AS3 :: Debugging - Debug Only Project In Flex - Can't Use Trace Or Check Variables?
Aug 7, 2010
I am trying to build a AS3 only project in Flex....I have tried debug mode, but seems like it takes so long to compile....I can't use trace or check variables...Are there anyway to do debug??
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.
I am running on Windows XP and recently updated Flash Player from v9 to v10.1. And Now, in the Debug Console under Flex Builder, I am getting a lot of debug statements(I think that is assembly). Below is an example, of what I get:
I am debugging both a flash cs4 project and a flash builder project, actually the flash builder project will load the flash cs4 project thru swfloader, but the system can only support one debugger at a time. So I am seeking a method to debug it simultaneously...
when I debug a flex application in the properties of display objects i also see variables that start with a dollar sign, like: $alpha, $width, $x, etc.. what are they? are they different from the "normal" alpha, width, x properties?
When I set a breakpoint and debug my application, Flash Builder 4 is not displaying static variables within the variables window. I'm using flash builder 4 to execute flex unit tests on one of my AS3 classes. I set a static variable within the [Before] function, which is accessed in each of the tests. I've set a breakpoint within one of the tests to see why it is failing, but I notice that static variables don't appear when I expand the 'this' object within the variables window. (In this case my static variable is the only variable associated with the class, so the only object in the variables window is the "this" object). How to make static variables appear in the variables window?
Is there a statement in AS3 that will return current class and/or scope? I'd like to use that in trace statements so that I know the exact location of a trace.
In my flex 3.5 project, I have a class (MyItem) extending Canvas. In this I have declared a private variable named itemInfo which is type of ItemInfo (which is another subclass of Canvas).
I wrote code to hide/show the iteminfo when the mouse is over/out of MyItem. I am not getting any error but it is not showing the itemInfo as expected, when debugged the code, surprisingly the variables tab in debug window does not have the variable itemInfo at all.
I have declared a dummy:int variable and it is also not visible.
This has never happened before. One of my .fla's suddenly won't trace at all. Anywhere I put a trace statement, it does not work. On the main timeline, in an MC, in a function... nothing!
Is there an option that I could have accidentally turned off or on?
A client is running into some problems with an application, and cannot install the debug flash player, meaning debugging is very hard. Does anyone know of a way to display the system's trace messages in a textfield on the stage for example? This way I could find the error by having it trace to their screen. I suppose a workaround would be to try/catch all over the application but that is not ideal and very cumbersome.
I'm just moving up from AS2 to AS3, using CS3. I'm finding out most of the stuff I need to debug with, but I can't seem to see the variables in the variable window.
I've looked through the documentation, and tried touching all the buttons they say to touch and setting the publish settings to allow debugging. Nothing seems to be working.
And, unlike AS2, the program seems to start all by itself, it doesn't wait till I click on the arrow to begin, and I can't get the step into and step through buttons to not be greyed out.
I found what I am looking for when I list all variables. I want to cut out the rest of the menus that create a fan of pages.I removed the SWF's from showing up. But I am still having issues with changing the nMenus = "14" which is the number of menus to show. I want to change the "14" to "9" so there are no spacing in between my 3D Pages.
I'm building a networked client app with Flash Builder, and would like to be able to set environmental variables or #define's such as server's hostname and port. For debugging purposes I want to connect the client with different servers (and for other devs too). In C/C++ I'd define TEST_PORT=8888 or something in the IDE or build environment, that way I wouldn't need to commit a settings file along with the client. But not sure what's the standard for Flash Builder.
I am getting Warning: 'flash' has no property 'prototype' every time I load a swf in my flashlog.txt.Does anyone know how to disable that warning or all warnings in the mm.cfg file or maybe some other way?
pictures2.php is working cos I just check so by rite the variables loaded should change.. but somehow each time I check those variables in myPictures.onLoad, the variables are always the same.
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.
With parent artifactId of swf, swc, war set to swf, swc, test respectively.On executing mvn on test folder(for that matter clean or anything) I get this following error.
G:Projects est>mvn -e + Error stacktraces are turned on. [INFO] Scanning for projects... Downloading: http://repo1.maven.org/maven2/com/test/swc/1.0-snapshot/swc-1.0-snapshot.pom
[code]....
Looks like its trying to download the project from maven's central repository instead of building it.
I know that flash use the garbage collection metod to delete variables from memory, however into the official guide I see: When you no longer need an event listener, remove it by calling EventDispatcher.removeEventListener(); otherwise, memory problems might result. Objects with registered event listeners are not automatically removed from memory because the garbage collector does not remove objects that still have references. So, it's exist a method to trace the memory status and know if a variable was correctly deleted?
I've recently bough Flex Builder 3 and I am completely dissatisfied with its reluctance to debug. It manages to debug a few times, but after that, it just doesn't want to "connect to the debugger".
When I first downloaded Flash CS3 Professional, I was able to enter an exceedingly useful debug mode by compiling using ctrl+shift+enter instead of ctrl+enter. I could toggle break points, step in, step over and view values stored in variables at a whim.
I must have accidentally toggled some option somewhere, because this interface no longer shows up. Instead, the only extra interface I get is the output menu with the following text "Attemping to launch and connect to Player using URL <file path> [SWF] <file path> - 71984 bytes after decompression" and while the swf does halt if the as3 code reaches a break point, it doesn't tell me which break point nor give me any options to progress the flow (not even through the pull down menu I have to utilize in order to end the so called debug session).
