Fill CCK fields

Hi all,

I'm facing few problems using Simpletest module.
I can't fill cck fields in a page node type.
The question is "How to do it?"
I've check subject about that : http://groups.drupal.org/node/26251 but I've not found answer.

My code :

<?php
// $Id: simpletest_example.test,v 1.1.2.4 2010/05/07 01:47:53 rfay Exp $

/**
 * Tests the SimpleTest Example module's content type.
 */
class SimpleTestPageTestCase extends DrupalWebTestCase {

  protected $privileged_user;

  public static function getInfo() {
    return array(
      'name' => 'SimpleTest Page',
      'description' => 'Ensure that the page content type provided functions properly.',
      'group' => 'SimpleTest',
    );
  }

  public function setUp() {
    parent::setUp(
      'node',
      'content',
      'fieldgroup',
      'optionwidget',
      'text',
      'number',
      'date_api',
      'date_timezone',
      'date',
      'date_popup',
      'text');
    // Create and log in our privileged user.
    $this->privileged_user = $this->drupalCreateUser( array('create page content'));
    $this->drupalLogin($this->privileged_user);
  }

  public function testPageCreate() {
    // Create node to edit.
  	$edit = array (
		  'title' => 'Test Fonctionnement Automator N2',
		  'field_page_footnote[0][value]' => $this->randomName(350),
		  'language' => 'nl-BE',
		  'field_generic_date_autopub[0][value][date]' => '16/12/2010',
		  'field_generic_date_autopub[0][value][time]' => '08:22',
		  'field_generic_date_autounpub[0][value][date]' => '30/12/2010',
		  'field_generic_date_autounpub[0][value][time]' => '17:22',
		);

    $this->drupalPost('node/add/page', $edit, t('Save'));
    $this->assertText(t('page @title has been created.', array('@title' => $edit['title'])));
  }

}

?>

Errors returned :
