I am trying to learn flex4 from adobe document and I am very confused while using three namespaces.. there is no way i can keep track of when to use what often ending up using fx inside mx or s or similarly making some stupid goofed up combinations of {fx,mx,s}.
Adobe document is huge and i am looking for some good starting point for learning flex .
I worked on a flex application 6-7 months back. We used flex 3.5 sdk. Now we are upgrading our flex app with flex sdk 4/4.1 I am still new to flex development and I have a very basic question related to namespace. I have seen three different namespaces in flex sample applications. What is the purpose of having three diff namespaces? When do I use each of them ?

I'm trying to get data from a namespaced xml file in a flex app. There is a root namespace (xmlns="blah") and another namespace (xmlns:i="blah"), and I'm able to access most tags using the following:
var ns:Namespace = doc.namespace();
var result:XMLList = doc.ns::element;
However, there are several tags that are subject to change in the application, and i'd like to not hardcode them, possibly using the elements method:
var result:XMLList = doc.elements(configuredField);
Is there a way to get elements with namespaces using the elements method, or a similar way to get XML elements in flex using a parameter?
I'm trying to compile an SWC file from a list of given ActionScript classes. I'm using the compc compiler. The problem is that there are so many classes grouped into multiple namespaces that I am finding it very tedious to specify each individual class to be included in the SWC. Is there any easier way of doing this like just simply specifying a root directory of these classes? At the moment I have something like this:

Is there any way to get interface to play along with custom namespace? Example follows.
IHeaderRenderer.as:
public interface IHeaderRenderer{
function set header(value:IHeader):void;
function get header():IHeader;
}

Sorry for all the blabbing. Any cunning ideas how this kind of situation could be handled?
How do i access the 'mx' or 'fl' namespaces in a Flex Builder Actionscript Project? Do I need to include a certain .swc file?

I have seen afew answers to the problem i am having now but mine is that of a nested one.
I have an xml looking like this:

<em>
<type xmlns="http://www.sitcom-project.org/sitcom" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
[Code]....
now, how do i access the element of the implemented_with node?
ofc i could access the xmlList this way:
namespace ns = www.sitcom-project.org/sitcom;
type.ns::model;
but now, how do i access the implemented_with node in the model xmlList? i tried type.ns::model.implemented_with, but didn't work.
I'd like to know if it's possible to store namespaces in an array?Imagine i had infinite namespaces and i'd use "for" to store them automatically, what would i need? i don't think an array would save namespaces as they are.
View 2 RepliesI'm writing some actionscript to provide a flash frontend to an MS Excel spreadsheet. The idea is that the user will be able to press buttons in a flash application, and that will enter data into the spreadsheet (which will be read and written as XML).
The XML of an MS Excel document looks like this:
Code:
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"

I have this XML object, and I need to display parts of it so that the user can copy and paste from it. However, whenever I try to, say, display the category section by doing myXML.category, it puts the namespace information in the attributes of the first <category> tag when it displays the xml. Is there a way to get rid of this?

View 1 RepliesI'm trying to create a property that can be set by extending classed and read publicly.I couldn't think of a good naming convention for a protected property with a public getter, so I tried to do this:
public function get name():String{ return _name; }
protected function set name(string:String):void
{[code]......
However I get the error (when trying to set name in an extending class): 1178: Attempted access of inaccessible property name through a
reference with static type testing:TestComponent.1059: Property is read-only.
If I change the setter to public, it works fine.
Can methods declared with a custom namespace be overwritten?
Code:
// secret.as
package {
public namespace secret = "http://www.example.com/secret";
[Code].....
If I try the above I get "1004: Namespace was not found or is not a compile-time constant." If I remove override I get "VerifyError: Error #1053: Illegal override of test in Extended."
1157: Interface members cannot be declared public, private, protected, or internal.
I'm just curious as to WHY? I don't understand the thinking behind this "law".
Does this perhaps mean that interface properties always need to be public when implemented in the target classes, and produces this error in order to help enforce that law?
I haven't tested if custom namespaces produce the same error. I'll delve deeper into this when I get the time.
Given this:public namespace foo;foo var bar:String = "baz";We can access the property "bar" like so:[code]It gives me the following error: ReferenceError: Error #1069: Property foo::bar not found on MyClass and there is no default value.On further inspection of the foo namespace I can see (in the debugger) that the URI is in the format {package}:{type}/{name}. If I try to replicate this by doing the following:[code]Does anyone know if it is possible to get access to namespaced members like this? I don't have compile time access to the namespace, but I can look up it's uri (and prefix) dynamically at run time.
View 1 RepliesI have the following packages.Within spark I have a class SeCore; and within spark.engine I have SeStepper and SeKeyboard.What I'm trying to achieve is have SeCore as being the only class that can create an instance of SeStepper or SeKeyboard. This can be achieved by moving SeCore into the spark.engine package and making the other two classes internal, but I'd like to have SeCore in the spark package if possible.I've tried making my own namespace to handle this, like so:
package spark.engine
{
import spark.namespaces.spark_core;[code].........
However I get the error: 1116: A user-defined namespace attribute can only be used at the top level of a class definition.
Code:
trace("Hello!");
I'm up late coding and I've come to a halt here's why:
I'm looking (desperately) for something that will explain why my "public class marquePage" is not working properly. I don't have access to the actual file right now - on a friend's computer - but i'll try and make this clear, here it goes :
Code:
// example : (having declared the namespaces at package level and embedded the pictures in separate classes "photosMP", etc)
public var ceNom:Namespace;
public var cetteListe:Array = [photos, dessins, livres, maous];
[Code].....
Somehow, the event listener doesn't want to know about namespaces... in fact, everything comes up ok except that when you click on any of the bookmarks (cetMP), nothing happens at all
Trying to migrate to AS 3.0 here, but are facing a tough time at kick-off: I have a base fla file located in a folder named "game". The "game" folder is in a folder named "northcreek" which again is in a folder named "no". For no other reason than that I read somewhere that this was smart. Anyway, I have in my (document) class under publish settings this: no.northcreek.game.Engine Both my "game.fla" and my "Engine.as" reside in the "game" folder, but I fail to reference my as-class from my fla file. What do I do wrong? It works if I simply remove all namespace names, and only type namespace, but I am trying to do it the right way here...
View 8 RepliesSorry if this has been discussed somewhere else on stackoverflow (I could not find it), or if it is not a "programming" question (more like a discussion). Is it good to avoid using an IDE (Flash Builder, Visual Studio...) while first learning a new framework or language?
[Code]...
I've been Actionscripting for quite a while now, and a lot of the sources I see and books I read talk about something called XML. I understand that its a formatting language used to communicated with servers, and the syntax looks like html.
I have a few books on AS, but I don't really get the XML stuff. Is the idea that I use an XML segment of code in my Flash to import in a document to flash at runtime? Or is it that I can load variables from an external document? I don't have my own server but I do have the ability to upload files to servers, so I could probably make a file that can communicate with an SWF, and I'm told XML is the way...
So does anyone know a good way to learn about XML, and what is actually is and can do?
I am totally new to actionscript (barely could set up the IDE environment for Linux). I have trouble parsing an xml file containing some namespaces. All the tutorials and samples i found online are not working for me. the file looks like this:

I have made a script, and now has come the point when I need to use removechild. Whenever I try this I get an error. After looking at the problem, I think I need to learn more about scope and packages. I think if I put everything in the correct scope, I will be able to use the removechild command. I tried to make all my vars public, so that removechild would work, however I got an error that anything public needs to be in a package. I tried to add the package part to my script, but got the error that packages cant be nested. I tried some other things and still no luck, just more errors.
So, if anyone could point me to a tutorial, or recommend a book or something, that will help teach me about scope and packages, Or if you are feeling patient and generous, and you think you could explain this problem to a 5 year old, please explain it to me the way you would to said 5 year old. If you maybe think you can help me out on the script, it can be found here: [URL]
I'm trying to learn how to use flash, and there's only so much I can learn on my own. I looked up some books on various websites, but I don't know which would be the "best" to use for someone completely new to the program.
View 2 RepliesI've gotten far on my own just using online tutorials and dinking around in Flash on my own but my boss(es) are starting to ask for more complex stuff that I simply can't learn by just piecing together my Flash education.I know there's many, many books out there that will teach you Flash but can anyone recommend any particular one(s) that are more concentrated in creating Web elements as opposed to game or animation development?
View 2 RepliesI have created a Flash file with 4 "Fill in the Blank" questions (from the Learning Interactions continued within Flash CS3) at the end. I'm then using the swf file in two different ways. One way simply loads the swf file onto a 'stand-alone' page on my website and it works perfectly.The other way I want to use it is integrated into a more complicated website where I have a Flash File into which various swf files are loaded when needed. In this version the "Control Button" doesn't change to "Check Answer" and "Reset" as it should and the whole question doesn't work. The working version is at url..Select "4 For You to Try" to go directly to Quiz Questions.The non-working version is at url...Go to "Extras" in Menu and select Naming Alkane Isomers, then "4 For You to Try" again.

View 2 RepliesWhat would be a good resource for an experienced programmer to learn Flash?Consider a very seasoned programmer that doesn't require any teaching of programming concepts and that already programmed Javascript. Someone who never created a Flash file, or even know what Flex is. Someone who could probably learn ActionScript in a day but still needs to learn how to apply it.
