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 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'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 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?

View 1 RepliesI 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 1 RepliesI have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes to the destination in Flex, the time request can be of up to 3 seconds.

I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added.

Is there a way to add authorization header to the subsequent requests as well?
