I think you'd have to use predicate expressions:
when
Company($s : supervisor -> ($s.getAge() < 25)) || Company($s : supervisor
-> ($s.getAge() > 67))
then ...
"$s : supervisor" binds the supervisor bean property of Company to the
variable $s, which you then use in the -> () construct, where you can use
arbitrary java expressions. I think this is the only way to access nested
bean properties in 3.0.

How can I write a rule like this if an object inherits methods from a
super class?
I have a class hierarchy like this: A Company object and a Person
object both inherits methods from an abstract parent object.
And the Company object has a getSupervisor() method which returns a
Person object.
If I want to write a rule for the to check the age of the Supervisor
when only the Company object is in the working memory.
Is this the way to go??
rule "age"
when
Company(Person(age< 25)) or Company(Person(age> 67))
then
System.out.println("The supervisor is younger than 25 or older
than 67 years");
end
