In this link there is a very basic example.
I have a class, its name is "dog" and it has a "name" property and a "childs" property. The "childs" property type is LINKLIST.
When a try to create a new dog object I crete a "childs" field but I don't know how to fill it.
Please point me to a more complete tutorial (actualy I search it with out success).
You can use the query for that:
insert into animal set name = 'dog', children = [<rid>]
where <rid>
is the record id of the child.
