Thanks for the report and the information about this issue. I will make sure 
this gets 
addressed in the final release of 1.3

more update on this:

- This error stops if ProgressiveLoading is set to 'false'

- Also, further search about this on forums indicates that
the error seems to be related to removing of non-existent
child object which is happening inside loadBytes() 
(AVM2Loader.confirmBytesLoaded())
.I could reproduce same error by calling _loader.unload() just before
loadBytes() in confirmBytesLoaded(). More info at: 
http://www.senocular.com/flash/tutorials/runtimeerrors/

- For now, I have wrapped this error causing code in confirmBytesLoaded()
inside try/catch block with trace inside catch to get notification. The viewer
fails to load remaining pages after this error is thrown.

Hi, actually having a problem to reproduce this... starting to wonder if its 
about the content-length on your web 
server not getting returned and this resulting as a consequence... what flash 
version on firefox/ie are you 
running?

Please try the attached build and see if you can reproduce the issue. Have made 
some adjustments to how the 
last part of the swf is loaded

Will try your build and let you know.

Hi Erik,

The error condition was reproduced with the FlexPaperViewer.swf you 
had attached. I am attaching a screenshot or the error in browser.

Web Server: Apache 2.2 on localhost (WinXP SP2)
Browser: Firefox 3.6.2, with Flash Player plug-in ver 9.0.124.0

This must be an old flash player 9 runtime bug that has been fixed in version 
10 and above because I can't 
reproduce it in version 10. I'll do some testing in v9 and tell you how it goes

I was able to reproduce this in Flash Player 9 and I think I've found a 
solution to it by basically retrying the 
operation that fails when it fails.. Have not been able to reproduce the issue 
in this build. Thanks for your help in 
finding this issue. Please tell me how it goes. 

Please see attached.

Yes. It doesn't throw the exception now.
Just tried the swf you sent several times.

Thanks for all the efforts.
