"HAVING NOT LIKE" isn't working

Question

When I wanted to sum the value of all inputted device data except one type I had to put this...
SELECT AttributeName, DateAdd(minute,-5,System.TimeStamp) as WinStartTime, system.TimeStamp as WinEndTime, DeviceId, Avg(Value) as Value, Count(*) as EventCount
FROM input
GROUP BY TumblingWindow(minute, 5), DeviceId, AttributeName
Having 'OK' = CASE
     WHEN  AttributeName LIKE '%/pir/%' THEN 'PIR'
     ELSE 'OK'
END
 ...instead of simply saying...
SELECT AttributeName, DateAdd(minute,-5,System.TimeStamp) as WinStartTime, system.TimeStamp as WinEndTime, DeviceId, Avg(Value) as Value, Count(*) as EventCount
FROM input
GROUP BY TumblingWindow(minute, 5), DeviceId, AttributeName
Having  AttributeName NOT LIKE '%/pir/%'
It accepted the "NOT LIKE" version, but didn't produce any output.
Does anyone understand why NOT LIKE doesn't work in this scenario?
Thanks in advance,
Peter

Hi Peter,
Could you please try your scenario again? We deployed a service change recently which should support this scenario.
We have a different issue where testing of queries in the browser (without starting a job) does not have this fix yet, that change should be rolled out as soon as it is ready.
