Re: Event Service problem

Hello,

I solved it by passing null to connect_pull_consumer():

try{
	    eventChannel = EventChannelHelper.narrow(obj);
	    consumerAdmin = eventChannel.for_consumers();
	    pullSupplier = consumerAdmin.obtain_pull_supplier();
	
	    pullSupplier.connect_pull_consumer( null );

	    event = pullSupplier.pull();
}(...)


And did the same to connect_push_supplier() on the server side - it's all
working OK now. Here are two fine links on this matter, if anyone ever needs
it:

Thanks for the help :)
