Re: Re: Re: Re: Re: Re: [Flashcoders] Misreporting instanceof operator.
Again, how peculiar. I'd love to take a look at the internals of
MovieClip and Flash's loader system to see what's causing that
particular glitch!

Okay,
I have fixed the problem. I would say that this is certainly bug with
Flash, but there is a work around. Thanks to Keith Peters for
mentioning this to me last night.
So here's the deal... Back in the day before MovieClipLoader when you
wanted to load and external SWF, you had to check a property of the
MovieClip to see if it existed before you could manipulate it. You
needed to create an interval that would check to see if it's
initialized in this way. This all makes sense to me, but what doesn't,
is that you can't just check that any property of MovieClip was set.
There is a magic property that seems to indicate that the MovieClip is
fully initialized. That property is _width.
So with this in mind I added a check to the onLoadProgress event like so:
private function handleLoadProgress(targetMC:MovieClip,
loadedBytes:Number, totalBytes:Number):Void
{
if (MovieAsset.HIDE_WHEN_LOADED)
{
if (targetMC._width != undefined || targetMC._width !=
0)
{
targetMC._visible = false;
}
}
}
Now, how's that for obscure? It does fix the issue, and instanceof is
indeed a MovieClip once again. Oh, and even better, _visible works
like a charm.
Thanks again to all those that helped out with this one.

Re: Re: Re: Re: [Flashcoders] Misreporting instanceof operator.
Okay, weirder and weirder: On my local machine loading from a local file, loading .swf v6 gives instanceof MovieClip=false and v7 and v8 give instanceof MovieClip=true. On a remote machine loading from that same remote machine, loading .swf v6 gives instanceof MovieClip=false and v7 and v8 give instanceof MovieClip=true. On my local machine loading from a remote machine, all versions give instanceof MovieClip=false. On a remote machine loading from a different remote machine, all versions give instanceof MovieClip=false. My initial thought is it must be a cross-domain scripting issue - i.e. the app wouldn't let you check the instanceof because of a domain scripting policy (see http://www.adobe.com/devnet/flash/articles/fplayer_security_04.html). But I've tested it with System.security.allowDomain() and checked scripting between the two movies, and even when cross-domain scripting works perfectly (no sandbox violations) the instanceof still returns false. (I'm not 100% sure whether I've got the System.security settings right - but I can read vars in the loaded movies and vice versa, so that sounds pretty correct to me.) I still think that's the most likely candidate - that it's _something_ to do with the sandbox/security system getting in the way. After all, a common feature is that v6 .swfs fail all the time - and we already know that a v6 movie can never share a global object with a v7 or v8 movie. I'm certainly running out of ideas for a simple fix, here - and it's definitely not the loading code, it's a 'feature' or bug in the Flash Player. Hope some of this helps!

Re: Re: Re: Re: [Flashcoders] Misreporting instanceof operator.
Oh, I should add, this is after I commented out the line:
if(targetMC instanceof MovieClip == false) targetMC.__proto__ = new MovieClip();
from MovieAssets - which I assume was your temporary hack to fix
things. It all works for me without this line.
Cheers,
Ian

Hi Chris,
I've tried that (with a bit tweaking for syntax errors) and it all
works fine - instanceof returns the correct results. This is loading a
clip I created from scratch (Flash 8, WinXP) - if you have a sample
clip I can try that's failing for you, that's be good.
However, I did have to correct the trace statements:
trace("Is this a movieclip:"+clip instanceof MovieClip); // Always
outputs 'false'
trace("Is this a movieclip:"+(clip instanceof MovieClip)); // Always
gives the correct answer.
It's not something as simple and silly as that, is it? I assume not. :-)

Hi Chris,
Having had a trawl through the source code, I see what you're
getting at. The fact that MovieAsset doesn't extend MovieClip is
nothing to do with the problem; MovieAsset wraps a MovieClip property
and passes that back, and that should be fine.
I've no idea where it's going wrong, I'm afraid - the code all looks
sane and clean to me. Did you say you're only getting this issue from
MTASC compiled .swfs..?

Hi Ian,
Thanks for looking into this.
I did indeed try running it with Flash compiling. Try this in an FLA
and you should see the same results:
import org.osflash.fling.util.assets.MovieAsset;
MovieAsset.setHideWhenLoaded(true);
var asset:MovieAsset = new MovieAsset();
asset.addEventListener(AssetLoader.ASSETLOADCOMPLETE,
Delegate.create(this, handleAssetComplete));
asset.addEventListener(AssetLoader.ASSETLOADPROGRESS,
Delegate.create(this, handleAssetProgress));
asset.addEventListener(AssetLoader.ASSETLOADERROR,
Delegate.create(this, handleAssetError));
asset.setName("testMovie");
asset.setAutoCreateContainer(true);
var mc:MovieClip = _level0.createEmptyMovieClip("testHolder_mc",
_level0.getNextHighestDepth());
asset.setTarget(mc);
asset.setSource("testassets/test.swf");
asset.load();
function handleAssetComplete(eventObj:Object):Void
{
trace("loaded");
trace("Movie: " + asset.getResource());
var movie:MovieClip = MovieClip(asset.getResource());
movie._visible = true;
}
function handleAssetProgress(eventObj:Object):Void
{
trace("bytesLoaded: " + eventObj.loadedBytes + " totalBytes: " +
eventObj.totalBytes + " for " + eventObj.assetName);
}
function handleAssetError(eventObj:Object) :Void
{
trace (eventObj.message);
}

Re: Re: Re: [Flashcoders] Misreporting instanceof operator.
BTW, there is a unit test to recreate the problem. It can be found here: http://svn1.cvsdude.com/osflash/fling/DEV_Source/classes/org/osflash/fling/tests/TestMovieAsset.as See testShowMovie() -Chris On 8/23/06, Chris Allen <[EMAIL PROTECTED]> wrote: On 8/23/06, Peter Hall <[EMAIL PROTECTED]> wrote: > Perhaps you have a class associated with the symbol, which does not > extend MovieClip? > Well the instance of MovieClip, or whatever it is in this case, is a part of a class that doesn't extend MovieClip (MovieAsset). MovieAsset implemts and Asset interface and extends an AbstractAsset class that does much of the general leg work. The MovieAsset class has a method getResource() that returns an Object, in this particular case it's the MovieClip in question. So when accessing this MovieClip using this class you must call getResource() and cast it to MovieClip: var movie:MovieClip = MovieClip(asset.getResource()); movie._visible = true; You can take a look at what we are working on here: http://svn1.cvsdude.com/osflash/fling/DEV_Source/classes/org/osflash/fling/util/assets/ To replicate the problem you have to set MovieAsset.setHideWhenLoaded(true); then once the loadComplete event is triggered you try to set the MovieClip to visible: MovieClip(asset.getResource())._visible = true; You should then see that it doesn't work.

Definitely. this is a world of pain by the looks of it... have you tried loading it in without a loader, rather old style target.load(path) and see if that solves the problem. i have had some weirdness in flex1.5 with loading content as well and hacking it like this (which makes my stomach churn) has had the desired result. We tried the MovieClip.loadMovie() way of doing things and it had the same result. I assume that's what you are talking about. We are certainly dealing with one of those weird voodoo areas of Flash, so thanks for the sympathy. ;-) On 8/23/06, Chris Allen <[EMAIL PROTECTED]> wrote: > > Hi Johannes, > > Welcome back to Boston!
