Uhm, right, probably lack of sleep... :-/ The following will do it:

     def sayHelloAction_(self, sender):
         info = 0
         makeAlertSheet("title", "msg", info, sender.window(), self)

     def sayHelloActionContinued(self):
         print self.x

     def sheetDidEnd_returnCode_contextInfo_(self, sheet, returnCode, 
info):
         self.x = returnCode
         self.sayHelloActionContinued()
