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:

Flex :: Casting Object From ArrayCollection To Instance Of Custom Class
Jan 28, 2011I 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:
package com.mycompaany.arcc.business {
import flash.utils.describeType;
import mx.collections.ArrayCollection;

Flex :: Type Coercion Error When Casting An Object Loaded In A Different Application Domain
Apr 28, 2011My 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?

Jun 18, 2009I 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?

Actionscript 3 :: Why Is Casting Object (null) Not Null
Mar 6, 2012When 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.

Optimization :: Search Difference Between Array / List Of Object?
Mar 17, 2012Premesis:I am using actionscript with two arraycollection containing object with value to be matched...Let's assume I have two list of elements A and B (no duplicate values) and I need to compare them and remove all the elements present in both, so at the end I should have
in A all the elements that are in A but not in B
in B all the elements that are in B but not in A
now I do something like that:
for (var i:int = 0 ; i < a.length ;)
{
var isFound:Boolean = false;[code].....
I cycle both the array and if I found a match I remove the items from both of the array (and don't increase the loop value so the for cycle progress in a correct way).I was wondering if (and i'm sure there is) there is a better (and less CPU consuming) way to do it...

View 2 RepliesActionscript 3 :: Casting One Type To Another?
Mar 12, 2012I have a base class called Room and a subclass called Attic, and another called Basement.
I have a controller class that has an attribute called CurrentLocation which is type Room. The idea is I want to be able to put Attic or Basement in that property and get it back, then cast that to whatever type it is.
So if on the controller the content is of type Attic, I'm trying to figure out how to explicitly cast it. I thought I knew but its not working... Here's what I thought it would be, borrowing from Java:
var myAttic:Attic = (Attic) Controller.CurrentLocation;
This gives me a syntax error:
1086: Syntax error: expecting semicolon before instance.
So how do you cast implicitly? Or can you? I could swear I've done this before as as3.

AS3 :: Casting A Subclass Into A Parent Variable?
Jan 7, 2010I am calling on different types classes from within a loop. The objects can be of different types so therefore I am using the getDefinitionByName method. here is a piece of my code:
for(var y = 0; y < mapH; y++)
{
brickHolder[y] = new Array();
[Code]....
But I got an error when I tried to call on methods. The interface is blank; doesn't have any methods in it. I am not sure if that makes a difference. But the parent class inherits it and the subclasses inherit the parent class. Can I instead use the parent class?
var brick:ParentBrick2 = ParentBrick2(new classRef());
In a nutshell, what can I do to loosely cast these objects so I am able to use any subclass methods that get called?

ActionScript 2.0 :: Shadow Casting Angle Bug?
Jan 10, 2011Okay so quite an ambiguous title but what I'm trying to do is cast a shadow off shapes from a light source. Simple enough and I have it working but I just can't work out how to fix the problem of when the light source is at a certain angle to the shape I'm casting a shadow from.I know it's the whole 180 to -180 thing, but I just can't think of a work around.I've attached the swf and fla so you can see for yourself.Basically the code works by chucking points of the shape in an array and then arranging the array by the angle of each point from the light source. No big deal. From there it just takes the first and last point in the array and draws a shadow from there. Sketchy for the time being I know, but I just don't understand why it's doing what it is.

May 1, 2007Let's say I have 3 items in the same package:Shouter interface - requires implementers to implement the shout() functionShell class - implements Shouter...this Shell.swf is to be loaded remotely from:ShellLoader class - loads Shell from a remote server, casts it as a Shouter and invokes its shout() function...uses allowDomain in order to cross-domain script.Now let's say ShellLoader.swf lives on and Shell.swf lives on ....I've got a cross-domain policy on Using LoaderContext's ApplicationDomain and SecurityDomain, I'm able to load and cast the Shell object as a Shouter and invoke the shout() function. Everything ok here.
Now let's say ShellLoader is run locally and is localTrusted. Shell.swf still lives on I'm now unable to use SecurityDomain property of LoaderContext within ShellLoader because it is now run locally. Shell.swf now exists in a different ApplicationDomain as my ShellLoader and I get the error "Type Coercion failed" when I try to cast the loader content as a Shouter.Is there anyway to resolve this issue? I believe it will require Shell.swf to be loaded in the same ApplicationDomain as ShellLoader but I don't know any way to do this when ShellLoader is run locally. Perhaps this is prevented in the Flash player on purpose?
