SWQL works in studio but not in Website

After migrating to NPM 12.1 I've decided to update my SQL queries to SWQL queries since row limit started to bother me and searchable textbox seems to be legit.

My swql query looks like:

select 
case when ccs.Availability=1 then 'Up' else 'Down' end as STATUS,
'/NetPerfmon/images/Small-' + case when ccs.Availability=1 then 'Up' else 'Down' end + '.gif' as _IconFor_STATUS,
n.Caption, c.Name,
ccs.TimeStamp, 
ccs.LastTimeUp, 
ccs.ErrorMessage
from 
Orion.Nodes n, Orion.APM.Component c, Orion.APM.Application a, Orion.APM.CurrentComponentStatus ccs
where 
n.NodeID=a.NodeID and 
ccs.ApplicationID=a.ID and 
ccs.ComponentID=c.ComponentID and 
a.Name like 'Windows %' and 
c.Name <> 'Task Scheduler' and
(c.Status=1 or c.Status=2) and
a.Unmanaged=0

It works perfectly on swql studio but not on custom query on website. Any comments?

Thanks.
