According Adobe help for HTTPStatusEvent. If status coded cannot be get, it returns 0. I've similar problem right now, that I can not get status 500. Problem is that in browser it's not working (status = 0) in AIR all works correctly (status = 500). It's said that status is not correctly send to Flash Player. Do not know why, but this is current status...
Can anyone tell us if there is any workaround?
