Case solved.
I used invalid URL, that why request handler didn't recognize the
service call.
Following is the code that works:
rpc.py:
-------------------
from gluon.tools import Service
service = Service(globals())
def call():
session.forget()
return service()
@service.amfrpc3("mydomain")
def test():
return "Test!!!"
Flex

{
trace(event.result.toString());
}
private function faultHandler(event:FaultEvent):void
{
trace(event.fault.message);
}
private function fire():void
{
amfService3.test();
}

Massimo, thanks for your answers and sorry for trouble!
