I'm using custom renderer with s:SWFLoader inside to display clients swf avatars in s:List. useVirtualLayout is "on".
When new client arrives (or leaves chat) s:List send new data to the renderers.
So SWFLoader in renderer have to load new data. And as a result we have flickering. When swf avatar disappears for second and appears again.
I've resolved this issue when all avatars was just images. I've saved content from Loader and used it as data source for s:Image.
But with swf avatars this approach does not work because after adding on stage we cannot change parent of the AVM1Movie (have not tried another version because i have to support this one too).
I've looked in SWFLoader source code and found that Loader added on stage before loading data.
Also i've tried to load swf to ByteArray and call loadBytes. But flickering still exists.
And i've tried to return Loader as a source.
So what will you recomend to do in this situation? Is swf caching possible?

I'm loading in an external image (a book cover from goodreads.com) into a library viewer AIR app (used on ipad and in-browser) running on Starling (in case you need to know). After it loads, the cover should be clickable to take further action.
This all works fine on ipad and when directly built from FlashDevelop, but when it's viewed in-browser, click events don't do anything on the loaded images. It'll work on my embedded placeholder bitmaps no problem (sitting in a "Book" class extending Sprite).
It seems to be a security problem, but if it was, I'd expect the image to not load at all. But instead it loads but isn't interactive anymore. I've tried various things like:
Add loader and click listener to the Book object
Add loader.content as Bitmap and click listener to the Book
Create a BitmapData and draw the Loader.content, then add the resulting Bitmap (it's blank in-browser, but works perfectly when built from FD)
Add loader and place a transparent sprite on top of it, add listener to the sprite
Has anyone had this problem? Would anyone know a work-around?
Thanks!
This was a sand-box problem.
I think it's intentional; you shouldn't be able to hot-link other site's assets unless given express permission.
I fixed this by only pulling images hosted locally and using crossdomain.xml to make sure there was no lookup issues when www.domain.com and domain.com were different.
I am working on embedding a SWF that is just a converted PDF created with InDesign. The SWF is 15 pages, 1 page per frame. It does include TLF text and there is no way around that unless the document is completely recreated in Flash. The problem is that when I load the SWF into my application, I never have access to the root MovieClip.
this.loader = new Loader();
this.loader.contentLoaderInfo.addEventListener( Event.INIT, this.loaderInitHandler );
this.loader.contentLoaderInfo.addEventListener( Event.COMPLETE, this.loaderInitHandler );
this.loader.load( new URLRequest( "assets/doc.swf" ) );
When I look at the loader after both the INIT and COMPLETE events as well as later on by stopping the app in debug mode, I do not see a MovieClip. Instead, the loader.content is of type doc_fla.MainTimeline__Preloader__ which contains two children, an empty Shape and another Loader. That loader, when checking INIT and COMPLETE events results in the exact same situation and it appears to be a never ending line of Loaders whose contents are "Preloaders".
Could anyone shed some light as to what is causing this or how I might fix it? I've poured a good 2 hours into solving this and I am no closer to a solution than when I started.
ActionScript Mobile project
Compiling using AIR 3.6
Testing in emulator as well as on iPad and on Nexus 7
I recompiled the SWF and embedded the TLF libraries (under ActionScript settings, just set the TLF swc which was already there to be embedded) in it and this seems to have fixed the issue. I swear I had tried that before to no success, but it worked this time.
The code at the bottom of this post nests an AS2 "player" inside a Flex app (AS3). Look at the part that says "[AS2 player swf]". That AS2 player swf has almost no code - just one function that loads an asset from a remote server. Very simple:
this.onLoad = function(){
content.loadMovie("http://URL_TO_REMOTE_SWF");
};
And it has no other assets. Just one MovieClip - "content".
So we've got a Flex app that loads an AS2 swf that loads a remote swf. No dice. Remote swf doesn't load and display. No errors reported.
Important: The AS2 app on its own works. If I go navigate to it in my file system and double click, remote swf does indeed load and display. So I've established that the unwrapped AS2 swf player works and does indeed load remote swf's. Something about nesting that player inside the Flex app creates a problem. Are you not allowed to do this - 3 levels of swf nesting (child - parent - grandparent)?
UPDATE: Target remote swf's load and display fine directly in Flex as well (skipping AS2 swf). So problem doesn't appear to be with AVM1/AVM2 discrepancy between target content and Flex app. Could be AVM1/AVM2 problem with how the Flex app displays the AS2 swf but only when it contains content.loadMovie("http://URL_TO_REMOTE_SWF"). Loads and displays without that line.
UPDATE: This is a Flex packaged IOS application and thus is subject to ActionScript restrictions for dynamically loaded code. But it doesn't work in a regular Flex (non packaged IOS) app either which is not subject to these limitations. THE FOLLOWING CODE SHOULD WORK AS FAR AS I CAN TELL IN A REGULAR FLEX BROWSER BASED APPLICATION.

Since all Sprites and MovieClips are both display objects and display object containers, you could theoretically keep nesting them forever. There are physical restraints, of course, but I see no reason why there should be a limit other than memory and processing power (at some point, refreshing the screen will become sluggish, and eventually painful to wait for).
I've searched the web to see if I could find any information about a built-in limit enforced by the AVM, any documents or error codes that would suggest there is one, but I couldn't find anything at all. Of course, that doesn't mean there isn't - it just means the limit hasn't been reached by many people yet ;)
So if anyone else knows more...
EDIT
Since the information about your loaded MovieClip is new, here's my update: AVM1 (AS1 & 2) SWFs don't always execute in the same way when loaded into an AVM2 (AS3) movie. This has nothing to do with the number of nested display objects. I originally thought this was because the _lockroot property was removed in AS3, but I've searched a bit and found out it is assumed true by default, and should therefore not be a problem.
There may be many things about your scenario that are different from when the file runs on its own, and I would start by looking at these:
Do you use relative path names to load other data into the AS2 swf?
Do you get any error messages (particularly, security sandbox violation errors)?
Does your AS2 SWF rely on external variables to be set (FlashVars)
Does your AS2 SWF need ExternalInterface access?
FINAL EDIT
Since this new info has just come up:
There is absolutely no way to execute dynamically loaded AVM byte code on an iPad at runtime, for the same reason that there is no Java VM and no Flash Player for iOS: Apple does not allow the execution of dynamically loaded byte code at all. Period.
Hence, you can load and play SWF animations, but not ActionScript. It will simply be ignored. Also, neither of the apps that you did run is in fact AVM byte code - they are compiled into LLVM byte code instead.
You will have to find a way to check for the end of the animation that does not involve stop() commands. Perhaps this can be done by checking frame numbers from your AS3 container?
To answer you question directly, yes, you can load AS2 swfs that way. And you code looks correct to me.
I suspect it is loading the AS2 swf fine, but that the AS2 swf is not initializing correctly for some reason. Perhaps it is a video player that has no visible assets besides the loaded video. AS2 tends to fail without throwing errors, which makes it hard to debug. I would suggest publishing an AS2 swf with some graphics in it but with no code that could fail. No code at all. Maybe just a timeline animation of a moving circle or something, then load that. In that way you can eliminate your Flex code as the source of the problem.
If it turns out that your test movie works, then you will need to determine what resource the loaded swf is expecting that it is not receiving.
So, hypothetical situation here:
I have an SWF that's 30MB. Sound files (music) make up 25MB, art and other things make up the remaining 5MB.
Would it be possible for me to load the 5MB of necessary art and other things first to allow the user to operate the app, then after that's all loaded and they are operating the app, load the remaining 25MB of sound files in the background?
UPDATE:
Loading SWF (or other entities) externally is not an option.
You can do this by modifying the compilation settings and strategically placing the sound.
By default, anything placed on the timeline will be loaded sequentially; the Flash Player will play the SWF as soon as the first frame is loaded. If you use the default compilation settings, all library content will be placed in the first frame, so the movie doesn't start until everything is available.
You can modify these settings, however, to allow for a more sequential load order: For each of your library elements, you can uncheck "export into frame 1" in the properties window. Now these elements won't be loaded, until they appear in the main timeline. This way, if you place your content carefully, you can allow for all important elements to be loaded in the first frame, or if you have a progress bar, until the main movie starts, while all streaming elements load with the animation, which has to be placed accordingly. Make sure though, that you don't leave anything out (by not placing it on the timeline), or call elements from ActionScript before they are loaded completely. It is very important to test this thoroughly, because if anything goes wrong in the load order, your entire SWF might stop working.
Also, remember that the SWF loads sequentially: If you have a sound in, say, frame 300, and another in frame 1000, the one in 300 will be loaded first. If you jump to frame 1000 from a menu in frame 10, you have to take into account that the frame might not be loaded yet. So there has to be some sort of checking mechanism (framesLoaded) and/or dialog to inform the user about additional loading time, and prevent the application from crashing.
I load swf files continuously, but if one of the swfs has some defective code such as Mouse.hide() the mouse disappears when the swf is loaded. I want to constrain such malicious code in loaded swfs.
There is also another problem related to containing loaded or loading swfs. When I load a swf which loads another swf to operate, It never completes loading (Event.Complete of contentLoaderInfo) because it needs another swf to load. However, the swf should be loaded before it runs. Since loaded swf is as-2, loader does not give any error. I am also suspicious whether or not it will give error if it is as-3.
Check the LoaderMax classes from greensock.com . This should help solve the problem of swf loading other swf before running, since you can listen to the overall loading progress and react accordingly.
