It's too complicate to explain but I'll give you an example
I have an AS3 ResultEvent Object and this object has several propeties which can be accessed by this like:event.result.name or event.result.age and, I have this String variable: eventProperty:String that contains "name" or "age" How do I access to event.result. with the variable?
Using e4x in flex:
var attr : String = "foo";
var xml : XML =
<resultSet>
<node foo="1"/>
</resultSet>;
How can I use the variable "attr" to access
xml.node.@foo
I thought I could do it with
xml.node.@[attr]
But this doesn't seem to work. How can I access this attribute by a dynamic value like this?
Both
xml.node.@[attr];
and
xml.node.attribute(attr);
work, as Constantiner suggested.
Updates:
Say I have an XMLList in this form:
var bar:XML =
<resultSet>
<node>value</node>
</resultSet>;
I want to filter the original xml above by matching "foo" attributes with the "value" from node in bar.
Essentially I want a sublist of the original xml such that
xml.node.@foo == bar.value
for each xml row in the original value
As Constantiner mentioned, I can filter the original list by the value in foo, but what if I want to filter on multiple values?
Can I do something like:
xml.node.(bar.node.contains(attribute(foo)) ? attribute(foo) : null);
Or perhaps a cleaner method instead of the null?
I try to do preloder in Flex for my project written in Flash. I make this with the help of this site link text My Flash project have next source in main class called Game
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown);

Flex application work but Flash application does not react to button presses
how I can make preloader and work buttons together
I am building a AS3 only project and got runtime error that said "Cannot access a property or method of a null object reference."
Here is my code:
main.as
public class videoMain extends Sprite{
private var videoPlayer:Player;
public function videoMain (){
[code]....
TypeError: Error #1009: Cannot access a property or method of a null object reference have a mxml file that has actionscript inside of it, I'm trying to call a function in a button outside of this actionscript in the same mxml file. I'm calling the public function cancel(); like this click="cancel();" but i'm getting an error 1009 that I can't access a property or method of a null object reference
Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox
[code].....
I changed my html template to include flashvars like so:
if (hasRequestedVersion) {
// if we've detected an acceptable version
// embed the Flash Content SWF when all tests are passed
[code]...
And I am trying to access them in my app like so:private static var _PID:uint = Application.application.parameters.product_id;
But I am getting this error:
Error #1009: Cannot access a property or method of a null object reference.
I am trying to use a button in my init() method.

<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"

Now when I try to do something with my button I get the error mentioned. I am assuming maybe it has not loaded yet?

I have a flex application which use DragManager.When I'm loading this application into flash application and trying to use drag'n'drop functions - I get an error:

function fn1(var2)
{
//here i want to trace the name of var1....ie output: "var1"
}
fn1(var1);
how to trace the variable name i am passing to fn1 (ie. var1) as string?
ie. output shoud be
"var1"
ie i want to trace the name of argument variable i am passing
Is there a way to access a variable via a String? Something like this:
HTML Code:
var myVar1:Int = 1
var myVar2:Int = "myVar1" as variable name
This is obviously doesn't work (and in this case pointless), but is there a way to do this?
I'm new to flex and actionscript. I'm trying to create a small flex app that has multiple states, but if I have nested containers, it looks like some of the objects are not getting initialized when I expected them to be, even when I have the creationPolicy set to "all."I've reduced the issue to a small example, with a commented block showing when it does work.sing the existing code, I get this error: "TypeError: Error #1009: Cannot access a property or method of a null object reference at main/init()" and the event handlers are not installed.If I instead use the commented block, which has the Panel and VBox elements removed, it does work.I know I could add a click attribute to the mxml elements, but this is just a simplified example, and I'm more interested knowing why the objects are not initialized when the app loads.

Here is my main code:
[Code]....
I run my code, it will give me a "Cannot access a property or method of a null object reference" error. I double checked, I realized when the program run until the component file up to the accessing dataGridData variable, that dataGridData variable is null at that time. That is probably flex initiate the component file before it send or get the xml data from server in main. Which cause the variable is still null at the mean time.
I have this custom class which extends EventDispatcher
private var assetsManager:AssetManager;
And this running on creationComplete
GeneralUtils.parentComponent = this;
this.assetsManager.addEventListener(AssetEvent.ASSETS_LOADED,OnAssetsLoaded);
this.LoadConfigFile();
I'm getting 1009 errors on the second line. I've been looking at this for a while and can't figure out what it can't find. The OnAssetsLoaded function is there.
There are a three public variable

my goal is to keep my output window organized so i can follow all my traces more easily. so i wrote a couple of custom functions to achieve that. one of them would be: to more easily trace the following variable for example

I'm trying to change a static variable in the class's constructor. At the start I have:
public static var mainReference:Main;
public static var timerReference:Timer;
public var timer:Timer = new Timer(1000);
This is so my static functions can access main and timer. At Main's constructor I have:
mainReference = this;
timerReference = timer;
The problem is, the first gives no error when I compile it, but the second tells me Access of undefined property (timerReference).
Assign an event listener to a protected timer variable in the parent class.
I am working with Adobe LCCS, and created a BatonProperty which implements Baton
Now, Baton has a protected timer variable declared like this, and for some reason, I am unable to get access to this _autoPutDownTimer, from a BatonProperty instance.[code]...

View 1 RepliesI'm trying to update a dynamic text field based on the scaleY value of a mask that I'm tweening using TweenLite. Example: as the mask scales from 1 to 0, the date in my text field would change from 1970 to 1980. But it doesn't want to broadcast that scaleY property during the tween.
