Concurrency (ActionScript Workers) Bug in Flex Project??

Few questions.

are you on windows or mac? Which OS? Are you running this in the browser? If so which browser and what version?

You are using Beta 2 from

http://labs.adobe.com/downloads/flashplayer11-4.html, correct?

Can you share your project with us?  I want to take a look at the code to see what might be happening.

Do you get the same results when you try to run the the .swf that was already provided from examples/bin/HelloWorld/HelloWorld.swf?

You should see:

inside primordial worker

Current State: running

Background received: Hi from Main

The problem is that when you use this.loaderInfo.bytes, it takes the SWF bytes of everything in the main SWF including the Flex/Spark components, which some are prevented from working in a background worker.  So, when you create a background worker based on the SWF bytes of the main worker, you'll encounter a run time error.  Using Flash Builder 4.7, you'll see this right away as it has support for debugging Workers in the background.  I've taken the liberty to fix your code to make it work.  You'll have to create a separate SWF with all of your background worker code and then use a URLLoader object to load that SWF in to create your worker.

I'll attach the project to this thread.

Here is the updated project: https://www.dropbox.com/s/o50s10wwwg2nsdd/TestWorker.zip

Let me know if you have any issues.
