How is "not" supposed to work with insertLogical? Assume I have two different
rules whose conditions are mutually exclusive, like the following:
rule "Rule One"
when
not NegativeResult()
then
insertLogical(new ApplicantStatus("Approved"));
end
rule "Rule Two"
when
NegativeResult()
then
insertLogical(new ApplicantStatus("Denied"));
end
Assume that the above two rules are the only way an ApplicantStatus fact can be
inserted into working memory. I would expect, after all rules are run, that it
would be impossible for there to be one ApplicantStatus with "Approved" as its
reason, and another with "Denied" as its reason, in the working memory.
I would expect that, before any NegativeResult is inserted, that rule one could
run, and insert an ApplicantStatus fact with an "Approved" reason. Then, after
a NegativeResult is inserted, that rule two could run, and insert an
ApplicantStatus fact with a "Denied" reason. At this point I would expect that
the original ApplicantStatus fact, with an "Approved" reason, would be
retracted, since the conditions under which it was inserted are no longer true.
This is not what I am observing, however. I am finding ApplicantStatus facts
with both reasons in working memory at the end of the rules run. Should "not"
work as I expect with regard to inserting a fact via insertLogical()? Or is
this a known limitation, or simply the way it is designed to work?
Thanks,
