Note: I am not asking about services - it works there.
I am not getting any error events, just DataEvent.UPLOAD_COMPLETE_DATA or Event.COMPLETE event with data set to the php error message response.
Is there any way to make this work like with Services CallResponder fault event ? If yes, how do I do that ?
I've been looking a few hours for this answer and I don't seem to find how to do this. Is is possible at all?
