I am trying to configure a filter for a particular driver developed for Zigbee protocol. Events from the dirver are arriving in the inbound queue. I am trying to write some buisness logic to check the incoming events in the filter by extending the Simple Filter/ Abstract filter. I am not able to trace the incoming event. The event is sent using the oracle.edge.common.Event class. The postFilter , preFilter methods in the filter is not able to receive the event.
