             Summary: Binding makes parser accept non-boolean constraint
                 Key: DROOLS-43
                 URL: https://issues.jboss.org/browse/DROOLS-43
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Mario Fusco
            Assignee: Mario Fusco


Below is a self-contained DRL which should not compile because the sum isn't a boolean expression. (Note that omitting "$x:" results in the correct diagnostic "predicate ... must be a boolean".)

{code}
declare Foo
  a: double
  b: double
end

rule what
when
    $c: Foo( $x: a + b )
then
    System.out.println( "foo: " + $c );
end
{code}
