Hi Joel,
The whole point of globals is that you don't need to assert them you just set them from the calling code, ie:
workingMemory.setGlobal("myList", arrayList);
You can then use myList in your consequence.
There is no way to use an asserted object in a consequence without binding it to a variable in one of the conditions.
cheers

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

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.

getResourceAsStream(ruleDrl) expects to find a drl file based on the location represented by "

It should be noted that the location should be accessible from the CLASSPATH. You could get a null pointer exception, if the location is not accessible from your CLASSPATH.
