red5. In the below screenshots you will see that I am able to send a request for an object from as3, and receive it successfully from the java server. However, when I try to cast the received object to my defined objectType using 'as', it takes the value of null. It is my understanding that that when using "as" you're checking to see if your variable is a member of the specified data type. If the variable is not, then null will be returned.
This screenshot illustrates that I am have successfully received my object 'o' from red5 and I am just about to cast it to the (supposedly) identical datatype testObject of LobbyData:

I have a mediator that I've registered for a navigation page:
facade.registerMediator(new NavPageMediator(viewComponent));
I'm trying to retrieve that mediator on another page like so:
var navPageMediator:NavPageMediator = facade.retrieveMediator(NavPageMediator.NAME) as NavPageMediator;
However, that statement returns null. If I try to cast it using the NavPageMediator(facade.retrieveMediator(NavPageMediator.NAME)) syntax instead, I get a TypeError: Error #1034: Type Coercion failed: cannot convert com.website.mvc.view.page::NavPageMediator@237560a1 to com.website.mvc.view.page.NavPageMediator.`
I can't, for the life of me, understand why NavPageMediator@237560a1 would be unable to convert to NavPageMediator, nor what happened in between registering the mediator and retrieving it that caused this. Especially since trace(new NavPageMediator() as NavPageMediator); returns [object NavPageMediator].
Incidentally, and this may be part of my problem, I don't understand what the @hash at the end of the object is (@237560a1). Is it simply an internal identifier for that class instance?
Edit:Left a bit of important info: The SWF in which I instantiate and register the mediator is separate from the SWF in which I try to retrieve it.

When you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.

I am trying to use the following code to convert an object read in from a ByteArray to an Array and store it:
var data:Object = ba.readObject();
var invObjects:Array = data as Array;
In debugging, I find that 'data' is indeed populated with the correct data and takes up memory and is in an Array friendly format. However, invObjects is NULL. How does merely saying 'data as Array' make the holding variable suddenly null?

I have a button at the start and end of a short timeline, it works fine. But when I add a simple MC to the up state of the button, flash gives me this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at BtnWithMCinside_fla::MainTimeline/frame18() The 'mc within a button' method has worked great until that button is placed beyond the first frame. why this is happening and how to fix it?

I have two MC's on stage,
MCmenu is a button array,
MCtext is a collection of text with frame labels. It's labeled as MCtext
The menu buttons tell MCtext to play the frame label as the button clicked. This *used to work*, but Flash was laggy as hell so I updated it. Now the same code returns #1009: Cannot access a property or method of a null object reference. at MCmenu/itemClicked()
Code:
function itemClicked(butn:Event):void {
parent.MCtext.gotoAndPlay(SomeArray[butn.currentTarget.label);
}
I've tried just using a frame number, but still the same #1009
I've tried the Script Assist to target the MC on the stage:
using root.MCtext... still the same #1009
using this.MCtext... returns a #1010

I've got an object inside an object. The child object basically loads a variable from SQL into one of it's own public variables. The SQL works 100%, because it traces out correctly.Now I've wrote a function from the child.as
Code:
public get_var() : String
{
return var_yes_friggin_work;[code].....;
Of course the files arn't called Parent.as and Child.as I've just had to rename them because our work is monitored though checking the internet and I can't delete this form.The FilePathOriginal doesn't output anything unless the string is manually set from the child, does anyone know where I'm going wrong here? (I can't upload all my code because of the monoriting process)

I have an ArrayCollection with following structure (when viewed in debug mode):
[0]
- [0]
-- src
- [1]
-- src
src is the path to an image.
I need to get all of the src's out of the arraycollection. However because of the first (unnamed) node I can't take them in. I've tried ArrayCollection[0].children and save the result in another ArrayCollection, however the new ArrayCollection has 2 Objects in it but no 'src'. There are just 2 null objects
firstArrayCollection is filled with the data as described above.
secondArrayCollection.addItem(firstArrayCollection[0].children);
When viewing the content of secondArrayCollection i see following structure (and data):
[0] null
[1] null

ActionScript Code:
public function draw():Card{
return deck.pop(); //deck = array of Card
}
Does not work. Firstly it runs an error which says
"cannot convert [] to Card"...
Shouldn't it pop() return just ONE element?
Then I correct like this
ActionScript Code:
public function draw():Card{
return deck.pop() as Card;
//deck = array of Card
}
And now I get no errors but the function returns null.... why? If I try this:
ActionScript Code:
public function draw():void{
trace(deck.pop());
//deck = array of Card
}
It prints [Object Card] which is how it should be ....

I have a small issue, which is important for my project though. Namely my global var returns null when I need it. I have a global var class:
Code:
package {
public class Global {
public static var premiseGlobalName:String = new String();
}}
In another class I'm setting this var like so:
Code:
public function onButtonRollOver (event:MouseEvent):void {
Global.premiseGlobalName = "My home";
this.addChild(premiseMenu);
}
The second line in the method calls another class to the stage which uses the global var. I trace the global var:
Code:
public function initPremiseMenu():void {
trace("GLOBAL: " + Global.premiseGlobalName);
}
But it returns an empty value.
I want to use the global var in a textfield like so:
Code:
premiseTip.text = Global.premiseGlobalName;

I have an app where I am looking to make the enter key act like a tab key. I can easily capture the keypress event and setFocus to a textinput field. The problem is figuring out which textinput field to give focus to. I have this code
trace(this.window.focusManager);
//returns TheWindow86.focusManager
trace(this.window.focusManager.getNextFocusManagerComponent());
//returns null
//This is what I was hoping would work
this.window.focusManager.getNextFocusManagerComponent().setFocus();
The code is in a controller class and "this.window" references an instance of a nativeWindow mxml file "TheWindow.mxml". The first trace works as expected, but the second one gives null.

I'm starting a facebook app using iframe method.I am using flex and so far I am able to connect to fb (login and out). Now I am trying to retrieve current logged in user name. In the document I see this function is what I need. Facebook.getSession().A tutorial in adobe site uses desktop api and it works for desktop (AIR app) but not for web app. (yes, i fixed Facebook.getSession() instead of FacebookDesktop.getSession(); Also, I am able to see the uid but not the user. User returns null. uid is a string and user is an object. But on the desktop app,FacebookDesktop.getSession().user.name returns the name perfectly. but on the web, it does not.

I'm currently working on a Flash application that has a sibling AIR equivalent. From inside the Flash application I would like to install the sibling AIR App. Adobe has provided an air.swf (which is also used in the Badge sample) to aid us with the install. I've managed to mimic the behavior of the Badge app butgetApplicationVersion always returns null. Note that I do not have a publisherId.

I did a separate levelData class to be able to flexibly add levels. I was happy with it until my supervisor ordered me to convert my levelData into XML. I did an XML version of the levelData's data (question, answers, correct answer...). I used the old class and converted it so that it fetches the XML.
All seems well, I did traces of my answers array and it printed nicely...
But the headache started when I tried this.
// This code appears in a different class with
// currentLvl:LevelData initialized in the constructor.

The Document class loads a list of external bitmap images. As the images are loaded, the following takes place for each:
Code:
var obj:Object = new Object();
obj.bmpData = bmp.bitmapData;
obj.bmpFilename = bmpFilename;
bmpDataList.push(obj);
As you can see, an object is created and the bitmapData is stored inside of it. This object is added to an array.Later, when a key is pressed, a new instance of a class is created. A function is called that retrieves the appropriate bitmapData and this is passed to the constructor of the new instance. Example:
Code:
//Instance is created:
var newChar:BaseChar = new LowA(getBmpData("a"));[code]....
The problem is that getBmpData returns null when the SWF is accessed on the remote server. Result = no images seen. It works just fine locally.

I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid:
_tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following:
DataGrid(event.currentTarget).selectedItem as Rule
I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class:

My application currently contains a number of Widgets that are managed by a Widget Manager. When the user clicks on a widget (e.g. a Helper widget), the Widget Manager loads the widget into a separate sibling application domain with the following line of code:
wgtInfo.load(null, null, null, moduleFactory); //wgtInfo = IModuleInfo
However, I am unable to use the widget's variables and functions later on. I attempt to find the Helper widget from the Widget Manager's list of widgets, and I do successfully. But when I try to caste the Helper Widget from type IBaseWidget (the interface all widgets share) to type HelperWidget, I receive the following error:
TypeError: Error #1034: Type Coercion failed.....
This is because the application domain of the class trying to use the Helper widget is different from the application domain of the Helper Widget. I tried to fix this by loading all widgets into the same application domain as the loader:
wgtInfo.load(ApplicationDomain.currentDomain, null, null, moduleFactory);
I now get the following error whenever I attempt to load the Helper widget:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
How can I load my Helper widget into a common application domain that is accessible by the other widgets?

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.
