Flex :: Event.Complete Does Not Fire When Loading A URL?
Aug 11, 2010
I'm an experienced AS developer, but this is something very basic about flex that I can't figure out. In the class below, I'm not sure why the function imageLoaded would not be executed when the image loads a url. Is there a race condition happening here? The application is completely loaded by the time this object is created and setPicture is called. How can I get the Event.COMPLETE event to fire properly in this case?The line and Log.info functions are conveniences for me, and they definitely work. Here's my MXML definition:
<?xml version="1.0" encoding="utf-8"?>
<photo:PhotoClass xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:photo="com.xxx.widgets.photo.*">

set some filters on the bitmap after it has been loaded.During development (Debug mode), everything worked and the even has been fired just fine.But now I switched to Release mode and the complete event doesn't fire anymore.To load the image, I set the source property of the image to an URL that points to a PNG image. That does still work in release mode, so the image appears correctly.It's just that the "complete" event doesn't fire, no matter what I try.

I want to dynamically load several png images from 6K to 2,5M. I create the loaders in a for loop and start them all at the same time, and listen Progress, Complete, IOError and SecurityError on each loader. The problem is the COMPLETE events are not always fired, even if Progress events show all images are fully downloaded.
I tested with Firefox and Chrome, I load 4 images 2.5M, 2M, 1M, and 6K, then I just get 2 or 3 COMPLETE events, sometimes the 4 are fired with Chrome. Did not find any workaround. I tried to listen ProgressEvent and call the completeHandler when bytesLoaded == bytesTotal but the loaderInfo.content is null (and bytesAvailable =0) so I can't get the Bitmap.
1) Is there a known limitation in the number of simultaneous loaders, from flash player or browsers ? Does Adobe recommend to have queued loaders instead of simultaneous ?
2) Is there a way to get the loaded Bitmap when COMPLETE is not fired ?
3) I don't keep the loaders in a property of my class, and use weakReference for the listeners : the issue can come from my code ? (but the ProgressEvents are received until the download is complete)

I'm trying to load PNG images with ActionScript with a Loader object. This works fine for some of the images (the INIT and COMPLETE events are fired as expected), for some other it doesn't. I've read in this thread that a URLLoader might help, so I tried that, using the loadBytes() function afterwards. Still doesn't work: the URLLoader fires the COMPLETE event, but the LoaderInfo object does not.I've written a sample class that demonstrates the problem with two files (one working, the other one not).
public class LoaderTest extends MovieClip {
var output:TextField;
var loader:Loader;[code].....
All images were generated with the PHP GD library and I'm compiling with SWFTools's as3compile.The two images map_in_big.png and map_us_big.png are in the same folder (not allowed to post more hyperlinks).

I've got a file upload that's working just fine except for the fact that the Event.COMPLETE event seems to take way longer than it should to fire. The Progress event is firing just fine and filling up the progress bar, and on top of that the entire file arrives on the server just fine, and way before the complete event fires. I've read I need to echo something back from the server, but I have no idea what that should be.

I am loading in binary files with the url class which can be quite large 10mb + and it works fine on my server but another server I am testing on it can sometimes not work. Sometimes it will not load the file and other times it will only load about 20% and it throw a complete event??? Then of course other times it works fine. This server is https maybe that has something to do this it?

f.source="video1.flv";
var vidWidth=990;

this only happens when I'm running from my local web server. The external swf get loaded just fine and I get the progress event, but just not the complete event.
Here are the three events I listen for currently
myLoader.contentLoaderInfo.addEventListener(Event. COMPLETE, OnGameLoaded);
myLoader.contentLoaderInfo.addEventListener(Progre ssEvent.PROGRESS, OnGameLoadProgress);

I am looking for an event which is fired (if any) after a chart is rendered (visible in UI) in Flash, we are using Flex SDK 3.0. We have to capture the screenshot after the chart is rendered, current implementation adds a huge delay in update_complete event callback, this is slowing down the whole job of generating images. I tried to use EXIT_FRAME event, but this doesn't seem to serve the purpose.

I'm having trouble firing or capturing the results of an event firing.
Here's the current code...
<s:Panel id="instructionsPanel" left="0" right="0" top="0" bottom="0" title="Register">
<mx:HTML id="htmlViewer" left="10" right="10" top="0" bottom="10"
[Code].....
What's happening is that the user fills out a form in the HTML Viewer, then when they click the submit button I want to be notified of the page change.
If they land on URL A, then they'll be shown one message. If they land on URL B, they'll be shown another.
However, the event isn't firing.
I've also tried COMPLETE and HTML_DOM_INITIALIZE.

i'm trying to embed a swf to my as3 flex project like this:
[Embed(source = "../assets/next_button.swf")]
[Bindable]
protected var nextButtonClass:Class;
protected var next_btn:MovieClip = next_btn = new nextButtonClass() as MovieClip;
// ...
next_btn.addEventListener(MouseEvent.CLICK, onAdChange);
next_button.swf is as2 and created with adobe flash cs4. there is a single button inside it.
if i change type of button symbol to movieclip at next_button.fla, there is no problem at passing CLICK event.
i tried to cast next_btn to mx.controls.Button and fl.controls.Button classes, next_btn is becoming null in that case.
by the way button is reacting mouseover and click events properly just doesn't pass it to upper swf.
is there any trick i can do to pass Button events to my container swf?

I've got a canvas within which I have a list. The renderer for this list calls upon a "Text" field, with the "link" element of this field set to a function. The "htmlText" of the field is set dynamically to a mixture of words and links. Basically the function checks to see which tag within the htmlText has been clicked and performs an event accordingly.However, you have to click the link twice for anything to happen. Whilst debugging the code I noticed that the function referenced by the "link" element isn't actually even called until the 2nd click.
<mx:Text
id="textCanvas"
width="100%"
color="0x323232"
selectable="true"
link="{lbl_link(event)}" />
I've changed the code a little bit to make it easier to follow, but the ActionScript is roughly as follows:
private function creationComplete():void {
textCanvas.htmlText = "Hello <a href='event:username'>" + username + "</a>";
}

I have no experience with Object Oriented Programming, so I wonder about the following:

2) Can I nest several listeners as seeing in my code below?

Within my application I'm using a Scroller component. I can't seem to figure out which event I should set up a listener on in order to know when content is scrolled. I tried Event.CHANGE on Scroller.verticalScrollBar property but apparently that event doesn't fire when the user scrolls with a mouse wheel or arrow keys.

I created an image uploader for an app I am working on. I first used php for the server side script, and everything worked fine. I found out afterwards I had to use .net, so I created new serverside scripts. The problem I am having is that my event.COMPLETE listener is never firing. I can receive data back using a DATAEVENT listener, but then it stops at this error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.
Here is how I am sending my file.
var fileRefReq:URLRequest = new URLRequest(FILE_UPLOAD_TEMP);
var fileReqVars:URLVariables = new URLVariables();
fileReqVars.subdir = "Temp";
fileRefReq.data = fileReqVars;
fileRefReq.method = URLRequestMethod.POST;
fileRef.upload(fileRefReq);
The file definitely gets uploaded to the first TEMP directory, but then it breaks with the above error.

While trying to load a Bitmap onto a SWFLoader the Event.COMPLETE event is not being triggered
mySWFLoader.source = new Bitmap(Bitmap(someEvent.content).bitmapData);
but if I use a URL as source the complete event is triggered:
mySWFLoader.source = "http://example.com/123.jpg";
Is there some kind of restriction while using Bitmap as source?

I need to pass along a string with my FileReference, or provide that string as an argument when an event fires. To be clear, it really annoys me that AS3 doesn't allow you to pass parameters on events.Right now, I've extended the FileReference class to include an additional variable. I'm trying to get this to compile, but it won't compile; I think I don't know how to import this class correctly. If you can tell me how to import this class correctly so that I no longer get Error: Type was not found or was not a compile-time constant at compile time that would be great.
This is the extended FileReference class:
import flash.net.FileReference;
public class SxmFR extends FileReference {

enter code hereBeen really frustrating just trying to load a swf from a swfloader in Flex and then accessing it's content. I'm sure once I figure out how to do it once then it'll be fine, but I've gone thorugh a bunch of tutorials and somethings not right. Here's my flex code:and the as code:
public function initHeaderSwf():void
{
trace("INITIATIED");[code]........
Here's the problem: The swf loads, there is no problem there.i see it in my compiled swf. but the complete event doesn't fire. CreationComplete will fire, and then I try, after that, to make a event listener for loading the actual swf, that doesn't fire.I've tried it a variety of different ways with no luck.All I am trying to do is change a text field in the loaded swf.I imagine this might be a problem with the sequence of things loading or something like that, but not sure.

So, I'm trying to load resources, add them to a dictionary, and have a drawing method search through that dictionary and draw based on certain predicates. I have a function that iterates through an Vector of Strings, calling on an instance of Loader to load them instantiated as a URLRequest.
private function loadImages(urls:Vector.<String>):void
{
var loader:Loader = new Loader();
[Code].....
So the issue is: Only the first images in my Vector are drawing. Upon further inspection, I found that the completeHandler was only being called once (I put a trace in the complete handler to check). However, the Loader is invoking load everytime the loop iterates. I tried instantiating separate loaders for each resource, just to see if it would work, but I had no luck with that. Do I need to make separate loaders and event handlers? Or am I just not using Loader correctly?

if I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?
