Sure.  Here is one example (though I think it may have an
existential/universal not error as mentioned in another post):

rule "6040 Pass CA Fees"
        when
                #conditions
                $status : ValidationPassFailStatus()
                exists ValidationControl(validationNo == 6040)
                CiLines($ciNo : ciNo, $ciLineNo : ciLineNo,     $countryOrigin :
countryOrigin)
                Country(country == $countryOrigin, canadianProvince != "",
canadianProvince != "N")
                (CiLineFees(amtFee == 0, ciNo == $ciNo, ciLineNo == $ciLineNo)
                or not CiLineFees(ciNo == $ciNo, ciLineNo == $ciLineNo))
        then
                #actions
                 System.out.println("6040 Pass CA Fees");
                $status.passSq(6040);
end

I have tried this with and without the parenthesis for explicitness.  It
errors out when inserting facts for the rule:

java.lang.ClassCastException:
com.kewill.icustoms.customs.rules.model.ValidationPassFailStatusShadowProxy
        at

        at org.drools.reteoo.JoinNode.assertTuple(JoinNode.java:111)
        ...

However, if I break this into two separate rules, it behaves as expected
(with the possible existensial/universal logic problem I mention above).

rule "6040 Pass CA Fees"
        when
                #conditions
                $status : ValidationPassFailStatus()
                exists ValidationControl(validationNo == 6040)
                CiLines($ciNo : ciNo, $ciLineNo : ciLineNo,     $countryOrigin :
countryOrigin)
                Country(country == $countryOrigin, canadianProvince != "",
canadianProvince != "N")
                CiLineFees(amtFee == 0, ciNo == $ciNo, ciLineNo == $ciLineNo)
        then
                #actions
                System.out.println("6040 Pass CA Fees");
                $status.passSq(6040);
end

rule "6040 Pass CA No Fees"
        when
                #conditions
                $status : ValidationPassFailStatus()
                exists ValidationControl(validationNo == 6040)
                CiLines($ciNo : ciNo, $ciLineNo : ciLineNo,     $countryOrigin :
countryOrigin)
                Country(country == $countryOrigin, canadianProvince != "",
canadianProvince != "N")
                not CiLineFees(ciNo == $ciNo, ciLineNo == $ciLineNo)
        then
                #actions
                System.out.println("6040 Pass CA No Fees");
                $status.passSq(6040);
end
