I have a DO product:


class Product extends DataObject {

static $db = array(
   'name' => 'Varchar',
   'description' => 'HTMLText',
   'price' => 'Decimal(6,2)',
);

static $has_many = array(
   'Images' => 'MyImage'
);

public function getCMSFields_forPopup() {
   
   $images = new MultipleImageUploadField('Images', 'Images');
   $images->removeFolderSelection();
   $images->uploadFolder = 'Uploads/Produktbilder';
   
   return new FieldSet(
    new TextField('name', 'Produktbezeichnung'),
    new HtmlEditorField('description', 'Produktbeschreibung'),
    new TextField('price', 'Preis'),
    $images
   );
}

}

and a MyImage:


class MyImage extends File {

static $has_one = array (
   'Product' => 'Product'
);

}

I added Product to a tab with Dataobjectmanager:


$fields->addFieldToTab("Root.Content.Produkte", new DataObjectManager(
         $this,
         'Products',
         'Product',
         array(
          'name' => 'Produktbezeichnung',
          'description' => 'Produktbeschreibung',
          'price' => 'Preis'
         ),
         'getCMSFields_forPopup'
      ));

Now I can add Products, and also the Images to the products. But when I wan to edit the Product:


[Warning] array_flip() expects parameter 1 to be array, null given

1327          throw new Exception("Unknown $type component '$component' on class '$this->class'");
1328       }
1329       
1330       if($fieldPos = strpos($remoteClass, '.')) {
1331          return substr($remoteClass, $fieldPos + 1) . 'ID';
1332       }
1333       
1334       $remoteRelations = array_flip(Object::combined_static($remoteClass, 'has_one', 'DataObject'));
1335       
1336       // look for remote has_one joins on this class or any parent classes
1337       foreach(array_reverse(ClassInfo::ancestry($this)) as $class) {
1338          if(array_key_exists($class, $remoteRelations)) return $remoteRelations[$class] . 'ID';
1339       }
1340       

what could be wrong here?
