---------------------------------
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}
