Doctrine2.3 and OneToOne cascade persist doesn't seem to work

Question

I have two entites (User and UserPreferences) that I want to map OneToOne unidirectional.

The code looks something like this:

/**
 * @ORM\\Table(\"us         


        

Answer 1

Bug was with

 * @ORM\Column(name="user_preferences_id", type="integer")

Your code should contain

 * @ORM\JoinColumn(name="user_preferences_id", referencedColumnName="id")

instead of this.
