After asserrting the following objects and performing the rule I get the error
shown

        PersonSummary personSummary = new PersonSummary();
        personSummary.setPrId(new Long(217));
        personSummary.setCmpntCd(new Character('R'));

        PersonSummary personSummary2 = new PersonSummary();
        personSummary2.setPrId(new Long(217));
        personSummary2.setCmpntCd(new Character('G'));

##################################

rule "Duplicate Projection for same processing date by another component"
        when
                $j : PersonSummary($prId : prId, $cmpntCd : cmpntCd)
                exists PersonSummary(this != $j, cmpntCd == $cmpntCd)
        then
                System.out.println("Error Found in rule Duplicate Component
Code");
end

If I change the exists rule to:

    exists PersonSummary(this != $j, cmpntCd == 'A')

it works fine.

Is there something I have to do to compare two char objects.

Thanks
