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 -----Original Message----- From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of Wolfgang Laun Sent: Wednesday, September 28, 2011 3:39 PM To: Rules Users List Subject: Re: [rules-users] Getting Exception while running rules continuously on the Event Streams from Mule Component. 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"). -W 2011/9/28 Hari Kishan <harikishan.tamm...@pass-consulting.com>: > @wolfgang Yesterday you told me to use accumulate instead of collect.
