[FLOW3-general] using ID in place of UUID

[Federico Bernardin]

Hi,
I'm having fun with typo3 flow, and I'd like to create a specific integer id in my entity. I have looked for documentation but it doesn't work.
I wrote this line:

/**
     * @var integer
     * @ORM\Column(name="id", type="integer")
     * @ORM|Id
     * @ORM|GeneratedValue
     */
    private $id;

Can you help me?

regards
Federico
