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(C osEventComm.Pus hConsumer):

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.getRootInte rface(channelna me)
chadmin = channel.for_con sumers()
supplier = chadmin.obtain_ push_supplier()
listener = EventListener()
supplier.connec t_push_consumer (listener)

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

test.py
70 supplier = chadmin.obtain_ push_supplier()
71 listener = EventListener()
---> 72 supplier.connec t_push_consumer (listener)
73
74

CosEventChannel Admin_idl.py
in connect_push_co nsumer(self, *args)
122
123 def connect_push_co nsumer(self, *args):
--> 124 return _omnipy.invoke( self, "connect_push_c onsumer",
_0_CosEventChan nelAdmin.ProxyP ushSupplier._d_ connect_push_co nsumer, args)
125
126 __methods__ = ["connect_push_c onsumer"] +
_0_CosEventComm ._objref_PushSu pplier.__method s__

BAD_PARAM: Minor: BAD_PARAM_Wrong PythonType, COMPLETED_NO.

What am I missing? The ORB works otherwise.

Bye,NAR

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?
