Hi again,
Okay, I'm getting closer now. The statement from the trace that
omniDynamic is not being linked is just misleading, it is the same
for the type test stuff in omniORBpy/examples (which do work).
Instead it seems, as it is not possible to send some object
reference using an Any with typecode = CORBA._tc_Object:
I have meanwhile identified that the problem obviously depends
on the filterable data part of the structured event instance that is
going to be sent. One of the items in the property list is used to
transfer an object reference with the event. As a 'toy' item for
testing I use the root naming context of omniNames.
The transmission of the structured event is only possible if the
typecode for the Any value is either CosNaming._tc_NamingContext
or CosNaming._tc_NamingContextExt. Formerly, I used
CORBA._tc_Object which has led to a fatal exception as described
previously.
I can hardly believe that the behavior experienced is intended like this?

Subject: [omniORB] Fatal exception during event sending
Hi,
using Python 2.0 on Solaris 2.7 together with omniORB and omniORBpy
I get a fatal exception when working with omniNotify. I can create a new
event channel, connect a push consumer and a push supplier to it
(in separate Python processes). When I try to push the event to the
channel like this:
evt = CosNotification.StructuredEvent(evt_header, fd_body,
txn_val)
self.str_px.push_structured_event(evt)
I get:
Run-time exception error; current exception: fatalException
No handler for exception.
I know that this is of little help... What could I do to give you (and me)
some
hints about what is happening here?
Lars
