I've debugged Flex for a while and found out that "Service.ResourceNotFound" comes over from the server. Since I don't have a clue how to debug web2py, I just dig in pyamf sources untill I found out that Service.ResourceNotFound is a string message of UnknownServiceError which is raised in \pyamf\remoting\gateway\__init__.py at line 395 in 'def getServiceRequest'. I can't understandf much from the code of that function, because I'm not too savvy with Python syntax or pyamf classes but I'm qute sure that the problem is there. Or at least, this is where the request gets rejected. Is there any way to debug this stuff directly? SOS!
