Re: [rules-users] Odd rules execution for expired events

Not only that. It can also cause NPE to be thrown. That would happen if there is such a rule: rule "Update Recording" when $m : Motion() $r : Recording() then System.err.println("Recording: " + $r); retract($r); end then this rule may be executed multiple times and $r could be NULL (since there should be only one instance of a Recording at most). I would call it a bug. -- View this message in context: http://drools.46999.n3.nabble.com/Odd-rules-execution-for-expired-events-...
