Mario Fusco created DROOLS-42: --------------------------------- Summary: Equality comparison between classes of different types compiles but fails at runtime Key: DROOLS-42 URL: https://issues.jboss.org/browse/DROOLS-42 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Reporter: Mario Fusco Assignee: Mario Fusco Below is a fully self-contained DRL that compiles correctly but runs into a runtime error when the LHS of rule "match" is evaluated. The "culprit" is the test "this != $c", but one would expect simply a true result from the comparison. {code} declare Person name: String end declare Customer extends Person rating: int end declare Employee extends Person wage: int end rule initphone salience 100 when then insert( new Customer( "Joe", 100 ) ); insert( new Employee( "Paul", 2100 ) ); end rule match when $c: Customer() $e: Employee( this != $c ) then System.out.println( "c/e " + $c + " " + $e ); end {code} -- This message is automatically generated by JIRA.
