Jira issue originally created by user rfink:

When having a OneToOne mapping that has a primary key that is the same as the foreign key, using the @Id attribute does not carry over when generating entities.

Example code:

class User
{
    /**
     * @Id @Column(type="integer", nullable=false, columnDefinition="INT UNSIGNED NOT NULL AUTO_INCREMENT")
     * @GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @OneToOne(targetEntity="User_ExtraAttrs", cascade={"persist","remove","detach","merge","refresh"}, mappedBy="User")
     * @JoinColumn(name="id", referencedColumnName="id")
     */
    private $UserAttrs;
}

class User_ExtraAttrs
{
    /**
     * @OneToOne(targetEntity="User", cascade={"all"}, inversedBy="UserAttrs")
     * @Id
     * @JoinColumn(name="VehicleID", referencedColumnName="VehicleID")
     */
    private $User;
}

When running "doctrine orm:generate-entities --regenerate-entities=1 --generate-annotations=1", the @Id in User_ExtraAttrs does not carry over. It must be manually inserted.
