I haven't found the best process is integrating SWFAddress. I've used it on just about every project since it came out, but I rarely have something reusable, and integrating SWFAddress is one of the more time/thought intensive tasks in the dev of a project.

View 1 RepliesI have an application that takes the user through a set of steps, configuring a product, say about 10+ screens. With options to go back, skip to a certain point etc. I need to fade between these steps, and also have language switches available at any point.
I was thinking of using an MVC style pattern, having a master view that accepts a 'next view' and fades it in, removing the old.
It feels bloated to have 10+ separate view classes, using similar components for this task, so was wondering what other approaches there are that I should look into? or one that is suited for this kind of application
I'm still studying OOP designs, so what's the best way to achieve an inventory for a simple flash game? It seems that more than one design pattern could deliver some kind of an inventory but I would lose the flexibility if I try to adapt it somehow without a good knowledge about the subject. For money to buy what is available in an inventory I thought of Singleton. If there's enough cash earned while playing the game, then one can buy new skills. Maybe decorator pattern could list many thumbnails as buttons, and clicking on it applies new features and skills to the character.
View 1 RepliesI am not able to understand, why a static class cannot replace a Singleton design pattern .
Cannot a static class, can be used to ensure, the class is never/once only, instantiated. Because that is the facility "static" key words provide , however it doesnot allow instantiation, but that is much similar to the limitation of instantiation once only.

There are many times that I've needed to execute some code after a number of events have fired, and I've come up with counters and such but I feel there must be a better way.For example, say five files need to be loaded, after which a UI component will become active.If I set up a counter that increments each time a file is requested, then decrements each time one has loaded, I run the risk that the first two or three files may somehow get completely loaded before my code gets around to requesting the fourth and fifth, which would mean that my counter would be at zero when I still have two files to load, thus allowing the UI component to be prematurely activated.
There are some cases where you could know the number that need to be loaded before the requests go out, but it's possible that the first file contains the paths (and therefore the number of) files.And this file-loading scenario is only an example of the pattern I'm trying to explain.)
I've got this issue implementing the Factory method. Following is the snippet of the the main chart class which calls ChartFactory's method to attain the proper object. I Type Cast chartobject so as to be able to call the Show method; I am apprehensive about that as well.
container = new VBox();
container.percentWidth = 100;
container.percentHeight = 100;
super.media.addChild(container);
chartObject = new ChartBase();

I've been spending some of my spare time working a set of collections for ActionScript 3 but I've hit a pretty serious roadblock for the way ActionScript 3 handles equality checks inside Dictionary Objects. When you compare a key in a dictionary, ActionScript uses the === operator to perform the comparison, this has a bit of a nasty side effect whereby only references to the same instance will resolve true and not objects of equality. Here's what I mean:

If I place a pattern or object over a 3d object created in CS4, will it affect it by warping it in any way.I'm looking for a way to push a pattern over a 3d object, for the pattern to look like the 3d object is "under" it.
View 2 Repliesi'm trying to search a string for a particular pattern, and replace it with elements from within the pattern... for example..here's the given string...if you want to learn how to use regexp, {url===http://somesite.com, text===click here}.

{url===http://somesite.com, text===replacement text}

if you want to learn how to use regexp, click here.
of course, i'll extract the url and do something else with it... i'm just wondering what the regexp is for that pattern, and how i can extract things from the results returned.

View 2 RepliesI have a Flex frontend connecting via RemoteObject to Zend Framework's Zend Amf. This is my only means to transport data between client layer (Flex) and the application and persistence layers (LAMP with Zend Framework).Some ways I can address security are as follows:
I can address TLS by using mx.messaging.channels.SecureAMFChannel in my services-config.xml file and ensuring Flash player is loaded into a HTTPS wrapper and is in fact using HTTPS since the AMF protocol is layered on top of HTTP RemoteObject has a setCredentials method with which I can pass AMF authentication headers to protect user related data. Assuming TLS was actually secure I can expose methods on the endpoint after authenticating the User.I can protect against cross-site scripting and other FLASH vulnerabilities with a properly set up crossdomain.xml how to I protect my endpoint against another AMF consumer? For instance, if there were another AMF consumer (not Flash so not bound by crossdomain.xml and Flash sandbox security) other than my Flex client that knew my endpoint, what would stop it from using methods that the endpoint exposes?
As far as I know I essentially need a way to authenticate my Flex application against my Zend Amf endpoint. After AMF consumer authentication, I have some of the security mechanisms I mentioned above to protect certain pieces of data (like User authentication). I can not embed some sort of authentication mechanism into my Flex swf because the swf is vulnerable to decompilation (the swf can not be trusted). While sensitive data is protected via User authentication the unprotected data is hardly public but as far as I can tell is totally open for public consumption.

I'm starting a Flex app on a pretty big reporting engine and want to know how best to connect to a Postgres Database. I'd like to create a REST API architecture so I can use the service for more than just the Flex app(mobile possibly).These are my options I've found:
Datatype: either XML, JSON or AMF
Flex Service: HTTPService or WebService
Server(using PHP): ZendAMF, custom json_encode implementation, Zend_Rest_Server
I've got my views all mapped out, and the api functions designed. Basically what I need is advice on which Flex / back-end service combo to provide.

View 1 RepliesIs model injection on the fly possible? In other words,if I ask for a model of the type IPhotoModel, I should get one of its implementations based on the current state of the view. If I am looking at a UserPage,I should get a user-specific implementation of that model.I am looking at a LocationPage,I should get a location-specific implementation.Currently, the only way that I see is introducing a command that specifies the model mapping, with a concrete one based on the current view state ...

I just upgraded out Flex project to use SDK version 4.5.1.21328 and the Flash Builder to version 4.5
All of the sudden, I'm getting several red tags on the Flash Builder: "could not resolve s:State/fx:Script/whatever to a component implementation"
However, the project builds fine with Maven, and seems to work well too.
Does anyone have any information on how to remove these "problems"?
