[rules-users] Property Navigation

[Alessandro Lazarotti]

If  I've the simple classes:

public class ObjectBar{ public String name; gets/sets}

public class ObjectFoo{ public ObjectBar bar; gets/sets }

... and ObjectFoo this in WorkingMemory.

It's not possible navigate in objectFoo for make constraint in objectBar?
Example:

rule "Teste"
no-loop true
    when
        $foo: ObjectFoo(objectBar.name != "foobar")
    then
        System.out.println($foo);
end   

... but:
org.drools.RuntimeDroolsException: Exception executing predicate 
org.drools.base.mvel.MVELPredicateExpression at 18488ef
Caused by: org.mvel.CompileException: unable to resolve property: nome
Caused by: org.mvel.PropertyAccessException: unable to resolve property: 
nome
