sf 2.6 A2LiX entityTranslation doesn't found

I just want to make a multilingual application site so I red and saw translatable and other bundle.

I use translatable and a2lix... so I read the doc but when I try to use a2lix, I get this error message :

Class c2c\AppBundle\Entity\PeriodTranslation does not exist 500 Internal Server Error - ReflectionException

I set my entityTranslation in a subfolder like so Entity>Translation>MyEntityTranslation

Is there a way to say to a2lix... that it should look inside my sub-folder ?

Thank you for your help.

Entity

namespace c2c\AppBundle\Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;
use Gedmo\Translatable\Translatable;


/**

 * @ORM\Table(name="Periods")
 * @ORM\Entity(repositoryClass="c2c\AppBundle\Entity\PeriodRepository")
 * @Gedmo\TranslationEntity(class="c2c\AppBundle\Entity\Translation\PeriodTranslation")
 */
class Period implements Translatable
...

Entity Translation

namespace c2c\AppBundle\Entity\Translation;

use Doctrine\ORM\Mapping as ORM;
use Gedmo\Translatable\Entity\MappedSuperclass\AbstractTranslation;

/**

/**

 */
class PeriodTranslation extends AbstractTranslation
{
    /**
     * All required columns are mapped through inherited superclass
     */
}

Solution

The error is thrown becous the newest version of a2lix is not compatible with the stable version of Gedmo

check this answer https://stackoverflow.com/a/22018321/2160958

If you want to use Gedmo strategy you will have to downgrade your "a2lix/translation-form-bundle" to "1.*@dev" if you want to use the newest version of "a2lix/translation-form-bundle" you will have to use wip2.4 Gedmo version, with is unstable yet.
