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,
