Hello everyone !

I have a class Commande extending ModelAdmin.
In Commande exists a nested DataObject called NumeroColis (1 field : 'Numero'). I'm using the wonderful DOManager to handle it and it's perfect.


When clicking the "Search" button, to show all the existing Commandes, I'd like to add a column called Numeros and for each Commande, show a list of the recorded NumeroColis.

This is what I did in Commande.php :

public function getListeNumeros() {
      $rawlist = DataObject::get('NumeroColis','CommandeID = '.$this->ID);
      $nums = $rawlist->column('Numero');
      $liste = implode(', ', $nums);
      if (isset($liste)) {
         return $liste;
      } else {
         return "Pas de colis";

static $summary_fields = array(
'ListeNumeros' => 'Numéros',

I get a Internal Server Error when clicking the Search button... and I spent a lot of time on this, so I decided to ask the great SStripe international community ! Anyone ?

Thanks to the messages answering my tweet, I got a little further in my search :



instead of

return $liste;

actually shows me the list of the Colis for my first Commande.

The Firebug Console is not helping, for it just says NetworkError : Internal Error 500 in mysite/admin/.../SearchForm

Maybe there's something to reset between two iterations ?

Update : Enabling error logging in htaccess brought me this information
(thanks simon !)

Fatal error: Call to a member function column() on a non-object
