[symfony-users] Overwriting values in through class

[juro]

Hi,
I am using Doctrine for this project and have a problem with the
following scenario.

Article:
  actAs:
    Timestampable: ~
  columns:
    id:
      type: integer(11)
      primary: true
      autoincrement: true
    title: string(255)
  relations:
    Categories:
      class: Category
      local:  article_id
      foreign: category_id
      refClass: ArticleCategory
      foreignAlias: Categories

Category:
  actAs:
    Timestampable: ~
  columns:
    name:
      type: string(255)
      notnull:  true
    slug:
      type: string(255)
      notnull: true
  relations:
    Article:
      local:   category_id
      foreign: article_id
      refClass: ArticleCategory
      foreignAlias: Article

ArticleCategory:
  columns:
    article_id:
      type: integer(11)
      primary: true
    category_id:
      type: integer(11)
      primary: true
    rank:
      type: integer
      default: 0
  relations:
    Article:
      onDelete: CASCADE
    Category:
      onDelete: CASCADE

Now I have generated a custom form to assign the 'rank' field but
whenever I update an article, rank is set to 0. I want the rank to
stay what it is stored when saving an article. I am assuming that I
have to update this method:

  public function saveCategoriesList($con = null)
  {
    if (!$this->isValid())
    {
      throw $this->getErrorSchema();
    }

    if (!isset($this->widgetSchema['categories_list']))
    {
      // somebody has unset this widget
      return;
    }

    if (is_null($con))
    {
      $con = $this->getConnection();
    }

    $this->object->unlink('Categories', array());

    $values = $this->getValue('categories_list');
    if (is_array($values))
    {
      $this->object->link('Categories', $values);
    }
  }

Any ideas how I can handle the rank field?
