Get and compare object with previous version


I have use case, when I need to subscribe to object changes. Object has an int field. I need to execute logic in subscriber (Notify Listener Container) only in case if (previous version of the object had value = 0 and current value > 0) OR (previous value >0 and current value = 0). But in notify containers and polling containers I didn't find a way - how I can take previous version of the object.

Is it possible to cover this use case? Because I need to handle this situation in Near Real Time.

Can you try adding a new field to your class for the previous value? Then you can use a SQLQuery to receive notification on objects that match the SQLQuery.
