Edson Tirelli closed JBRULES-2294.
----------------------------------

    Resolution: Done


A modify or update action is broken into a retract+insert operation. When an event is expired, it is effectively removed from the node memories, preventing new matches from occurring and making further retractions useless. Although existing activations are preserved for future executions. 

A bug in the "insert" half of a modify/update operation was causing rules dependent on an event to be re-activated, even if the event was already expired. Later, when these activations were fired, a NPE was raised because the events were no longer accessible.

The "insert" algorithm was fixed to not reactivate rules based on expired events, preventing the NPE.
