             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 5.1.1.FINAL

Exception executing predicate with binding variable and or predicate

When I execute this kind of rule :
(where field id from Object Entity is an Integer.)

rule "test"
salience 20
when
	(String() or Double())
	$entity:Entity()
	DroolsTest(entity.id == $entity.id )
then
	System.out.println( "it works !" );
end



I got this exception :

Exception in thread "main" org.drools.RuntimeDroolsException: Exception executing predicate entite.id == $entite.id

this rule Works :

rule "test"
salience 20
when
	$entity:Entity()
	DroolsTest(entity.id == $entity.id )
then
	System.out.println( "it works !" );
end
