Hi,

i am still working on an old problem. I have set up a gridfield for a many_many relation. Everything works fine, but if i want to "change relation status", the gridfield shows all items from page_mitarbeiter instead of mitarbeiter.

[url]http://stackoverflow.com/questions/19094863/multiple-rows-with-same-id-in-silverstripe-gridfield[/url]

   private static $many_many = array (
      'Mitarbeiter' => 'Mitarbeiter'
   );

   private static $many_many_extraFields = array(
      'Mitarbeiter' => array(
         'SortOrder' => "Int"
      )
   );

         $MitarbeiterFieldConfig = GridFieldConfig::create(200)->addComponents(
          new GridFieldToolbarHeader(),
          new GridFieldSortableHeader(),
          new GridFieldDataColumns(),
          new GridFieldDeleteAction('unlinkrelation'),
          new GridFieldSortableRows('SortOrder'),
          new GridFieldManyRelationHandler(), 'GridFieldPaginator'
          //new GridFieldPaginator(20)
         );

         $MitarbeiterField = new GridField("Mitarbeiter", "zuzuordnede Mitarbeiter", $this->Mitarbeiter(), $MitarbeiterFieldConfig);
         $fields->addFieldToTab('Root.Mitarbeiter', $MitarbeiterField);   

   public function Mitarbeiter() {
      $mitarbeiter = $this->getManyManyComponents('Mitarbeiter')->sort('SortOrder');
      return $mitarbeiter;
   }   

Can anybody help?

I don't know, what you mean with relation status. Did you mean from many_many to has_many?

Sorry, I know very little about the sortable gridfield module. At least I can´t see weird things in your code.
