I don't understand your explanation. When a callback returns a Deferred itself, the main Deferred object waits for its completion before continuing. This is IMO the best feature of Deferreds! I often write code like the function above, so I would like to understand why it does not work in this case. -- Amaury Forgeot d'Arc _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
