How to map domain class with two instances of another domain class

I have two domain class as shown below. The top level class Client contains three references to Address class. It is a kind of 1..3 relationship. I want the Address objects to be saved by cascading when I save Client. What is the correct way to map such a relationship?

class Client {

    Address primaryAddress
    Address billingAddress
    Address shippingAddress

    static hasOne = [primaryAddress: Address, billingAddress: Address, shippingAddress: Address]

}


class Address {

    String addressLine1
    String addressLine2
    String addressLine3

}

hasOne maps the reference FROM the child to the parent (docs). So in your case, that would means each Address would store a reference to a Client, rather than an Address storing three references to Clients. From the sound of your question, that is not what you want, so you can just remove the whole hasOne mapping and stick with simple references.
