Brian, Can you please provide one example for us to understand better the case?

class MyObject { private Integer used; private Integer notUsed; // public setters/getters... } rule "1" when MyObject(used == 1) then // do something end rule "2" when UnrelatedObject(data == 5) MyObject(notUsed == 2) then // do something else end Basically, I am trying to create JUnit test cases to test each of the rules functionality. So I would instantiate and object, set the required data to fire a rule, assert the object and fire all rules. So when setting MyObject.used = 1, then asserting that fact...it appears that rule 2 would complain that notUsed is null (even though I do not have an asserted fact where UnrelatedObject(data == 5). Does this make sense? I know this is sort of pseudo code thrown together quickly, but I think that explains what I was experiencing. If not, I can go back to get some of the actual code, but that would be much longer.
