The use I have for it is for storing user credentials, and calling a transfer object that functions as a sort of "cache" for the current session in all of the flex modules.
Thinking about objects that have to be present in every module. Is there any alternative to a singleton instance for this?

View 1 RepliesI am trying to use an existing link with a flash file that is functional to also link to another page at the same time. Basically I am using Joomla and I have a flash file that has menus and pictures and such. I want to be able to click on a link within the flash file and still have it do its given function of pulling up an image or opening another menu or whatever the current function of that link is. The problem I am having is that I also want this link when clicked to navigate to a specific url to show aditional content on one of the Joolma pages.when one of the links in the flash file is click and it pulls up a specific image within the flash file.I want it to also pull up text or other content below my flash file that goes along with the image.

View 1 RepliesI am currently migrating from RubyAMF to PyAMF. In RubyAMF you can return a FaultObject deliberately like so:
render :amf => FaultObject.new("Thats not your pie!")
Is there comparable functionality in PyAMF? I've searched the docs and can't find any mention of it.
When writing a custom layout for a List, what considerations need to be given for using the horizontalScrollPosition / verticalScrollPosition properties on the LayoutBase class itself (as opposed to the corresponding properties on the layoutTarget)
Looking at the HorizontalLayout class as an example, it always references and updates layoutTarget.horizontalScrollPosition. Is the horizontalScrollPosition of the LayoutBase class ever referenced / used?
What's the relationship between the property on the layout instance, vs the property on the layoutTarget instance, and when should each be used?
If you want to use content on another server, that server needs to host a crossdomain.xml file allowing access. If this file isn't there, flash won't let you access it. Given that it's easy enough to just write a proxy (say a php script that curls the external URLs) what is the purpose of this restriction? It seems that the content is still 100% available to external people, but there is just one extra hoop to jump through.

View 9 Replieswhats the purpose of having to have an extra class such as abstract class in Flash where the methods has no implementation,but the subclasses declare those implementations.The advantage of having the methods declared in subclass than the superclass is that it would not affect the other subclasses when there are certain changes.That makes me wonder, isn't it better not to extend(inherit) empty methods but directly create a class as its own? unless there is something that the child could use from parent.Anyone could give me examples of how applicable using abstract classes/interfaces?

View 1 RepliesI'm trying to make a variation on Array for a very specific purpose. When I have the following:
public class TileArray extends Array {
// Intentionally empty - I get the error regardless
}
Why can't I do this?
var tl:TileArray = [1,2,3];
despite the fact that I can do this
var ar:Array = [1,2,3];
The error I receive is this: Implicit coercion of a value with static type Array to a possibly unrelated type
I'm using Actionscript. I'm currently working on a small game - In the game, I'm using a global variable called _global.battle to track, at where the player is (more difficult battles are being unlocked with story progression). I want the player to get from a town to a map where - depending on the variable, a certain number of battle locations is selectable. I put the following code on the button that let's you access the map:
ActionScript Code:
gate_btn.onPress = function(){
if (_global.battle = 1){gotoAndStop("map",1);}
else if (_global.battle = 2){gotoAndStop("map",2);}
else if (_global.battle = 3){gotoAndStop("map",3);}
else if (_global.battle = 4){gotoAndStop("map",4);}
else if (_global.battle = 5){gotoAndStop("map",5);}
}
My problem is the following: if I switch the variable to 2 (or higher), the button ignores this and sends me to "map",1 - and assigns the variable the value 1 again. I have no idea why it does that. I don't have any other code with this variable except in my title screen, where I give it the value 1 and on another screen, where I give it the value 2 (by doing this: _global.battle = 2;).
Can RSS Feeds be inserted into Flash?
I would like to create an animation whose sole purpose is to scroll a feed (like CNN), and that would change the source feed every 10 minutes.
I've been going over several tutorials and whatnot and I'm confused on the point of movie clip symbols and motion tweens. To me using the other tweens and symbols are "easier". Can someone explain to me why they're so beneficial to have been added to CS4/CS5? Except I understand that movie clip symbols can be adjusted using the 3D tools but is that the only difference?
View 1 RepliesI'm building a networked client app with Flash Builder, and would like to be able to set environmental variables or #define's such as server's hostname and port. For debugging purposes I want to connect the client with different servers (and for other devs too). In C/C++ I'd define TEST_PORT=8888 or something in the IDE or build environment, that way I wouldn't need to commit a settings file along with the client. But not sure what's the standard for Flash Builder.
View 1 RepliesI'm looking for a really really small linux distribution or process of making my own that's sole purpose is to get an air application to launch full screen and stay there; Essentially I'm building a home kitchen computer that runs entirely as an AIR app.
I have looked into using windows xp; and windows xp embedded but they pose so many issues I figured I'd try modern linux.
I have also seen TinyCore Linux which looks interestingly small but not sure what issues that poses in regards to running AIR and "hardware" accelerated display. I've also thought about stripping down an Ubuntu installation but I'm sure somebody must have done this already; google is just failing me right now.

I am looking at the singleton design pattern and trying to really understand what is going on here. But I have some questions that it would seem my logic and/or the way I am reading this is wrong. Take the following code for example
[Code]...
I can't understand why should I even use the Singleton pattern in ActionScript 3. Can anyone explain me this? Maybe I just don't understand the purpose of it. I mean how it differs from other patterns? How it works? I checked the PureMVC source and it's full of Singletons. Why are they using them in the View, Module, Controller?
View 2 RepliesIn the Singleton design pattern you can throw a runtime error if the instance has already been created. But this doesn't work when your singleton class extends another class and has to call super() in its constructor, because (for some reason) you cannot call super() if you've already called throw(), or in fact, you cannot compile code that has a potential call to throw() (for example, in an IF statement) that comes BEFORE that call to super().

How to make it that loaded swf use Singlenton of main.swf ?
I did
ActionScript Code:
var lc:LoaderContext = new LoaderContext();
lc.applicationDomain = ApplicationDomain.currentDomain;
myLoader.load( new URLRequest("http/127.0.0.1/loaded.swf"),lc);
anyway I have 2 different Singlenton classes one comes with loaded.swf another in main.swf and variables not shared
is any way I can merge this values?
