Hi, How can I depict global lists in my business rules? For instance: rule "populate list for A with required status" when $a : A() $list : ArrayList( size > 0 ) from collect( B( a.name == $a.name, status == "P" ) ) then requiredList.addAll($list); end I want to depict my $list : ArrayList( size > 0 ) from collect( B( a.name == $a.name, status == "P" ) ) with help of business rules. Any idea how???
