Mapping exception using Stof/Gedmo Translation - php

Question

I'm migrating my Symfony 2.0 project to version 2.1rc1. After installing the stof/doctrine-extensions-bundle and the gedmo/doctrine-extensions and test my application I get the following error:
No identifier/primary key specified for Entity "Company\TestBundle\Entity\PageTranslation" sub class of "Gedmo\Translatable\Entity\MappedSuperclass\AbstractTranslation". Every Entity must have an identifier/primary key.
My config.yml looks like this:
# Doctrine Configuration
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
orm:
auto_generate_proxy_classes: %kernel.debug%
connection: default
auto_mapping: true
mappings:
gedmo_translatable:
type: annotation
prefix: Gedmo\Translatable\Entity
dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Translatable/Entity"
alias: GedmoTranslatable # this one is optional and will default to the name set for the mapping
is_bundle: false
gedmo_translator:
type: annotation
prefix: Gedmo\Translator\Entity
dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Translator/Entity"
alias: GedmoTranslator # this one is optional and will default to the name set for the mapping
is_bundle: false
stof_doctrine_extensions:
default_locale: en
translation_fallback: true
orm:
default:
translatable: true
sluggable: true
According to the documentation of StofDoctrineExtensionsBundle this should be fine. The only thing I'm not sure of is the auto_mapping: true option.
The only code I've changed in my project is in my CategoryTranslation class. I've replaced:
use Stof\DoctrineExtensionsBundle\Entity\AbstractTranslation;
by:
use Gedmo\Translatable\Entity\MappedSuperclass\AbstractTranslation;
Because the Stof-bundle doesn't have an AbstractTranslation class anymore.
Can someone tell me how I can fix this?

Answer 1

My PageTranslation entity before:
class PageTranslation extends AbstractTranslation
{
/**
* All required columns are mapped through inherited superclass
*/
}
My PageTranslation entity after generating the entities on the commandline:
class PageTranslation extends AbstractTranslation
{
/**
* All required columns are mapped through inherited superclass
*/
/**
* #var integer $id
*/
private $id;
/**
* #var string $locale
*/
private $locale;
.....etc....
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set locale
*
* #param string $locale
* #return PageTranslation
*/
public function setLocale($locale)
{
$this->locale = $locale;
return $this;
}
/**
* Get locale
*
* #return string
*/
public function getLocale()
{
return $this->locale;
}
..etc....
}

If you are using StofDoctrineExtensions you don't need gedmo/doctrine-extensions. Also isn't necessary to generate anything in PageTranslation
