Flex :: Debugging Event Flow?
Jul 6, 2011
I'm stepping through my code to figure out why a certain function takes more time to run the first time it gets called than on successive calls. The code flow for each function call is the same up to when a dispatchEvent gets called. I'm pretty sure it's different afterwards, as that call takes a lot more time the first time around. Unfortunately, I have no idea which other parts of the code chew on this specific event and thus cannot step through the handling of such event.
The question: is there a way to either figure out who handles such events or magically step through the handling code without explicitly setting breakpoints there?

I have a custom TitleWindow component that is registered to listen for keyboard events from the user (so that esc closes the window, enter saves, etc.). However, in my testing I've found a couple cases where my keyboard event handlers don't fire. My best guess as to why this is happening is that there is some child component somewhere that has stolen focus and is stopping the keyboard events from propagating.
Unfortunately, due to the large number of components in my TitleWindow, I have no good way of knowing who has stolen the focus. My question then is, are there any good tips / techniques / tools for debugging focus issues and event propagation in Flex? Basically, I need something that will tell me who has the focus at any given time and who's handling an event at any given time... is that possible?

There's a lot of talk of how the new Event Flow makes for easier communication between classes.This sounds swell,but nowhere is it properly explained. Every example I find concerns dispatching events within the same class or looped through a customEvent, but I need a way to tap into this Event Flow for backward communication.I have a mainGUI document class that distributes my application subclasses.How do I set up a listener within mainGUI that gathers certain events from any of its children or grand-children? And how can I use this line to post object properties?

My goal is to shoot a bullet everytime I click on ship. What happens, in fact, is that If I click on it once, the bullet is shot, but if I click on it twice before the first bullet is off the screen, the first bullet literally stops(it does not disappear, only stops) and the second bullet is shot.
public var ship:Ship = new Ship();
public var bullet:Bullet = new Bullet();
stage.addChild(ship);[code]...

What is the proper OOP method of communicating between classes that are not on the display list?
For example: The Document class instantiates a new class just for loading in different XML files. This XmlLoading class should let the document class know when the xml has been loaded and parsed so that the interface can be built out.
From my understanding, events can only be listened to and dispatched through the display list, but since there is nothing visual with this xml loader, it doesn't make sense to me to make this class extend a sprite and add it as a child of the document class.

I m building a little application, im design the graphic in Flash and im using Flash Builder for the Programming Side. I have 5 MovieClip inside a Sprite (the container), and i want to listen for MOUSE.CLICK. I add the event listener to the Sprite, instead of one for MovieClip, and its working good like this.
What if inside the Sprite (the container) i have also a TextField and exclude it from the event flow?

Is there a way to make event flow occur synchronously?
Basically this is my scenario. I have a single method call that gets triggered by a server request. I want to be able to notifiy subscribers that the method has/is executing so that they may return a result. By modifying an attribute of the actual event object, the method can return that result to the server dynamically. Eg:
Code:
//method invoked by server
public function whatever(...parameters):* {
var event:MyEvent = new MyEvent(MyEvent.TYPE);
[Code]....
This code works around 70% of the time, but sometimes I see things are really happening asynchronously in Flash Player's event flow. Is there anything I can do to regulate this and make sure it happens synchronously?

I am currently working on a Flash socket client for a pre-existing service/standard. The service uses TCP flow control to throttle itself and the Flash socket is reading in everything as fast as it can despite not being able to process it as fast as it's being taken in. This causes the bytesAvailable on the socket to keep increasing and the server never knows that the client has fallen behind.In short, is there any way to limit the size of bytesAvailable for a Flash Socket object or throttle it in some other way?

An existing (though incomplete) FLEX3 project was given to us to finish (always a nightmare).It is quite small but highly abstracted (contains well over 150 files to support only about 10 page views). I'm attempting to trace a single mouseclick event through this maze.
Is there a way to print out an actionscript trace and/or component flow using the debugger (or any other tool that anyone knows of)? The flash.txt file appears worthless since it doesn't contain ActionScript calls and/or component flows.

Is it possible to run a Flex client in IntelliJ internally and have it talk to a separately deployed server instance? The server's a java webapp. This will make developing, especially debugging, much easier. What I'm trying to avoid is having to rebuild and redeploy the webapp to get the updated Flex code in it. I want to just build flex and run it against the server.
The flex client is embedded in an HTML page on the server, so in production the users access the client by going to a web page. We're using GraniteDS if that's important.
Update
I'm managed to cobble something together, but it's ugly.I made a copy of our wrapper HTML page and fixed the links to refer to the SWF in target.I setup the IntelliJ run config to point to that HTML page.I set the 'Place SWF file in a local-trusted sandbox' to true
Hardcoded the {server.name}, {server.port}, and {context.root} values in the service-config.xml GraniteDS config file to localhost, etc.
I can mavenize #1, but #3's isn't really a permanent solution. That part is still a problem because I can't check this in.

Currently i am doing the following onCreationComplete = init();

I've hit a snag when trying to debug an AIR app using adl.
Although adl successfully launches, the application never appears on screen / starts up.
eg:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
[Code].....
Update: I've also since uninstalled and reinstalled Flash Builder (and therefore, the AIR SDK), and it still doesn't work. I think this adds weight to the port conflict, but still leaves me unsure of where / how to proceed
Further update Compiling exactly the same codebase to a AIR installer, installing, and running the application works fine. (Ie., a production release). However, the codebase fails to launch with adl. This pretty much confirms the issue as a local machine config problem somewhere with adl, and not an issue with the codebase.

I have flex application consisting of several modules which is configured using maven. I'm using flexmojos plugin to build the application. When I try to build the application using maven it builds successfully. But I need debugging features of Intellij Idea (i'm using 10.0 version). So at first step I run maven compile command to generate *-configs.xml to enable Intellij idea compile my application. At second step i run IDE's compile(or make) command and it says:

I have installed Flex Builder 3 and Flash Player 10 on my machine.
I don't know where the trace output goes because I just don't see it (I tried debug and output windows).
Also the breakpoints don't hit.

I am working with a project that is developed in the flash environment, but I love the flex/eclipse debugger in that i can throw a breakpoint in and inspect the vars that are present. Is there a way that I can debug flash in the flex environment?
I have (of course) googled the subject and found that there are several posts on the topic but they are incomplete, missing images, or not working in my environment.

I've noticed that when debugging using the eclipse flash builder plugin, one cannot drill in to the key set / values of a flash.utils.Dictionary in the Variables view. Even after selecting the "Show Logical Structure" button. Does anyone else run into this issue? Is there anyway I could see the see all of the keys / values when debugging (apart from writing a loop to do this or manually testing possible keys in the Expressions view)?

m working on an Adobe Flex application that loads lots of Flex Modules and other Flash sub-applications and Flash resources. Each time one successfully loads the flashlog.txt and Flex Console show a trace like "[SWF] filename.swf - [filesize] bytes after decompression". Specifically:[SWF] Main.swf - 1,361,299 bytes after decompression [SWF] core/Core.swf - 516,390 bytes after decompression
I don't want to disable traces because I am debugging, but these traces are rather noisy. How can I suppress only the [SWF] loaded traces?

I am trying to use Flex builder for the first time in years. I haven't used the "Run Application" option before, and when I do that now it tells me "Errors exist in required projects" and whether I should proceed. I would like to debug those errors. Does anyone know how I can do that? PS: When I click the "Debug" button, it does exactly the same thing. I don't see error output in the console views.

Is there any way to automatically deploy to a server after I build a flex app, and then debug using the remote url ?
This is totally possible in FlashBuilder, but I am highly hoping that it can be done in FD as well.

I tried to search, but couldn't find anything on the topic. In many languages in eclipse you can execute code in the middle of debug session. Usually it's done through the console.
Is there a way to do the same thing in the Flash Builder? EDIT: Ok, i'll to explain better. Is there a way to execute some code in the middle of the debug session? Like in python you can type in console in pydev(eclipse) when the program is paused(being debugged) and run any code you want.
