[flexcoders] Using URLLoader, can't determine redirected-to URL in Event.COMPLETE
[Since my last post (http://tech.groups.yahoo.com/group/flexcoders/message/130012) got hijacked, started a small re-post. Sorry if this morally offends anyone.] Is there any way to find the destination of a redirect in ActionScript? For example, using Loader, you can access loaderInfo.url and it will give you the final destination that your original request got redirected to. But with URLLoader, I don't see any way to get the final URL in Event.COMPLETE. Am I missing something? Thanks in advance, Rob
[flexcoders] Determining the destination of a URL redirect with URLLoader or something else?
Is there a way to determine what the final redirection of a URLLoader resource is? For example, with Loader I can load http://www.youtube.com/v/6JBAxkZun3s, which gets redirected to http://www.youtube.com/swf/l.swf?swf=http%3A//s.ytimg.com/yt/swf/cps-vfl62967.swfvideo_id=6JBAxkZun3srel=1showsearch=1eurl=iurl=http%3A//i3.ytimg.com/vi/6JBAxkZun3s/hqdefault.jpgsk=UEhR45OlNzNS4sbCkLAX9_mTQARuHThZCuse_get_video_info=1load_modules=1 and then in Event.COMPLETE handler I can access event.target.url to get the destination URL of that redirect. But I don't want to load the YouTube AS2 SWF into my app, just get the redirected URL. So I was imagining I could do the same with URLLoader but there is no url property. I tried Sockets but that would require a policy file on YouTube's site. This seems like a simple thing to do, but why is it so darn hard? Or is there some flag in Loader to make it not actually load the SWF into memory? (I think it's conflicting with other components and causing some nice FF crashing.) Thanks, -R
[flexcoders] Re: Attaching custom data to events (while avoiding race condition)
Thanks you guys. The AsyncToken is what I was looking for *except* I
need this for non-HTTPService loaders so unfortunately it doesn't work
for me. I may have to try to roll my own similar solution.
Furthermore, I can't chain the calls.
I've considered extending the event classes, but then I'd have to
extend the loader classes and override the load method too so I can
pass this custom data along. That seems far too crufty for me.
Thanks again for the help anyways,

As you have shown it, you cannot rely on the value of the flag.
Instead, use AsyncToken to keep calls sync'd with results.
Hmm, I think AsyncToken is available on UrlLoader. If not, use
HTTPService.
function load(flag:uint) {
var asToken:AsyncToken = loader.loadSomeStuff();
asToken.flag = flag;
}
function handleComplete(event:Event) {
var asToken:AsyncToken = event.token;
var sFlag:String = asToken.flag;
switch (sFlag) {
case1:

So when I say thread maybe I'm using the wrong terminology. I'm not
actually talking about two different users/browsers. I'm talking about
the same browser running two calls of load().
Let me expand:
function onInitialize() {
loader.addEventListener(handleComplete);
load(1); // Say this takes 20 seconds to complete load
load(2); // But this one only takes 5 seconds to complete
}
private var storedFlag:uint = 0;
function load(flag:uint) {
storedFlag = flag;
loader.loadSomeStuff();
}
function handleComplete(event:Event) {
// What is storedFlag here?
}
The execution goes like this:
load(1);
load(2);
handleComplete(event1); // Triggered from the load(1) which is the
race since this storedFlag == 2, but this is handling the completion
of the first load. I really want to get that flag data from the event
object so there is no race condition.
handleComplete(event2);
This is a simplified example, but I really do have a use case for
this. Did I do a better job of explaining this time?

[flexcoders] Re: Flex Builder 3 debug builds broken, breakpoints all wrong
I agree and have seen this a few times. One odd occurrence is with a Flex Module in my Flex Application. It would serve up a stale build of the module unless I added a trace(foo); in the code, and then it would force a recompile. But when I would SVN revert back to the version without the trace statement, Flex would serve up the stale module SWF.

[flexcoders] Re: Loading ResourceModule and CSS with one HTTP call
Thanks Alex. I had pondered this custom Module solution as we're using
Modules for another part of our application, but it does sound a bit
hairy. I'll probably stick with programmatically setting the few
styles we need for now.
Cheers,

The Resource and Styles subsystems use Modules to load at runtime, and
Modules sort of imply a single main class.
In the end, the single main class registers various resources and styles
with the appropriate manager, so if you create your own main class and
copy enough code, you can pack all of the styles and resources into a
single module and have it register the right things with the right
managers. You probably can't use the compiler to generate the single
SWF so you may have to use the generated code and create a custom SWF.
It won't tax your brain, but will be tedious. I'd say it would have a
difficulty rating of 7 out of 10.

Subject: [flexcoders] Loading ResourceModule and CSS with one HTTP call
When loading a ResourceModule for the Japanese language, we also want to
apply a set of styles to change the default font to something Japanese.
I have a solution now that loads a ja_JP_Styles.swf through StyleManager
as well as loading a ja_JP_ResourceModule.swf with ResourceManager but
would like to combine the calls.
1. I know I could forget about loading external style SWFs and put
something like
StyleManager.getStyleDeclaration(global).setStyle(fontFamily,
resourceManager.getString(FooBar, globalFont));
after setting localeChain, but I'm thinking we'll want to change other
styles and would like to keep a generic solution like I have now, but
cut down on the extra HTTP request. Maybe this is my only option?
2. I thought one could somehow Embed(style.css) in my Foo.properties
ResourceBundle but it doesn't seem like that is the right path.
3. Also, I read in the proposed spec
(http://opensource.adobe.com/wiki/display/flexsdk/Runtime+Localization+S
pecification#RuntimeLocalizationSpecification-Problem:AstylevalueinaCSSs
electorcan
http://opensource.adobe.com/wiki/display/flexsdk/Runtime+Localization+S
pecification#RuntimeLocalizationSpecification-Problem:AstylevalueinaCSSs
electorcan 'tcomefromaresource.)
that one might be able to do something like the following, but it barfs
so this feature probably didn't make it in.
global {
fontFamily: Resource(bundle=FooBar, key=globalFont);
}
What is the best way to do this, am I stuck with option #1 if I want to
just do one HTTP call when switching locales?
Thanks,

[flexcoders] How do I trigger updateDisplayList() on *every* component in my Application?
I have an application with a bunch of nested containers and
components. We are internationalizing this app (with ResourceModules)
and when someone switches languages we need invalidateDisplayList()
called on every child component of the app.
Iterating through the Application's rawChildren doesn't return any
components that are nested in a Canvas for example. Do I really have
to do some recusive deal to traverse the whole tree to make the whole
app redraw? There has to be an easier way to do this that I'm overlooking.
Example: rawChildren only returns the Canvas, do I need to check if
it's a container and recurse?
App
Canvas
Box title={resourceManger.getString('boxTitle')}/
/Canvas
/App
Thanks in advance!

Thanks for the reply Richard. The problem I'm facing is that not *all*

Your email made me realize now that the it's my custom component
MyPanel (which extends Box and adds a bold label on top) that isn't
updating until updateDisplayList() is called. This was a deficiency in
how this component was written as Flex Text and Label controls update
fine. I wasn't accounting for these custom properties to be
programatically set since they were just hardcoded before i18n.
I changed
public var title:String;
to
protected var _title:String;
public function get title():String
{
return _title;

public function set title(value:String):void

_title = value;
invalidateDisplayList();

How do I do it? service = new HTTPService(); service.contentType = text/xml; service.resultFormat = e4x; service.useProxy = false; service.method = POST; service.addEventListener(ResultEvent.RESULT, onRestCallResult); service.addEventListener(FaultEvent.FAULT, onRestCallFault); service.url = https://privatesslcerthost.com/; + path; service.send(params);
