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.

With kind regards,

Mike

Hi,
I have scenario where I need to compare attributes of two different instances of an object in the decision table.

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.
