[rules-users] how do you select from a global List in decisiontable

[Gregory Mace]

Here is a simple example where 'otherPersonList' is a global java.util.List:

RuleTable Are friends having fun
CONDITION						CONDITION					ACTION
person: Person,  op: Person from otherPersonList	
person.getRelationShip(op)				op.getActivity()				System.out.println("$param");
FRIEND							PLAYING						Your friend is having fun
ENEMY							WORKING						Not your friend and not having fun

which produces the following drl output:

#From row number: 31
rule "Friends are having fun_31"
	
	when
		person: Person, op : Person from otherPersonList(person.getRelationShip(op) == "FRIEND", op.getActivity() == "PLAYING")
	then
		System.out.println("Your friend is having fun ");
end

#From row number: 32
rule "Friends are having fun_32"
	
	when
		person: Person, op : Person from otherPersonList(person.getRelationShip(op) == "ENEMY", op.getActivity() == "WORKING")
	then
		System.out.println("Not your friend and not having fun");
end

shouldn't the 'from' be after the statement like this:?

person: Person, op : Person(person.getRelationShip(op) == "ENEMY", op.getActivity() == "WORKING") from otherPersonList

Thx
