Flex :: RemoteObject Intermittently Failing To Invoke CFC
Jun 10, 2010
I have a Flex app that uses Flash Remoting and the RemoteObject to pull data from a ColdFusion CFC. About 75% of the time it works, but the other times I get a message using Charles (a debugging tool) that says faultString = "Unable to Invoke CFC". FaultCode = "Server.Processing".
im trying to output my database information in a text input field in flex by using remoteObject(cfc). The information is being provided by a database using a query and an array collection. I'm just unsure how i go about taking the queried array collection information and display it into TextInput Fields.
I have a remoteobject within my main.mxml.I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint.When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence.[code]
I have an application built on Flex 2. I am writing a new application (module based) in Flex 3. Will these be able to co-exist? Can I invoke Flex 3 module from Flex 2 application?
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've been tinkering around with Flex RemoteObjects, and I've found that they aren't very well behaved with respect to timing out.First, I can't figure out how to set a timeout on "connect". I know I can set requstTimeout, which will correctly timeout after an initial handshake... But if the server doesn't handshake, the connection doesn't time out (eg, the server accepts the connection, then does nothing with it, the client will just be left hanging).
Second, when a requestTimeout fires (timing out the request), Flex doesn't actually take any steps to tear down the connection - it just leaves it hanging there (no RST or the like). Clearly, this is more than a little bit undesirable. Is there any way to explicitly tear down the connection after the timeout?
I was wondering what is considered to be a best practice when I have multiple components and use RemoteObject for AMF communication with a PHP backend.
Have the RemoteObject in the Main.mxml file with all the methods declared here (with handlers and all) and have all components call functions from the parentApplication, thus having a centralized result and fault handling, but making reusiability more difficult.Have a RemoteObject in each component with only the methods (and handlers) relevant to that component, thus making it easy to have clean, reusable components.
Is it possible to abort a flex remoteObject call? I tried the below method but the http request is still loading in the background:[code]The thing I'm interested in is freeing up the browsers HTTP Pipeline, just like in javascript where you can use abort on the XHR.
I need to make a function that execute a java method and return his result. It is static becouse a lot of other functions will call this function. So I did this:
public static function FKDescription(dest:String):String{ var jRemote:RemoteObject = new RemoteObject(); var s:String;
[Code].....
But the function returns null, because the valresult() was not been called at the end of main function. What shoud I do to make FKDescription() return the string that came from remoteobject?
While this is similar to another post, that post (does not indicate how to perform this (if it can be done) without instantiating an object. Also, without success I have tried multiple variations on the theme of:
I have used Reflection in both C# and Java. BTW, the code that I am attempting to get to work in Flex is mirrored in both those languages and works as expected.
Non-functioning Flex Code: private function ipMethodTester( ipMethodName:String, shouldPass:Array, shouldFail:Array):void {
I am in the process of writing an application in Flex 3.3, using the Cairngorm framework, for deployment as an AIR application. The application heavily utilizes RemoteObject services to get data from a web server.Each of my service delegates extends a common class which provides a method for calling service methods on the RemoteObject.So, where I previously usedServiceLocator.getInstance().getRemoteObject('myService').myOperation.send();I instead usethis.send('myOperation', 'myService');I use this method instead of calling the RemoteObject operations directly because this method adds another, global, responder to the operation call. This extra responder analyses data in the headers of reponse from the server.
Or at least it should -- this is where the problem is. In the result data (event as mx.rpc.events.ResultEvent) the headers property is always null despite the headers definitely being sent from the server.
I have a swf which, for some reason, has four RemoteObjects pointing to the same ChannelId, but they are listing that channel as being at two different spots. In four of the five RemoteObjects, everything behaves as expected, but in the fourth (WidgetService), the version on dev is switching from dev.context.root toloc.context.root. To make matters more confusing, it only does this on the dev server (QA and production are fine, as are local builds).The relevant information from the config files follows:
#This is from build.properties, which is used by Ant #to build the swf on the server flex.sdk.dir = /path/to/sdk/flex_sdk_3.2.0.3958
I am using Google AppEngine, in conjunction with PyAMF to provide RemoteObject support. In my Flex code I make several RemoteObject method calls at once which tends to batch the AMF Messages into a single HTTP request. Most of the time this is fine but AppEngine applies some strict per request limits (in this case I am hitting a DeadlineExceededError - max 30 seconds). A number of service methods are expected to take upwards of 10 seconds and if these are batched by the RemoteObject into 1 HTTP you see where this is going. Now you could say refactor your service calls and that is also going on but not really the question being asked here. Is there a way to prevent Flex RemoteObject from batching AMF requests for situations like this? I have done a fair amount of Googling on the subject and come up with bupkis. It seems to me that I would need to implement a custom version of mx.messaging.channels.AMFChannel or something of that nature, which seems waay too hardcore for a feature like this
I am having some issues trying to make an AIR application connect to a RemoteObject when the application is run in a domain that has proxy servers for outbound connection.The error provided is as below:
I'm trying to connect to AMFPHP over SSL (self-signed) from a Flex 4.5 application.Will this work? Or do I need an authority-signed certificate?Will it silently fail or prompt user like it does in browser?How do I need to edit the services-config.xml file for this to work?
I am trying to create and build a flex library project (.swc) using maven 2 firsttime.I am able to create directory structure but build is failing. My maven settings are : Maven version : apache-maven-3.0.2
I have created an API in AS3 that uses Flex bindings. The API is being used by two other developers. I am delivering the API in an SWC that includes all code, including the required Flex libraries. The two other developers are building the API into AS3-only projects. One developer is compiling using the Flex SDK through FDT. He includes the SWC in his project and he is able to bind any bindable property. When he uses ChangeWatcher.canWatch on a bindable property, it returns true.
The second developer is compiling using the Flash CS5 IDE. He includes the SWC in his project using the Actionscript settings window (merged into code). But none of the bindings, including ones internal to the API, are working. When he uses ChangeWatcher.canWatch on a bindable property, it returns false. What could the Flash IDE be stripping out that causes ChangeWatcher to stop functioning? What is ChangeWatcher.canWatch actually checking? Is it the metadata, and if so, how can the metadata be preserved in the Flash IDE?

I am working on a project using flex/java/blazeds. This worked fine on local host however now that i have uploaded to a tomcat server(online), after having an error with the service uri, this error has now seemingly been solved, yet I am receiving another error which is as follows:
I have a couple of remote object methods that I want to respond to in different ways depending on the context, but I'd rather not set up a bunch of different RemoteObject aliases.Some background: Let's say I have an admin application that displays sales stats in different ways. The remote method looks like:
<mx:RemoteObject id="rpt" destination="AMFServer"> <mx:method name="getSalesStats" fault="getSalesStatsFault(event)" result = "getSalesStatsSuccess(event)" />[code]........
The getSalesStats method takes an employee ID and a sales type as its arguments. You'd call it like:
rpt.getSalesStats(120, "peanuts"); public function getSalesStatsSuccess(e:ResultEvent):void { salesdata:ArrayCollection = e.result.rows as ArrayCollection;[code]......
I'd like to pass something through the remote method to the responding function, like:
If I send remote data from Zend_Amf to Flex, if two array properties on the object have the same data values they are deserialized at the remote end with the same memory storage.Example: AS3 object:
Snippet: [RemoteClass(alias="TestVO")] public class TestVO
I'm calling ColdFusion cfc method using RemoteObject method of the Flex.
[Code].....
So you can see that I changed the sequence of the parameter, when I call the cfc method. But it does not worked. It means that <s:arguments> does not pass the named parameter. Is there any solution for that? As you can see that I may have some of the arguments not mandatory so, it must be passed by name.
When i run it in Flash Builder (debug mode) the remote object called successfully. but whenever i build the application (AIR application), then the remote object will return no result nor fault, the busy cursor is showing about 3 seconds. then no clue at all. how to get advance fault or something than regular fault event or result event? or anyone have the same experience?
UPDATE: Actually it was failed only for ONE service method, for other method (some of them took longer time to call) the service call is work fine. CASE SOLVED So the problem was not on the service call, but on my result conversion that cause the advanced datagrid failed to render.
I am using RemoteObjects to call ZendAMF PHP from Flex/Flash Builder 4.6. I want to stop or abort a method call before it sends the request to the server based on an event or similar.
I have a class where I create and store all the RemoteObjects - for example:
activityLogService = new RemoteObject("zend"); activityLogService.endpoint=endpointServer; activityLogService.addEventListener(FaultEvent.FAULT,faultHandler);
Then later I can simply call this object:
remotingService.activityLogService .getRecords();
I am trying to find a way in my remotingService object to stop the request - and not send anything to the server - for example if some variables are not set properly.
I noticed there is an invoke event: activityLogService.addEventListener(InvokeEvent.INVOKE,invokeHandler);
However, I can not tell if that's going to stop things at the proper point, or if it's even possible to actually STOP the request - if so, how?
How can I find the return value of a executable which has been invoked by a AIR app using the NativeProcess API? I am using Flash Builder 4. The following c++ generated executable
festival --tts "HelloSpeak.txt"
works fine on the Windows cmd line , but on invoking by the NativeProcess API like in the example article doesn't produce the desired result. I invoke the command with the arguments on a button click handler, but there is no TTS generated output.
