[karolski]

Witam,
Mam problem z uruchomineim widgetu relacji M:M w panelu admina, oto schma:

[PHP] pobierz, plaintext 
Product:
  actAs:
    Taggable: ~
    Timestampable: 
      created:
        name: created_at
        type: timestamp
        format: Y-m-d H:i
        expression: NOW()
        onInsert: true
      updated:
        disabled: true
  options:   { type: INNODB, collate: utf8_unicode_ci, charset: utf8 }
  columns:
    name:              { type: string(255), notnull: true, unique: true }
  relations:
    Packages:  { class: Package, local: product_id, foreign: package_id, refClass: PackageProduct  }
 
Package:
  actAs:
    Timestampable:
      created:
        disabled: true
      updated:
        disabled: true
  options:   { type: INNODB, collate: utf8_unicode_ci, charset: utf8 }
  columns:
    name:            { type: string(255) }
  relations:
    Products:  { class: Product, local: package_id, foreign: product_id, refClass: PackageProduct  }
 
PackageProduct:
  actAs:
    Timestampable:
      created:
        disabled: true
      updated:
        disabled: true
  options:   { type: INNODB, collate: utf8_unicode_ci, charset: utf8 }
  columns:
    package_id:        { type: integer, primary: true }
    product_id:        { type: integer, primary: true }
[PHP] pobierz, plaintext 

w formie modelu package mam:

[PHP] pobierz, plaintext 
class PackageForm extends BasePackageForm
{
  public function configure()
  {
     $this->widgetSchema['product_list']->setOption('renderer_class', 'sfWidgetFormSelectDoubleList');
 
     $this->widgetSchema['product_list']->setOption('renderer_options',
        array(
           'label_associated' => 'powiązane',
          'label_unassociated' => 'dostepne produkty',
        )
      );
 
  }
}
[PHP] pobierz, plaintext 

i dodaje product_list w generator.yml (modulu generowanego poprzez admin generator dla modelu Package), po czym jak proboje dodac nowy package dostaje blad:

[PHP] pobierz, plaintext 
Fatal error: Call to a member function setOption() on a non-object in C:\wamp\www\lib\form\doctrine\PackageForm.class.php on line 15
[PHP] pobierz, plaintext
