Omniorb event channel question

[Attila Rajmund Nohl]

Hello!

I'm using python 2.3.5 on Linux with omniORB 2.6. I'm trying to create
an object that shall listen on an event channel, but the registration
doesn't work. My code is:

class EventListener(CosEventComm.PushConsumer):

def __init__(self):
pass

def push(self, data):
print data.typecode().kind()
print data.typecode().name()

def disconnect_push_consumer(self):
pass

[... initalize the ORB ...]

channel = orb.getRootInterface(channelname)
chadmin = channel.for_consumers()
supplier = chadmin.obtain_push_supplier()
listener = EventListener()
supplier.connect_push_consumer(listener)

Unfortunately I get the following error at this point:
omniORB.CORBA.BAD_PARAM
Traceback (most recent call last)

test.py
70 supplier = chadmin.obtain_push_supplier()
71 listener = EventListener()
---> 72 supplier.connect_push_consumer(listener)
73
74

CosEventChannelAdmin_idl.py
in connect_push_consumer(self, *args)
122
123 def connect_push_consumer(self, *args):
--> 124 return _omnipy.invoke(self, "connect_push_consumer",
_0_CosEventChannelAdmin.ProxyPushSupplier._d_connect_push_consumer, args)
125
126 __methods__ = ["connect_push_consumer"] +
_0_CosEventComm._objref_PushSupplier.__methods__

BAD_PARAM: Minor: BAD_PARAM_WrongPythonType, COMPLETED_NO.

What am I missing? The ORB works otherwise.

Bye,NAR

channel = orb.getRootInterface(channelname)

chadmin = channel.for_consumers()
supplier = chadmin.obtain_push_supplier()
listener = EventListener()
supplier.connect_push_consumer(listener)

Not sure, but I guess you want a

listener._this()

here.

That worked, thanks. However, the event receiving doesn't seem to work.
I've started the ORB with
corba.orb.run()

but the push() method of the EventListener object doesn't get called (or
at least the print() calls in the method are not executed) and the event
sender program is blocked in the push() call. Do I need something else
to set up?
