Thanks Mike. Will give it a try Regards, Shobha M From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Michael Anstis Sent: 10 August 2012 PM 02:16 To: Rules Users List Subject: Re: [rules-users] Decision table help In DRL terms this is quite simple:- when $instance1 : ObjA( $mailID : mailId ) ObjA( this != $instance1, mailId != $mailId ) then ... This translates to a XLS decision table like this:- | CONDITION | CONDITION | CONDITION | +---------------+-----------------+------------------+ | $i : ObjA | ObjA | +---------------+-----------------+------------------+ | $mid : mailId | this != $param | mailId != $param | +---------------+-----------------+------------------+ | 12345 | $i | $mid | There are no doubt other approaches.

The scenario is - say I have 5 instances of an object ObjA. ObjA has an attribute mail_id. I need to compare the maild_id attributes of the ObjA instances to figure out if they do not match (Ex: instance1.maild1 <> instance2 maild) Can you please let me know how this can be achieved using the decision table.
