me too, may be its because of the way I'm calling the chain: return ( self.abc1(). addErrback(self.handleFailure1). addCallback(self.abc2,args). addCallback(self.abc3). addErrback(self.handleFailure2) )
I see no call to self.handleFailure1() at all, abc1() just fail on exception (if it was raised). Quoting "Valeriy Pogrebitskiy" <vpogr...@verizon.net>: > I am confused...
