Response for incorrect Place in RequestStartPlaceAgentStateReporting

My app needs to receive unsolicited messags from the ixnServer, so I am sending a RequestStartPlaceAgentStateReporting for each place.

	
RequestStartPlaceAgentStateReporting reqListen = RequestStartPlaceAgentStateReporting
						.create();
				reqListen.setPlaceId("PlaceOfGold");
				reqListen.setTenantId(101);

isProtocol.requestAsync(reqListen , null, new MessageCompletionHandler(), 10000);

My problem is that I cannot receive a response telling me an incorrect place is specified in the request. My app needs to know if a request was unsuccessful.

Please help.
