i need some help with Symfony and Doctrine forms.

What i want is to add a choice widget to a form, and load that choice widget with data from the db.

I have this in Survey.class.php:

```
$this->widgetSchema['service'] = new sfWidgetFormChoice(array(
  'choices'  => TService::getServiceTypes(),
  'multiple' => true,
  'expanded' => false));

```

And this is TService.class.php

```
class TService extends BaseTService
{
  static public function getServiceTypes()
  {
    return Doctrine::getTable("TService")
       ->createQuery()
       ->select('description')
       ->execute();
  }
}

```

What i have got is a select with 2 choices, and that's good, but the options are '1' and '2', instead of the service's descriptions.

Sugestions?

Thank you guys
