Hi, I've been trying to implement kind of a "one-to-one" relationship between Person and User classes.
If I choose to have a relationshionship (there's a bug there in the new property wizard, even though you choose "one other object" as the relationship type, cardinality in the second class is written as "many", I had to correct it to "one" by hand); although not every person is a user, I cannot set the User property of a Person to nothing, %Save method generates an error. (that's normal if one-to-one relationship forces you to have a User for every Person and vice versa. Is this the case?) If I choose to have plain object references in each class, then I have to implement the relationship that I want to have manually, i.e. while saving an object, setting the corresponding property in the other class. (I want to have a User property in the Person class and a Person property in the User class as I'll need to get the other object's properties frequently) Of course I can only have a User property in the Person class, then everytime I need to find the Person properties of a User, I need to do a query. (I know that I can set it up as a calculated property)... But I thought I could implement it with a relationship.... Any hints? Regards, Teoman
