Php :: Multiple Calls To Amfphp Using Singleton Pattern On Netconnection?
Feb 23, 2012
I'm trying to call AMFPHP two times on a single ActionScript method and what happen is that only the first call succeed. The second one doesn't return an error, doesn't alertsanything, it is more likely that it doesn't even happens and I'm not sure why.Here is an example:
public function editSomething():void{
if(dgChild.selectedIndex == -1){
Alert.show("You need to select a register in order to edit it.");

I'm currently using AMFPHP 1.9 to make a simple flash game which uses a game server.Sometimes, I get this error (BadVersion) when there are simultaneous calls to the server.I've searched the web for some of the answers to this problem, and it seems they were answered back in 2004.Is there an updated version of how to solve this problem?I tried to change the globals.php parameters to use absolute path, like performing the below:
//$servicesPath = "services/";
//change to
$servicesPath = "/httpdocs/Flash/AMFPHP/services/";

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?

I 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.

UPDATE: Now I've moved the AMFConnection var declaration to outside the functions in Main, and commented out some trace() commands, and now it gives new errors:
Error #2044: Unhandled NetStatusEvent:. level=error, code=NetConnection.Call.BadVersion
at AMFConnection/init()[/Users/Jan/Downloads/amfphp1/AMFConnection.as:32]
at AMFConnection()[/Users/Jan/Downloads/amfphp1/AMFConnection.as:23]
[code]...
I'm trying to connect to AMFPHP on a server (with Flash AS3), and the swf borks when it reaches the .connect() stage. To make things easier (?) and more reusable (?), I've put all the NetConnection mechanics into a separate class, AMFConnection, which I call from the Main document class like this (details changed):
public function testConnection(e:*=null):void {
var conn:AMFConnection = new AMFConnection();
conn.table = "some_table";
[code]...
AMFConnection actually starts the connection and calls the AMFPHP service with the function gogogo(), and here's where the connect() NetConnection function just won't work. Here's the main section of the AMFConncection class
private var _netConnection:NetConnection;
private var _responder:Responder;
function AMFConnection()
[code]...
It also fails to display the stage, instead showing the loading dots. Now, eventually I'm going to move this application to the same server as the AMFPHP service, but even when I try it there with a relative url, instead of an absolute one, it still breaks down at connect(). I've tried changing the publish settings from local only to network only, to no avail.

In one of our project we are using flex for front end, blazeds/java in the backend. Its an existing code where services are prewritten. I have to make calls to 3 services in the backend (basically 3 remote objects) and get their result and store the result in an object and show the data of this object in a view.
Now in front end we are using Flex and Parsley Framework. I was thinking of the following approaches.
1) Making commands for each service call and storing the result in a shared object (model) and then displaying this model in the view. In this approach the problem is some services are needed in some other web pages, but they donot need the same model. How should i handle this scenario ? Should i make a asynchronous remote call and fetch the result and then again dispatch and event with the event object storing the result.
2) Making a service call , wait for the result then make another call and wait for the result and then make other call, not sure if this is the right way ?

If I'm streaming live video and chatting in an FMS app, should each component have its own instance of NetConnection or should they share one? Was thinking perhaps the quality of the live video stream would be hurt in a sharing situation but am not sure the architecture works like that.
From a development standpoint, I'd like to make one NetConnection instance in my main application file and connect with it. Then, when successfully connected, I'd like to pass that connection into any custom components that need it.

I 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 made an mc which on being hovered makes a wave. The problem is that I can't think how to apply the code on about 15 mc's. I used the main timeline for coding purpose. Now I want to apply the same waving pattern to the other 14 mc's. I tried the for loop but couldn't get it to work because of the variables involved.
Here's my code-
k = 100;
t = 0;
ascend = true;
waver = false;
waving = false;

i'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}.
the pattern...
{url===http://somesite.com, text===replacement text}
and the intended result...
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.

How many instances of Video, NetStream and NetConnection would be needed for multiple videos?Not sure that's the right question but essentially here's the objective:Currently, I'm working on an interactive product tour, parts of which are to consist of short video clips, each covering a feature. While only one such clip will be playing at any given time, I'd like put them all at the application's fingertips as part of the initial preloading process before launching into it. The idea is to provide a seamless instant-play user experience without hitting the breaks before individual segments.Honestly, I hate pre-caching crap into user's memory, especially when some of that content may be potentially ignored. However, given the target audience, it is reasonable to predict that all features will be explored most of the time, so it's a fair compromise to me. Besides, I went to great lengths to keep the mp4s' sizes to the minimum.Anyway, I'm guessing you don't really need more than one instance of the Video class but how many NetStreams and NetConnections do I you need, probably one of each per video, ha?

Are there any known issues (and workarounds) involving multiple calls toExternalInterface.call in ActionScript 2.0?I have 3 functions, each of which calls an external JavaScript function. These 3 functions run nearly back-to-back-to-back. The first time I load the page containing my Flash movie in a browser, I see the effects of all 3 JavaScript functions, as expected. However, once I begin reloading the page a few times, I begin to randomly see the effects of only 1, 2, or 3 of the JavaScript functions. Clearing the browser cache seems to "reset" this cycle, guaranteeing all 3 calls to work again successfully.

Thats the schematic of my the specific area of my program thats causing me trouble. In output i get "C Called" only. I'm guessing that on the return of the super() call to A() then it jumps back to C(), but id expect that the call stack could handle multiple super calls.

I have some code that calls multiple functions for a single movie clip during a single event. For example:
portfolioButton.onPress = function()
{
redClip.easeX(180, speed);
redClip.easeHeight(194, speed);
}
The problem is only the first function call works (redClip.easeX(180, speed)). Is there a way for both function calls to execute?

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'm on Flash Builder 4.5 and I'm using remote object with amfphp and when I call two method (method1 and method2) at the same time the response of method2 always arrives after method1's response even though method2 is much more faster to return the result.re's the scenario:I set a remote object which refers to a remote php class "Newletter" which contains the sendNewsletter and getProgress methods.Here's the code:-sendNewsletter() reads the email archive and send the newsletter. After each email has sent it writes a log into the database.-getProgress() reads the log wrote by sendNewsletter, counts how many email have been sent, compares it with the total number of the email that have to be sent and return the progress percentageFrom the flex interface the users select a Newsletter to be sent and click on a "send" button which calls a function that calls the sendNewsletter() and then instantiate a loop of calls to getProgress (as you can see when getProgress returns something it calls the setProgress which updates a progress bar and calls getProgress again until the progress percentage reach 100%.
So right after I call sendNewsletter() I call getProgress() on the same remoteClass().sendNewsletter() can take several minutes to complete (in my tests for sending 4 email it takes about 4 seconds so I think that sending thousands of email will take much more!!) and the trouble I'm encountering here is that getProgress() result arrives only after sendNewsletter() concludes its execution while what I would like to achieve is:

I'm developing a Flex application and am having some trouble working with asynchronous calls. This is what I would like to be able do:
[Bindable] var fooTypes : ArrayCollection();
for each (var fooType : FooType in getFooTypes()) {
fooType.fooCount = getFooCountForType(fooType);[code]....
The issue I'm running into is that both getFooTypes and getFooCountForType are asynchronous calls to a web service. I understand how to populate fooTypes by setting a Responder and using ResultEvent, but how can I call another service using the result?

I have a web service written in ColdFusion. In this web service, there are two functions; one is to return all the questions in a quiz and the other one is to return all the answer selections to the questions in a quiz.
[Bindable]
private var questionArray:ArrayCollection;
private var cfquiz:RemoteObject;
[code]....
I have the codes above. loadQuestions is called at creationComplete to retrieve the questions. Things are working fine. What I want to do is to call another function within the same web service, returnAnswers, to return the answer options for a question. Since I have cfquiz associated to the web service already, I was using cfquiz to call returnAnswers. However, there is an event listener associated to cfquiz already, resultHandler is being called when returnAnswers comes back with the results.is it possible to check which function returns the results within resultHandler? If so, how? And second, what is the best way to handle calls to multiple functions within the same web service?

When UILoader pulls in the new image i want to populate the text box with the description of that image. I have got the code working to pull the external text in the first time you go to the page but cannot figure out what to do to make it call the function and pass the right argument every time you click the next or back button.
Attached is my code.
var imageNumber = 1;
var textNumber = 1;
var loader:URLLoader = new URLLoader(new URLRequest("images/description"+textNumber+".txt"));

In 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().

I have a doubt,.... How would you create a Singleton class in Flex...
Is there any convention like the class name should eb Singleton or it should extend any other class.
How many Singleton class can a project have?
Can anyone say the real time usage of a Singleton class?
I am planning to keep my components label texts in a Singleton class... Is it a good approach.

I have a few classes in my project which aren't display objects, but they need to know about the stage of my project (stage.stageWidth, stage.stageHeight). Is there a simple way to pass this information along to my classes without using a Singleton or passing these items in as parameters into the constructor??
