[rules-users] Rules error

Hi, I m trying to do this: GeneralList and RequiredList are my global lists 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 rule "populate list for A with general status" when $a : A() $list : ArrayList( size > 0 ) from collect( B( a.name == $a.name, status == "U" ) ) then generalList.addAll($list2); System.out.println("general list size " +generalList.size()); generalList.removeAll(requiredList); System.out.println("general list size " +generalList.size()); End But remove all does not seem to have any effect. Any idea why???? Plus if I do when $a : A() $list : ArrayList( size > 0 ) from collect( B( a.name == $a.name, status != "U" ) ) // "!=" it just ends up giving me all the values and not what status is Please help.
