Following Tutorial 2: ArticlePage.php, causes a crash with:
"Fatal error: Call to a member function setConfig() on a non-object in C:\wamp\www\silverstripe\mysite\code\ArticlePage.php on line 12"

The code when adding the improving datefield instructions:

class ArticlePage extends Page {
static $db = array(
'Date' => 'Date',
'Author' => 'Text'

public function getCMSFields() {

$fields = parent::getCMSFields();

// JCo - Tutorial 2: Modifying Date field. Problem with the next line:
// $fields->addFieldToTab('Root.Main', $dateField = new DateField('Date','Article Date (for example: 31/07/2012)'), 'Content');
// JCo - circumventing the problem....>

$datefield = new DateField('Date','Article Date (for example: 31/07/2012)');
$datefield->setConfig('showcalendar', true);

// Tutorial 2 - SS 3.0.1 - Next line causes crash
// $dateField->setConfig('dateformat', 'dd-MM-YYYY');

$fields->addFieldToTab('Root.Main', $datefield, 'Content');
$fields->addFieldToTab('Root.Main', new TextField('Author','Author Name'), 'Content');

return $fields;

class ArticlePage_Controller extends Page_Controller {

What I'm doing wrong?
Kind regards, K=JohnC

Variables in PHP are case sensitive. You've defined $datefield, but are trying to call a method on $dateField.

I didn't catch that one. And of course, that explains the other line... :)

Kind regards,
