Ajax - Making Multiple Asynchronous Calls To Fetch Result From Multiple Services In The Single Click Of A Button In Flex?
Dec 27, 2010
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 ?

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 flash site that calls a JavaScript function to track events inside of the application, the _gaq is already implemented in the section of the html and it works perfectly fine with one account:
function customTracker(clickEventName)
{
_gaq.push (["_trackPageview", clickEventName]);
}
but now my customer wants to include special events from 3rd party companies and needs these to track into a different GA account. Before I try this out on the live server I wanted to ask if this would work:
function customTracker(clickEventName)
{
_gaq.push(["_setAccount", "UA-XXXXXXXXX-X"]); // the regular account
_gaq.push (["_trackPageview", clickEventName]);

I want a chart that has several separate series running in rows across. They are largely separate charts and should not overlap, but all share the same horizontal datetimeaxis. They don't share the same y-axis, however and that's where I'm getting stuck.I have tried having a linechart series and then a plotchart series, but it will only allow a single <mx:series> per chart without having them inside the same series which as far as I can tell will place the charts on top of each other in the z-axis. I can stack them and have them completely separate charts, but it was proving to be somewhat irritating having them align correctly.
Is there any reasonable way of combining multiple charts into one like this? Basically having rows in a table where each row is a different chart but the columns are consistent. or am I going to be best served just by stacking separate ones? an illustration of what i'm going for is here: http:[url]........

In Flex, I'm making a set of asynchronous calls:
service.method1.send().addResponder(responder1);
service.method2.send().addResponder(responder2);
service.method3.send().addResponder(responder3);
I want to execute some code after all of these service calls have returned (either success or failure, I don't care which). How can I do this?

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 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 Flex application make an asynchronus HTTP request, does it add a special header to the request, like some JavaScript framework does? Something that indicates whether this request is an AJAX call/not.I just want my server side code to return different response format, depending on whether the request is made from browser/flex.

I am creating a "Kiosk" to be used in flash using ActionScript 2.0 with individual scenes. At the end of each scene is an outro and the beginning of each is an intro to give the impression of them all appearing seamless.So on each button I have added the following [code]Frame 180 is where the outro plays to enter the selected scene of that button. I would then like add to this piece of script that I want that button to go to that scene after the outro is played. So it would have something like gotoAndPlay(scene xx);The only other solution I have at the moment would be to make an outro of each scene for each button to jump to but this having 8 scenes it would end up adding up to 64 outros in total.So would there be a solution to simply have each button jump to the one outro then jump to its own scene?

If I have one parent class that instantiates 5-10 different child classes, each of which need to load multiple assets etc, how can I check within that parent class to make sure all of the 5-10 children are loaded & ready to go before telling the program to continue?
The tricky part is that the exact number of those 5-10 classes that are instantiated is determined at runtime, so I can never be certain which I should be waiting on and which not to be waiting on. And just to be clear, these are different modules of sorts, not multiple instances of the same exact class.

How can I populate multiple datagrids in flex with a single datasource that is filtered differently for each datagrid. I'm assigning the event.result from my remote object call to three different array collections, each with its own filter function. When I assign and refresh the filter functions, they each affect all array collections. So, the results of the last array collection refresh end up in all three datagrids.

I have data model (dataProvider as ArrayCollection) i want to display in few views , each view should show filtered data. As you probably know, filterFunction is property of ArrayCollection,so I can't use this solution (unless creating new instance of ArrayCollection for each view on top original and impementing filterFunction).

I have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.

I have a maven project that produces many artifacts. Of course it is kind of against maven best practice (one pom one artifact), but it is Adobe Flex project that produces many *swf modules and it is really makes no sence to create a separate project for each module.
For me it would be very convinient to handle all swf modules as a single zip archive eg. zip archive would be my artifact.
So I am looking for the way to pack and unpack my zip artifact with maven.

I have created a simple mxml file with code as follows:
<s:application..........>
<s:BorderContainer>
<s:SkinnableContainer id="firstRow"/>
<s:SkinnableContainer id="secondRow"/>
<s:SkinnableContainer id="thirdRow"/>
</s:BorderContainer>
</s:application>
Now I want to apply different font size, font color and font type and background color on each row i.e each of the three skinnableContainers.Currently I have defined 3 different skin classes for each of row but I think this is a bad programing. I should create a single skin class for outermost container i.e BorderContainer and any how provide different fonts and background color to all the 3 child containers through that skin class. So, is it possible that I can create single skin class that can provide different decorations to each of the child container.

Is there a way to have a synchronous call to a URL to retrieve the HTML code? If not, is it possible to turn an asynchronous call into a synchronous one using some trick? I can't believe Adobe wouldn't implement this option. I tried looping until the result is back but then the status function never fires making my loop infinite.

I'm a ColdFusion developer and recently started working on a project in Flex. I am getting more and more frustrated with AS and Flex lately. It seems that whatever I'm trying to do is either really hard or impossible while it usually can be done with one line of code in ColdFusion. I'm still learning these languages and I'm sure my lack of knowledge is the reason but for some reason I can't get ahead with my project. It looks like the learning curve is much steeper than it should be.

Anyways, here's my code for testing this functionality. The main application file looks like this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()">
<mx:Script>
[code]....
This works OK except the function returns false before the HTTP call returns its result. If I un-comment the while loop the onStatus function will never be called and therefore end up with an infinite loop. Not sure why this happens.

I have multiple items in my app that I would like the user to click on.Some items are completely different classes.The classes dispatch events and then when the events are captured, some modifications are done to the transform properties of a loosely coupled display object.I want two separate classes to dispatch the same type of event, since I already have an image class that draws images based on a given url... I want the classes to dispatch the events, but then I think I want the difference to be detected when the event comes along... i.e., I would like to recognize the 'origin' or 'sub-type' of the event. Some sort of if/then logic would suffice.

I'm designing an interface for a class, and the buttons that I am using all have multiple functions.For example, when the story button is clicked, I need the mc to stop playing and change to text (in the same window/screen, just no mc playing). The mc is 31 frames long, but if there's a way to just make it loop continuously until told not to, Currently, my code looks like this:
stop();
story_btn.addEventListener(MouseEvent.CLICK,story);
function story(event:MouseEvent):void { gotoAndStop(32);}credits_btn.addEventListener(MouseEvent.CLICK,credits);[code]...
When I click the button, the mc does not stop playing and the text does not show up.
