ActionScript 3.0 :: XMLLoader Class Returns NULL In Flash?
May 2, 2008So I dived into AS3 and decided to create an XML Loader class.

Flash :: Calling A Method In Custom XML Class Returns Null?
Sep 7, 2011I am trying to call a method that has some xml functionality and It keeps coming up null.What I am trying to do is; I have a page that has four dynamic text fields that get their content from an xml file. I would like to create a method that will output the contents to display in the dynamic field. Maybe my approach is WAY off here, but my supervisor wants all xml related tasks contained in a xml.as fileMain.as

Arrays :: Accessing Variable From Other Class Returns Null
May 10, 2011I 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.
quizHolder.ansA.ansHud.text = currentLvl.choices[1];

Actionscript 3 :: Casting A Retrieved Mediator With PureMVC As Its Proper Class Returns Null?
Jul 15, 2010I 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.
ActionScript 2.0 :: XMLObject Inside A XmlLoader Utility Class?
Jun 27, 2005i'm using Sephiroth XMLObject to parse Xml and it works nice (handling actions inside the Xml Onload event), but i would like to cut shorter coding writing a class calling Xml and XMLObject, it's possible?. This is an attempt but it doesn't work, or better, Xml file is parsed correctly but is not available.
This is the class:

ActionScript 2.0 :: Get Into The Event Handler 'this' Refers To XmlLoader - Not The Class
Dec 7, 2004I've got a problem... here's an example script:
[Code]...
Ok, so here's the problem. What happens in the above, is that I call 'loadTheXML()', it loads the xml file into xmlLoader and then runs the event handler 'onLoad'. My problem is here: once I get into the event handler 'this' refers to xmlLoader, not the class. Therefore, I have no way of calling wannaCallThis(). How do I call a member function of the class from inside the eventHandler?

ActionScript 3.0 :: Flash Updated CS4, Code Returns #1009: Cannot Access A Property Or Method Of A Null Object Reference?
Jun 7, 2010I 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

Apr 25, 2011I'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

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?

XML :: Flex - ArrayCollection Children Returns Null
Aug 12, 2009I 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

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:

It prints [Object Card] which is how it should be ....

ActionScript 3.0 :: Global Var Returns Null In TextField
Aug 13, 2010I 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;
Flex :: SetFocus To TextInput Field - Returns Null
Jul 3, 2009I 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.
Actionscript 3 :: Casting An Object Using 'as' Returns Null MyObject?
May 3, 2010I 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:

ActionScript 3.0 :: GetBmpData Returns Null When The SWF Is Accessed On The Remote Server?
Mar 17, 2010The 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.

Jan 17, 2011My dynamic text returns null instead of pulling the info i want from my xml file. here is my actionscript and here is my xml. the really weird thing is that i had it working at first. the only thing i changed was the name of the xml file. i used to be called "test" but i needed it to be named something more appropriate so i changed the filename and then i changed the actionscript where it is parsed. so it SHOULD work... but it doesnt. here is what you see instead of the correct info. it seems like the link between the xml and the fla are not communicating with each other anymore, is there anyway i can check to see if the parse is correct?

ActionScript 3.0 :: 'this' Returns Class Not Instance?
Jun 30, 2010I have written a ToggleButton class - a button that toggles an object implementing an Itoggleable interface - a reference to which is stored in the ToggleButtons 'target' property. Toggleable contains a reference to an instance of whichever ToggleButton it is a target of.Now, I can easily create this relationship like so:
PHP Code:
myToggleButton.target = myToggleableObject;
myToggleableObject.toggleButton = myToggleButton;
But what I would like to do is this:
PHP Code:
myToggleButton.target = myToggleableObject;
[code]....
1118: Implicit coercion of a value with static type org.ngfl.template.ui:ToggleButton to a possibly unrelated type ToggleButton.this seems to be saying that the 'this' reference is not returning the instance of the class but the class itself, am I right? Is it not possible to do what I want? It's only one extra line but I'd prefer it that way.

Because The forums have an issue with me posting code...I posted it here: [URL] Based on this code what is the issue here? why is write always returning false and why is load always returning true? (even for files that do not exist). My understanding is that if flash cannot find the file it should write to it will create it and if it cant load said file, then that method should return false.

Actionscript's :: Number Class' ToFixed() Method Returns Strange Values?
Jan 8, 2010I'm doing some calculation with numbers and would like to only print an integer (the number without the decimals).I thought that the toFixed() method of the Number class would do the trick, and it does most of the time. But quite frequently strange values are returned. Here are 2 examples:
Number(0.002).toFixed(0) returns
"0." while
Number(1.002).toFixed(0) returns
"1" (without the period)
Once in a while, Number(0.002).toFixed(0) returns "1"
Needless to say that's not the expected behaviour. Am I not using this method correctly?
*edit: I know I just have to do int(0.002) to get 0 but I'd like to understand that strange behaviour.
