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 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 created an image uploader for an app I am working on. I first used php for the server side script, and everything worked fine. I found out afterwards I had to use .net, so I created new serverside scripts. The problem I am having is that my event.COMPLETE listener is never firing. I can receive data back using a DATAEVENT listener, but then it stops at this error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.
Here is how I am sending my file.
var fileRefReq:URLRequest = new URLRequest(FILE_UPLOAD_TEMP);
var fileReqVars:URLVariables = new URLVariables();
fileReqVars.subdir = "Temp";
fileRefReq.data = fileReqVars;
fileRefReq.method = URLRequestMethod.POST;
fileRef.upload(fileRefReq);
The file definitely gets uploaded to the first TEMP directory, but then it breaks with the above error.
Does adobe flex supports sychronous web service calls justify your answer???
View 1 RepliesWeb service calls are asynchronous in flex, but I wanted to wrap a web service call in a class to provide synchronous encapsulation. Something like the below - the user could call getMyMethodResult and get the result returned by the web service. I expected the thread that recieved the soap response would populate the variable _result and mean that getMyMethod would, after a time, find _result is not longer null. But it doesn't! Can anyone explain why this does not work?[code]
View 1 RepliesI 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?
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 building Flex 3 application and I have a geocoding service (http://.../GeocodeServer) on a ArcGIS server (ESRI). I'm trying to execute a query on this service in order to retrieve some informations.
Unfortunately, when I execute the query, I get this error : [RPC Fault faultString="" faultCode="400" faultDetail="Invalid URL"]
It's definitely not the URL that is invalid since my locator uses it without any problem.
I have a flex app hosted on a windows server running IIS. That same server has some rest services that the app interacts with. The rest services have windows authentication so that their urls cannot be called without credentials. The flex app needs to be accessible to the public so its files are accessed by enabling anonymous access. The problem is of course that when the app tries to call the rest services the browser pops a dialog box asking for windows username and pass. I naively hoped that if I set the anonymous access on the flex site to use the credentials of a windows account that had permission to view the rest services that would resolve the matter. I hoped that IIS would see the browser used the proper creds to view the flex app and use those same creds to get the rest services. Wrong, that didn't work.
So is what I want impossible? I'd like to find a way to not force the user to enter windows creds, keep the rest services using windows authentication, and have the flex app able to access the rest urls. Any ideas? Am I missing something? Also, it may turn out that the flex app is running on http and the rest services must be called with https. Does that change your answer?
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 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]);

There is some way to make a tweet from an AS3 app, passing a message and a url to tweet, and executing a callback if the tweet was succesfully posted?
View 1 RepliesHas anyone used or is aware of a service browser to test AMF calls?I am looking for a tool similar to ZamfBrowser ( http:[url].... ), but one that works for the Java environment.ZamfBrowser is geared towards AMFPHP.The idea here is to provide a service browser, that allows developers to test Java services using the AMF protocol, without having to go through the Flex UI all the time. There has got to be something out there already for this, but I can't seem to locate anything..... It's kind of funny and strange that a service browser exists for AMFPHP but not for regular AMF calls in a Java environment.
I would imagine something exists under Blaze or LCDS? ...Trying to find it in the docs but can't seem to find anything ....The best alternative I can think of at the moment is to use FlexMonkey to record stuff, and then to simulate it using that....which is okay I guess but still sucks because you have to go in and create the Flex UI first, whereas with something like ZamfBrowser, you simply point it at the service calls,it tells the server-side developers if their code works, etc. generates the required as3 classes for you... and makes the integration process much easier in a large team.
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?
Using the web services panel, I've connected to a web service, but all the method calls will only show the param structures/types - not the result structures/types. To the best of my knowledge, I'm sending the right parameters, in the right structure, but always I get an empty response.The web services panel:
Debugger results (with breakpoint placed just after a response is received):
Where might the problem be?
How do I execute callback functions dynamically by passing a function in as an argument to another function?
Look at this example:
Code:
package {
public class myClass extends MovieClip {
public function myClass(callback) {

I am experiencing a strange problem when I want to bind a service to a button or something else:
[Code]...
I can add the services to the Data Services panel but I have two strange things:
1) when I want to configure the return type he doesn't let me create a new ValueObject type, I only get the bottom datagrid which states: Properties returned by the operation: Property: country_Id, provence_Id, city_Id, id_cdpc, district_Id with the related values on the right side. Why can't I create a new data type on the top?
2) When I accept this and want to add the service call to a button (drag&drop) I get the following error: Error occurred while generating code. Make sure that there are no compiler eroors and try again after reopening the file. Componentn type services.cdpc.CDPC not found... (ps: When I perform a Test Operation everything seems to be ok, I get the expected output values)

View 1 RepliesI have created a client with Flex Builder which works in a browser but also in an Air windowed application. I must connect it to a server and it has to do asynchronous request related to changing data of the server.Because of the too much expensive cost of LiveCycleDS license, I was looking for other ways, maybe open source and i found the following solutions:

I want to download a file in flex. Here is my desired flow User clicks "view" Code goes to backend and get the file as an array of bytes bytes sent from java to flex via a callback flex then opens dialog and user decides where to save the file Unfortunately the last part is not on a user event but on the callback from the server. When I call new FileReference().save(...) it tells me this. An alternative could be
User clicks "view" Flex shows user the dialog and user chooses where to save file Flex goes to backend requesting bytes of file bytes sent to flex and data is saved. For this approach I am unsure how I can make the save asynchronous from the dialog. I want the user to save a file but the data but come from an array of bytes from the backend

I am pretty new to flex, so forgive me if this is an obvious question.Is there a way to open the Security.showSettings (flash.system.Security) with a callback? or at least to detect if it is currently open or not? My flex application is used for streaming audio, and is normally controlled by javascript, so I keep it hidden for normal use (via absolute positioning it off the page).
When I need microphone access I need to make the flash settings dialog visible, which works fine, I move it into view and open the dialog. When the user closes it, I need to move it back off the screen so they don't see an empty flex app sitting there after they change their settings.

In our app, I am periodically noticing that a particular event handler is not firing. 99% of the time, it works fine, but, every so often, it just dies. How can I find out whats happening? Is the DispatchEvent() not happening/working somehow? Is my listener still listening? Did something else catch the event, and not pass it along so that the 'right' listener can get to it ?
Here's a little bit of the code...
Thats a somewhat pruned down version of what the real code is, but I don't think I trimmed out anything important. The key, as I see it is that we fire up the params dialog, then start to listen for the closed event. Then, we show the param dialogs close function. What happens when it fails is that the trace message "caught close event.." is never generated, and, consequently, the closeHandler is not getting called at all.

I have a component called a TableDataViewer that contains the following pieces of data and their associated set functions:[code]This component is nested in another component as follows:[code]Looking at the trace in the logs, the call to set table is coming before the call to set dataSetLoader. Which is a real shame because set table() needs dataSetLoader to already be set in order to call its load() function.So my question is, is there a way to enforce an order on the calls to the set functions when declaring a component?
