Web 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]
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:
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 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?
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?
I have a several Grails services that are invoked from Flex code using Spring BlazeDS integration. I wanted to add some general debug logging using the groovy metaClass. I have the following in a bootstrap class:
Has 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.
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):
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)
In the code below when I call chkAuthentication function from another function the remoteObj.login (login function in my service file (.php)) is called after the remaining code in that function. i.e., the loginStatus is returned from the function before the result-handler function loginResult is called. but my loginStatus is supposed to be set in loginResult function. It seems that the asynchronous behaviour is the culprit. what should I do in order to get the loginResult function to complete first?
I'm using flex4 and actionscript, and need to treat an event in a synchronous mode. Is it possible that? More exactly, i want to execute some queries in a database, and need to be synchronously.
I have small Flex web based util with single button. On this button click a request is sent to server and the response must be read in the same call.This is important not to wait for response with event handler (which is trivial).Basically this is synchronous call.I am ok with blocking ui and so on.
e4x programming extension is native to Actionscript and makes sense to use it over Xpath or any other DOM interfaces. I would like to know from flex community if they had any bad experiences like performance, etc, or any other gotchas.
I just read a good tutorial at [URL] about creating simple apps with AIR/FLEX. What are some similar pages and/or good books that I can read to move from "beginner" to "novice"?
What coding tools do you use for improving effectivness of programming in FLEX?I found Tr.ace() AS3 Debugging Utility whichme a lot with working in a team of programmersframeworks like RobotLegs and others.
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?
I created a screen(calculator) with bunch of buttons,i can handle button event with one handler.But i want to know that can we do a one handler for all buttons......likein java we can perform the task of perticular button by like this
How can i settings crossdomain.xml my flex project.* this is my crossdomain.xml.

I've tried lots of different methods but my project send error message "Security error accessing url Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL [URL]"
I am trying to access a .Net service which requires an authentication header. If WebService is used it works fine. But when it is accessed using HTTPService it throws error. The project is already done by somebody else using HTTPService. Now changing to webService requires some time since there needs to be modification in a lot of files.
Below is the SOAP envelop required by the service.
I am using Flex and with the AS3 libraries.I can make calls etc but when i get values returned in the event,they are in RawResult. I am not sure how to turn that into an arraycollection etc so i can make use of it in flex, or if there is a better way of accessing the data, generally speaking.
var friendsDoc : XMLDocument = new XMLDocument(e.data.rawResult); var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(true);[code]....
I have to use flex 4 for the front end and php with Symfony 2 as backend. I want to use amf to call remote methods on the php. I have known that Symfony 2 does not have plugin for amf communications with Flex. In this case how can I connect them? or I have to use httpservice/webservices which is slow in performance.
Is there some sort of configuration settings in FlashBuilder 4.5 where you can easily switch between webservice urls? Right now I have to delete and recreate the web service every time I switch from local to production and vice versa.
I have the following application in flex. I want to call two different remote objects in parallel.
[Code]...
Now what the methods do is to print sth. when they are called, then wait 8 secs and print sth. after that. When clicking each button seperatly, it works, both methods are started in parallel. However, calling both method the same time, leaves one service to wait with its call while until the other is executing. How can I avoid that?
I have a Flex 3 application that makes a call to a webservice. That webservice calls returns a 2 Mb file that flex reads and parses. The problem is that it takes sometimes 45 seconds. I was wondering if there is a way to cache the response form the webservice? So the next time I load the flash movie it doesn't have to re-download the full file but just the updated data.
We are converting a Flex application to use some REST APIs.
When adding the mx.rpc.http.HTTPService class to the code, the SWF binary output grew from 175KB to 260KB. This is an unacceptable hit.
Is there any better way to do lightweight REST calls from a Flex app? Are we better off using an external interface JS just to make the calls from there?
