Is it possible to have a single line of DSL convert into multiple lines of DRL? I want to hide the implementation of my rules from the user. So, using my previous post as an example: rule "group 1" when  $a : Trans( $groupValue : prodCat, $date : date )  not Trans( this != $a, prodCat == $groupValue, date < $date )  $b : LinkedList( size >= 1 ) from collect ( Trans( this != $a, prodCat == $groupValue, date > $date ) ) then  //do something end should become something like: rule "group 1" when  There are mutliple transactions with the same value for prodCat then  //do something end Thanks, Tim _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
