symfony 2 many-to-many relationship - symfony

Question

I'm trying to realize a many-to-many relationship between two tables.
this is my configuration:
Mailer\EmpfaengerBundle\Entity\Empfaenger:
type: entity
table: empfaenger
id:
id:
type: integer
generator: { strategy: AUTO }
fields:
vorname:
type: string
length: 255
nullable: true
nachname:
type: string
length: 255
nullable: true
created_by:
type: integer
updated_by:
type: integer
manyToMany:
verteiler:
targetEntity: Verteiler
mappedBy: empfaenger
Mailer\EmpfaengerBundle\Entity\Verteiler:
type: entity
table: verteiler
id:
id:
type: integer
generator: { strategy: AUTO }
fields:
name:
type: string
length: 255
nullable: true
created_by:
type: integer
updated_by:
type: integer
manyToMany:
empfaenger:
targetEntity: Empfaenger
inversedBy: verteiler
joinTable:
name: verteiler_sys
joinColumns:
verteiler_id:
referencedColumnName: id
inverseJoinColumns:
empfaenger_id:
referencedColumnName: id
Now when I try to edit an entry, it works in the "verteiler" table, but not in the empfaenger table.
The form is shown in the "empfaenger" edit page and the entries are highlightet, but when i change ohne, it won't save the changes.
I tried various different configurations according to the doctrine documentation but always get the same result :-(
both entities have exactly the same structure:
/**
* Add empfaenger
*
* #param \Mailer\EmpfaengerBundle\Entity\Empfaenger $empfaenger
* #return Verteiler
*/
public function addEmpfaenger(\Mailer\EmpfaengerBundle\Entity\Empfaenger $empfaenger)
{
$this->empfaenger[] = $empfaenger;
return $this;
}
/**
* Remove empfaenger
*
* #param \Mailer\EmpfaengerBundle\Entity\Empfaenger $empfaenger
*/
public function removeEmpfaenger(\Mailer\EmpfaengerBundle\Entity\Empfaenger $empfaenger)
{
$this->empfaenger->removeElement($empfaenger);
}
/**
* Get empfaenger
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getEmpfaenger()
{
return $this->empfaenger;
}
and help would be appreciated.
