Even after setting $orm->field where field is a $_belongs_to alias, ORM does not save the value to database upon calling save(). It turned out that in __set() method, the 'if' block that handles $_belongs_to alias is missing $this->_changed, causing the alias to not been included in the insert/update statement to the database.

Sample:

$exercise = ORM::factory('exercise');
$exercise->title = 'Test2';
$exercise->user = ORM::factory('user', array('username'=>'user1'));
$exercise->save(); // this will only invoke "INSERT INTO `exercises` (`title`) VALUES ('Test2')" 

The model:

class Model_Exercise extends ORM {
    protected $_belongs_to = array( 
        'user' => array(),
    );
}

This can be fixed by adding the following line in ORM::__set() method

$this->_changed[$column] = $this->_belongs_to[$column]['foreign_key'];

elseif (isset($this->_belongs_to[$column]))
{
}
