Flex-AIR: Main Thread (Suspended).....WHY??

Question

Whenever I debug my AIR app it keeps suspending at a certain line of code...it doesn't give me a reason why, it just says Main Thread (Suspended) No error, no breakpoint at this location either. If I comment out the code so that, that line does not execute, it just does the same thing on a different line of code.

I have no clue why.... What should I do?

Thanks!!

Here is the function it happens in:

public function update (): void
     {
      dispatchEvent ( new Event ( EVENT_UPDATE_DOWNLOAD_STARTED ) );

      var request: URLRequest = new URLRequest ( _newVersionUrl );
      urlStream = new URLStream();
      updateFileData = new ByteArray();
      urlStream.addEventListener ( Event.COMPLETE, streamDownloadComplete );
      urlStream.addEventListener ( ProgressEvent.PROGRESS, streamDownloadProgress );
      urlStream.addEventListener ( IOErrorEvent.IO_ERROR, versionCheckIOErrorHandler );
      urlStream.load(request);
     }

this is the line it suspends on:

updateFileData = new ByteArray();

updateFileData is defined outside the function like so:

protected var updateFileData: ByteArray;

I should mention...this code is the code that Updates the version of air..could this be suspending because its trying to update while in adl.exe?

Thanks

Answer 1

Are you using FlexBuilder? If you are, have you made sure there isn't a breakpoint set somewhere in your SDK source (I sometimes do this by mistake)? Try checking, via the Debugging profile (Window > Perspective > Flex Debugging), the the Breakpoints view to see whether there's anything in there you don't recognize. Also, when you're hung up, try stepping through the code (e.g., using F5 or F6) to see if that helps you figure out where the debugger's stopped.

Not 100% sure, because you're not hitting the error but - This might be an issue caused because the docs say you can't do the update while in the debugger:

When testing an application using the AIR Debug Launcher (ADL) application, attempting to update the application results in an IllegalOperationError exception.

This is from the livedocs.
