[omniORB] Questions related with Event Channel in omniORBpy

[Wang, Xiaohui]

Hi:
	I am currently writing a small program to see how event service
works in omniORBpy. I am using omniORBpy-2.2
on NT platform.

	My program is pretty simple like the following:

	import sys
	from omniORB import CORBA
	import CosEventComm, CosEventChannelAdmin

	orb = CORBA.ORB_init(sys.argv, CORBA.ORB_ID)

	poa = orb.resolve_init_references("RootPOA")

	# Get the EventChannel instance using ior
	# My event service is from Visibroker
	fp = open('ior')
	ior = fp.readline()
	fp.close()

	eventObj = orb.string_to_object(ior)

	# Get the event channel
	myEventChannel = eventObj._narrow(CosEventChannelAdmin.EventChannel)

	# Invoke the consumers
	forConsumer = myEventChannel.for_consumers()

	...

	When I run the program, the following exception was obtained at the
step of invoking the consumers:
	
		Traceback (most recent call last):
  		File "Y:\python_corba\PythonEvent.py", line 53, in
-toplevel-
    			forConsumer = myEventChannel.for_consumers()
  		File
"C:\omniORBpy-2.2\lib\python\omniORB\COS\CosEventChannelAdmin_idl.py", line
382, in for_consumers
    			return _omnipy.invoke(self, "for_consumers",
_0_CosEventChannelAdmin.EventChannel._d_for_consumers, args)
		COMM_FAILURE: Minor: COMM_FAILURE_UnMarshalResults,
COMPLETED_YES.

	Anybody has any ideas on what happened here? Any useful information
is highly appreciated.

Thanks,

Xiaohui
