as you can see the result of the rule give me two facts with
java.lang.String as the partyid
==> f-2 (MAIN::party1ID (partyId <Java-Object:java.lang.String>))
==> f-3 (MAIN::party2ID (partyId <Java-Object:java.lang.String>))
I think that's the problem right there. These are of RU.JAVA_OBJECT
type instead of RU.STRING. Jess can work with String like this just
fine in many contexts, but they're not considered equal for pattern
matching. Generally, you want to write UserFunctions so that they
return Jess types whenever possible. Change the Value object
constructed by your UserFunction to explicitly use RU.STRING as the
type, and you should be all set.
