before an update it reloads twice

Hello,

I have a bidirectional association 1:1 between two classes: Customer and Account. Customer is the principal class but it is not the proprietary of the relationship.

Here you can see the partial mappings with annotations:

Code:

public class Account {

...

private Customer customer;

    @OneToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "customers_id")
    public Customer getCustomer() {
        return customer;
    }

    public void setCustomer(Customer customer) {
        this.customer = customer;
    }

...

}

Code:

public class Customer{

...

private Account account;

    @OneToOne(mappedBy = "customer", optional = true)
    public Account getAccount() {
        return account;
    }

    public void setAccount(Account account) {
        this.account = account;
    }

...

}

I'm using hibernate in a web application and everything works fine but there is a strange behaviour when I try to save the object.

Just before sending the update SQL to the DB, it refreshs the Customer object (one select) and the Account object (twice the same select).

I guess I'm missing something, can you help me?

Thanks in advance,

Pablo

Customer has a setCustomer()?
Account has a setAccount()?
Account as a private inner class of Customer?

confusing ...

The Customer class has an object Account with its correspondents get and set.
The Account class has an object Customer with its correspondents get and set.

There is no inner class, it is an object.
