Whoops. I was to fast ;-)

It doesn't add it automatically (and it should not do that).

Simply add the property manually as done in the BlogExample:

class Tx_BlogExample_Domain_Model_Post extends 
Tx_Extbase_DomainObject_AbstractEntity {

	/**
	 * @var Tx_BlogExample_Domain_Model_Blog
	 * @lazy
	 */
	protected $blog;
  [...]

}

We are aware of the lack of proper documentation. At the T3BOARD10 I'll 
meet with Franz Ripfel to update the Quick Start Guide.
