ty ro commented on FLEX-34834:
------------------------------
okay. after spending hours trying to get the sdk to compile i've fixed it but
its not a real patch, more like a quick fix.
long story short, the permission error is just a red herring. the real problem
is that event.complete is firing before the file has actually completed loaded
which means when loadcompletehandler fires, theres nothing for it to work with
quite yet.
"
loaderInfo.addEventListener(Event.COMPLETE,loadCompleteHandler,false,0,true);
" should be line 742 or close to it
the temporary fix is simply to do this is to encasupulate some of the code in
the loadcompletehandler function
in a for loop that will act as a rudementary timer and delay the code from
firing before the loader has completed loading
callLater sure would come in handy here.
btw this bug is present in all versions of apache flex sdk that use the
textlayout framework 3
my hotfixed loadcompletehandler:
" private function loadCompleteHandler(e:Event):void
{
CONFIG::debug {
Debugging.traceFTECall(null,null,"loadCompleteHandler",this); }
removeDefaultLoadHandlers(graphic as Loader);
CONFIG::debug { assert(okToUpdateHeightAndWidth == false,"invalid
call to loadCompleteHandler"); }
for (var i:int = 0;i<30000;i++)
{
if (i == 29900){
okToUpdateHeightAndWidth = true;
var g:DisplayObject = graphic;
_measuredWidth = g.width;
_measuredHeight = g.height;
//bug #2931005 TLF cannot show Flex SWF after loading
it as an ILG
if(graphic is Loader && Loader(graphic).content != null
&& Loader(graphic).content.hasOwnProperty("setActualSize") &&
(!widthIsComputed() || !heightIsComputed()) )
Object(Loader(graphic).content).setActualSize(elementWidth, elementHeight);
else
{
if (!widthIsComputed())
g.width = elementWidth;
if (!heightIsComputed())
g.height = elementHeight;
}
if (e is IOErrorEvent)
changeGraphicStatus(e);
else if (widthIsComputed() || heightIsComputed())
{
g.visible = false;
// triggers a delayedElementUpdate
changeGraphicStatus(InlineGraphicElementStatus.SIZE_PENDING);
}
else
changeGraphicStatus(LOAD_COMPLETE);
}}}"

> Environment: windows
> Reporter: ty ro

> SecurityError: Error #2122: Security sandbox violation: Loader.content:
> http://mydomain.com/Client/myapplication.swf cannot access

> The image actually loads successfully in-spite of the error, but it doesn't
> being measured correctly, so the image can exceed the component's
> boundaries and overlap the text after it.
> using .swf debug on desktop does not reproduce this. using on browser does
> regardless if it is debug release or build release.
