I tried what you said, as:
-----
class Event_1(event.EventBase):
def __init__(self):
super(Event_1, self).__init__()
self.msg = 'event 1'
class Hehe(app_manager.RyuApp):
def __init__(self):
super(Hehe, self).__init__()
self.register_observer(Event_1, self.name)
print 'my name is ', self.name
self.ping()
def ping(self):
self.send_event_to_observers(Event_1())
print 'pinging...'
@handler.set_ev_cls(Event_1)
def pong(self, event):
print 'Got ya', event.msg
-----
but after ping(), pong() is not triggered
