I have a system where clients connect via http streaming channels and use Producer and Consumer classes to dispatch and receive messages. I need to test the latency of messages in a way that adequately simulates real-world usage when the server is under load. I have 3 ideas for how this may be accomplished. Has anyone tried and succeeded or failed with these methods?
View 1 RepliesI'm trying to test a custom Flex 4 skinnable component, using the FlexUnit UIImpersonator class. If I run my tests from a FlashBuilder Spark only project everything works fine. If I try to test from a project with the mx component set on the classpath I get a "getElementIndex not available in non Flex 4 projects" error.Can I unit test spark components in FlexUnits visual test environment while still having the mx component set on the classpath?
UIImpersonator delegates it's method calls to a "testEnvironment".The implementation used for this "testEnvironment" is decided by the VisualTest EnvironmentBuilder class and the FlexEnvironmentBuilder class. If the FlexEnvironmentBuilder class can find the "mx.core.Container" on the classpath it returns a MX environment, else a Spark environment. Only the spark environment has valid implementations for Flex 4 relevant method calls on the UIImpersonator - like the addElement method.
In FlexUnit 1 it is possible to access the name of the currently-running test using the TestCase.getName() method because all tests subclass TestCase. In FlexUnit 4, however, there's no base class for tests; the tests are identified by annotations. So, how can I replicate the getName() functionality in FlexUnit 4?

View 1 RepliesI'm trying to create a Flex based internet application with an EJB layer in the server. This layer provides the XML used by the flex application. It uses the Cairngorm architecture.Currently, on an error I call the handler function defined in all the command files. How can I centralize this?My idea is to create a XML file that contains all the error messages and the types of error message eg:- Warning, Error etc. In the error handler, I will call the error handling function and pass a unique id which in turn will display the error message defined in the xml config file. Do I need to load this XML file in the Model layer of the application itself and store them as say global variables?
View 3 RepliesI'm working on a flex 3 application which will initially support only one language (which is not English) but may need to support English and other languages later. So I'm using the standard localization technique, with resource bundles. Now, somewhere I use the validators like EmailValidator which have some error messages displayed, these are in english and come with the flex sdk. How do I localize those messages?
View 1 RepliesI am completely new to the whole FlashDevelop/Flash/etc toolchain, but wanted to do some experimenting. I installed FlashDevelop and Flex SDK on my laptop, and thinks worked out just fine, except for one thing: the compiler messages are localized! Messages like "gebruik van een niet-gedefinieerde eigenschap" (Dutch.. sort of) are limiting my productivity. I don't recognize them because they look nothing like what I'm used to in any other programming environment, as a proper sentence they make even less sense than English error messages, and I certainly can't google them properly. Now I've already seen there are a couple of xml files and java/mxmlc/fcsh/etc configs I can tweak, but nothing so far helped.

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
View 3 Repliesi'm looking for a possibility to log messages in my flex 4.5 Project. This should cover errormessages in remoteClasses, errorHandler or messages typing by hand. After reading a lot of webpages, the solution from parslay looks good. i want to switch to this framework anyway. the benefit is the possibility to configure the logging behavior at runtime. but i don't understand the documentation. perhaps because I'm brandnew in parsley. Also google has no fitting result.

I've configured Flash Debug player to log trace messages from my Flex application to the flashlog.txt file.I can see trace() messages from my own code, thats ok.
However, would also like to see also trace messages from Fle SDK. I use Flex SDK ver. 4.1, and, for example, I would like to have trace message trace("app initialize app"); which is placed in function initialize() in mx/core/Application.as file in the SDK.
What I need to do? Should I recompile SDK somehow or is there a compiler switch to enable this? I'm a beginner in Flex, so I'm sorry if this question sounds silly.
I have a Flex/BlazeDS webapp (pseudo content management system) with a Java backend running on 2 Weblogic 10.3 servers for load balancing and HA purposes.Basically, I'm using AMF polling to update my app such that when a user opens a document from the search results, the corresponding row will display a locked icon across all user displays that currently have that document on the screen.
The problem I have is that if a user connected to Server A opens up document X, the locked icon will only appear on the screens of other users connected to Server A. The displays of users connected to Server B will not be updated. Is there any established paradigm or best practice to ensure that the locked update will propagate across all servers?
how can I strip trace() messages from a flex and flash applications? I write flash and flex applications and i use a lot of trace messages for debugging, but when i product the actual swf i want it to be stripped from any trace messages.

View 2 RepliesIm trying to connect a Flash client to BlazeDS. There has been some success with this from others using the vanilla BlazeDS setup. However I'm using the new Spring BlazeDS Integration from springsource and running aground. The flash client actually seems to be working in that I can see the correct data in the body of the returned object, but for some reason unknown it fails casting as an IMessage. It fails in PollingChannel.as on this line with the subject line error
var messageList:Array = msg.body as Array;
for each (var message:IMessage in messageList) <--
On application load I register a whole bunch of classes like so
registerClassAlias( "flex.messaging.messages.RemotingMessage", RemotingMessage );
registerClassAlias("mx.messaging.messages.IMessage", IMessage);
etc..
my code is basically
var channelSet:mx.messaging.ChannelSet = new mx.messaging.ChannelSet();
var channel:mx.messaging.channels.AMFChannel = new AMFChannel("my-amf", "http://localhost:8400/SpringA/messagebroker/amf");
channelSet.addChannel(channel);

I need to calculate the latency means time difference between the two user machines the scenario is: 1. App 1 publishes stream 2. App 2 play the stream published by App 1 Now in App 2 I need to show the time difference between the App 2 and App 1 time. Say if current time on App 1 is 10:46:30 and on App 2 it is 10:50:20 then need to display the difference. How to send the time value to App 2 from App 1 as time zones for the two users may be different.
View 1 RepliesWhen synthesising sound using the SAMPLE_DATA event of the Sound class, the Flash documentation recommends writing out as many samples as possoible up to 8192. On my system the sound cuts out unless I write at least 4192 samples each event. That's a full tenth of a second, which is going to be user-noticeable.
I may have the option of buffering things up ahead of time, but this is a major annoyance for my application.Is there any way of getting lower latency audio output?
My buttons only work when I click on them on the stage while having the "enable simple buttons" option on. They do not work if I try to "test movie," "test scene" and publish it to a SWF. Nothing responds whenever I am in these modes. I am using Adobe Flash Professional CS5 Actionscript 2.0.

I am developing a simple fast-paced 2 dimensional real-time multiplayer game in Flash. Players can only shoot and walk in point to move fashion. I use TCP socket connection (AS3 doesnt offer UDP).All I want is to synchronize players' actions so Player1 could see the same on its screen as Player2,Player3... or just see close representation (position,taking damage,etc).
I know movement vector coordinates and I can easily interpolate on them using latency. However,I can not figure out an effective way to determine how much time (T1) did it take the state update to travel client1-server-client2 and then make corrections to client2's screen based on T1.(You know, ping times may fluctuate quite a bit).I need a way to do the above-mentioned, i need way which is as fast and as accurate as posssible but not extremely sophisticated. (what algorithm should i use?
Suppose there is a live WAV stream that can be reached at a certain URL, and we need to stream it with as little latency as possible. Using HTML5 <audio> for this task is a no-go, because browsers attempt to pre-buffer several seconds of the stream, and the latency goes up accordingly. That's the reason behind using Flash for this task. However, due to my inexperience with this technology, I only managed to get occasional clicks and white noise. What's wrong in the code below?
var soundBuffer: ByteArray = new ByteArray();
var soundStream: URLStream = new URLStream();
soundStream.addEventListener(ProgressEvent.PROGRESS, readSound);[code]....
I have a project that plays several sounds and triggering interaction on key presses. On mac everything is fine - the animation and the sound gets triggered simultaneously. However, when I port it to windows (either as a swf or exe projector), there seems to be a .5 second delay in the sound. I have to load the sound files from a local filesystem. I've tried pre-loading all the sound so I can just play the sound object when needed, but the latency is always there.
View 1 RepliesIn the game there is a backing groove played by triggering one movieclip to play. The user triggers short sounds from buttons embedded in drag and drop movie clips to play along with the backing groove.
On Safari or Firefox on mac the timing is absolutely fine.
On IE on Windos XP there is enough latency to make it unplayable.
I used to code with "Processing" so maybe I keep the same habbit when I code in AS3. I'm not really sure how to animate in a good way using Enterframe. I made a not so complex animation and I am suprised that there is a very bad latency when I run it. Maybe there is something I don't understand when I write Graphics.
At each Enterframe, I write a black rectangle with a 0.3 alpha to progressively erase old lines and just after I draw new lines.
Are these these Graphics lines and Graphics rectangles stay in memory? Do I have to delete it when they visually disapear from the stage?
Code:
package

I have two scenes in my flash file and in scene 1, first button takes you to frame 2 where movie clip is -works
on (release) {
gotoAndStop("scene1",2);
}
second button takes you to frame 3
but on scene 2 that performs same function as scene 1, the first button
on(press){
gotoAndStop("scene2",2);
}
instead of going to frame 2 goes to frame 3. and the second button goes correctly to frame 3.that happens when i test scene! when i test movie all buttons work properly.
Because of network latency,there will always be latency, how to know how many seconds the latency is with ActionScript?
