Issue with Drools Fusion "during" temporal operator - drools

Question

I've started to work with Drools Fusion and faced strange issue with during temporal operator. For a reason I cannot make it too work though for example after operator is working fine.
Here is declaration of my event - it just contains an intervals of particular type:
declare WorkingDayInterval
#role(event)
#timestamp(event_ts_local)
#duration(duration_in_seconds)
end
Here is my rule:
rule "Idles in Processing period"
when
$processing : WorkingDayInterval( subcategory == "processing")
$longIdle : WorkingDayInterval(this during $processing, subcategory == "idle",duration_in_seconds > 600)
then
System.out.println ("Bad Idle Event:");
System.out.println ($processing.event_ts_local);
System.out.println ($processing.duration_in_seconds);
System.out.println ($longIdle.event_ts_local);
System.out.println ($longIdle.duration_in_seconds);
end
When I run it nothing is fired.
However when I change during to after I get following results:
Bad Idle Event:
Mon Feb 25 05:19:00 MSK 2013
2350
Mon Feb 25 05:20:00 MSK 2013
901
and looking at the values I clearly see that based on start timestamps and durations second event is inside the first event and so duration should have been fired.
Is it a bug in the Drools Fusion or I am doing something wrong?
BTW - I am running in a Cloud mode

Answer 1

I think the problem is that you are assuming that #duration is measured in seconds when in reality Fusion expects it to be expressed in milliseconds. So, in your case, $processing event starts at 05:19:00.00 and ends at 05:19:02.35 and $longIdle starts at 05:20:00.00 and ends at 05:20:00.90. As you can see, $longIdle during $processing is false but $longIdle after $processing is true.
Hope it helps,
