<div><br></div> Hi Rob,<div><br></div><div> 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?</div>
<div><br></div><div> The NPE where you mentioned is the symptom... the problem is elsewhere...</div><div><br></div><div> Edson<br><br><div class="gmail_quote">2011/10/6 Rob Crawford <span dir="ltr"><<a href="mailto:crawford@kloognome.com">crawford@kloognome.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I'm getting a null pointer exception on either line 232 or 233 of SlidingTimeWindow. The only window I'm using is:<br>
<br>
rule "Mark up to date"<br>
timer(int: 5m)<br>
when<br>
$store: Store()<br>
exists (SensorReading (this.store == $store) over window:time(5m))<br>
then<br>
...<br>
end<br>
<br>
The rule never fires; this happens when the sliding time window is expiring tuples.<br>
<br>
It appears the comparator needs to handle nulls, but there's nothing in the JavaDocs about that.<br>
