Re: Fw: [rules-users] rules questions...

ok..after playing a while with this global thing...i found out that global variables cant be asserted... any other idea of how to use an asserted arrayList on the consequence without writing it on the conditions?

Hi Joel, I think you should rather use a global for the ArrayList: global java.util.List myList rule "cancel_menu" when MegaTransferObject(other_EffectiveOrderTypeDsl != null, other_EffectiveOrderTypeDsl == Constants.NEW_OPEN_ORDER_TYPE) not MegaTransferObject(orders_FkOrderStatusId != null, orders_FkOrderStatusId == Constants.PENDING_TO_BE_SUBMITTED_ORDER_STATUS) then myList.add(new String[]{Constants.SERVICE_ASSURANCE_TREE_MENU_DSL, Constants.SERVICE_ASSURANCE_MENU_CANCEL}); end btw - you don't need to put "and" at the end of each constraint. cheers Steve On 1/7/07, Joel G.
