Extending OrderCore problems. Class 'Order' not found...

[contentengineer]

We are experiencing some issues (we believe) with the class autoloader.

 

We have overridden the OrderCore class using the following definition:

<?php
/* ...
 * ...
*/

//Workaround
Order::$definition['fields']['customerref'] = array('type' => ObjectModel::TYPE_STRING,'validate' => 'isString', 'size' => 30);

class Order extends OrderCore
{
    public $customerref;

    public function __construct($id_order = null, $id_lang = null)
    {
        parent::__construct($id_order, $id_lang);
    }

}

After a period of time we then get the dreaded "white screen" in AdminOrders and front office screens. Looking at php_errors.log it is reporting:

[14-Oct-2014 15:12:35] PHP Fatal error:  Class 'Order' not found in /var/www/html/override/classes/order/Order.php on line 
[14-Oct-2014 15:12:41] PHP Fatal error:  Class 'Order' not found in /var/www/html/override/classes/order/Order.php on line 
[14-Oct-2014 15:12:57] PHP Fatal error:  Class 'Order' not found in /var/www/html/override/classes/order/Order.php on line

Can anybody shed any light?  Should there be an include_once to reference OrderCore.php?  Should we just be overriding  getFields() instead?

what line is it complaining about?

[contentengineer]

It would appear to be complaining about this line:

Order::$definition['fields']['customerref] = array('type' => ObjectModel::TYPE_STRING,'validate' => 'isString', 'size' => 30);

I have seen alternative approaches such as:

class Order extends OrderCore
{
     public $customerref;
     public function getFields()
     {
         $fields = parent::getFields();
         $fields['customerref'] = pSQL($this->customerref);
         return $fields;
     }
}

But this doesn't include the validation...?
