Symfony2 Entity findAll() - symfony

Question

I have database table with 7 rows, I'am trying to fetch those rows with findAll function
$machine_current_counter_repo = $this->getDoctrine()->getRepository('DummyMonitorBundle:MachineCurrentCounter');
$counters = $machine_current_counter_repo->findAll();
The result is 7 rows, but all rows contain data from the first row.
Here is database table entity.
And table structure:
`machine_current_counter` (
`machine_id` tinyint(3) unsigned NOT NULL,
`counter_value` int(10) unsigned NOT NULL,
`time_stamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`machine_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
What could cause this problem?
Ps. Entity is generated from database so by default first column setup was this (not sure why type was "boolean", but I changes it to integer, still that didn't solved the problem):
/**
* #var boolean
*
* #ORM\Column(name="machine_id", type="boolean")
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $machineId;

Answer 1

#ORM\Id means values of this field MUST be unique. With the boolean type they can be unique only in 2 or less row (because boolean has only 2 values - 0 and 1).
I think you have logical mistake, and must simply change type of field to integer. Like that:
/**
* #var integer
*
* #ORM\Column(name="machine_id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $machineId;
Then update your schema by ./app/console doctrine:schema:update then recreate data into table.
