Hi Wolfgang,
The below code which you wrote is very appropriate but where should we
mention on which collection we are traversing the conditions on .
Like in collect
$alarms : ArrayList(size>0) from
collect ( Alarm( ...... ) from av.getAlarms() )
Thanks & Regards,
Hari Kishan T

Here is an example:
$av: List() from accumulate ( $a: Alarm( ...select
"interesting" alarms... ),
init( List<Alarm> alarms = new ArrayList<Alarm>(); )
action( alarms.add($a); )
reverse( alarms.remove($a); )
result(alarms) )
To select "interesting" alarms, separate the constraints for
fields
"activation" and
"geofenceCustomer" with a comma (which acts like a logical
"and").
