i'm using a Rails backend with my App and getting a AsyncToken returned from it (a DB-Call to be specific)As far as i know the AsyncToken returns a result event when done loading all data from the request, this way its possible to make sure all data was loaded before executing some function which uses the data. i tried the following implementation to get the AsyncToken converted into an Array and plotting its objects as strings to the user:
var dataSrv:services.databaseservice.DatabaseService = new services.databaseservice.DatabaseService;
dataSrv.addEventListener(ResultEvent.RESULT, dbListener);
//DBOPERATION returns my AsyncToken
var listData:AsyncToken = dataSrv.DBOPERATION;
But i keep getting a "null object-pointer" error!
I have begun on a list: My reference is null!Stage is null! Convert this code from as 2 to as 3 for me! Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances. Mod note: I do not want this topic pinned, we will use a fresh topic once we have agreed to the content.
View 9 Repliesthe 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.
sometimes I remove child and trace it afterwards and it outputs null although I havent yet set it to null, why is that? and do I need to set it to null also in that case?
Code:
trace(holderArr[loadedThumbs].getChildByName("photo_bg"));
//[object MovieClip]
holderArr[loadedThumbs].removeChild(holderArr[loadedThumbs].getChildByName("photo_bg"));
[Code]....
I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
View 4 RepliesWhen 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 add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.

If I set an Object = null, does that remove all references to the Object's variables assuming there are no external references to said variables? Or do I have to manually set all said variables = null?

It's returning null the first time I click an image however subsequent attempts traces a value (I assume because it is set then, just not when the app loads). how to recognize it when the app loads?

I am getting this error, randomly when I start my application (and it's sub applications). As you can see the stack trace is rather useless, although through the debugger I can see the parent of container (second in the stack) is an MXML class that has a repeater that repeats another component. Therefore I guess the component with the problem is that repeated component, although I am unsure what I can change to stop this from happening. If anyone can give me some insight to the FocusManager or the getFocus() function it would be really handy.[code]

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

Maybe you could school me in how to keep null object references out of complex Classes?
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've written the following custom component, SubNavBar.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" height="100" width="300"
creationComplete="init()">
<mx:Script>
[Code]...
Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?
I have a weird issue (weird because it is specific to one component) with applicationComplete in a fairly simple application. All the UI components are declared in MXML.
