Is this not working for you?
obj = JSON.decode(event.target.data);
No - I get: "
1172: Definition com.adobe.serialization.json.JSON could not be found"
You have to add as3corelib.swc to your project.
Thank you very much. I went to: https://github.com/mikechambers/as3corelib and downloaded the Windows mikechambers-as3corelib-release.93-8-g24c6c16.zip file. It does not appear to contain the as3corelib.swc file.
Am I supposed to compile this SWC? I checked the README but it's not clueing me in to some obvious fact that I just don't get. I'm really sorry for the noob questions but how am I supposed to get or generate the as3corelib.swc file?
Thank you for your patience!
