[PEAK] problem with peak.io_events

[Vladimir Iliev]

Hi,

I'm trying to create simple event driven app which should listen for 
signals but my callback func never gets called no matter what signal I 
send to the app (see the attachment). What am I doing wrong ?

class MyTask(AdaptiveTask):

        ss = self.lookupComponent(ISignalSource)
        ss.signals(tuple(signal_names)).addCallback(cb)
	MyTask(self, runEvery=1)
    _setup = binding.Make(_setup, uponAssembly=True)

class MyApp(EventDriven):
    commands = binding.Make(Comp, uponAssembly=True)

if __name__ == '__main__':
    MyApp(config.makeRoot()).run()
