Re: [rules-users] NPE in SlidingTimeWindow$SlidingTimeWindowComparator

Hi Rob, Can you please provide the test case (open a JIRA with it) or at least a description of what kind of events are you feeding in and with which frequency so that we can try to reproduce the problem? The NPE where you mentioned is the symptom... the problem is elsewhere... Edson 2011/10/6 Rob Crawford <crawford(a)kloognome.com&gt; I'm getting a null pointer exception on either line 232 or 233 of SlidingTimeWindow. The only window I'm using is: rule "Mark up to date" timer(int: 5m) when $store: Store() exists (SensorReading (this.store == $store) over window:time(5m)) then ... end The rule never fires; this happens when the sliding time window is expiring tuples. It appears the comparator needs to handle nulls, but there's nothing in the JavaDocs about that. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli JBoss Drools Core Development JBoss by Red Hat @ www.jboss.com _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
