Hello, we're developing on SCA Kilimanjaro and have a question regarding custom field accessibilty. We have added custom fields that hold image urls to Item and we're not able to see these fields, or any custom fields, when looking at the item object in Item.KeyMapping in the Item module, specifically the _thumbnail property:

,  _thumbnail: function (item)
  {
   var item_images_detail = item.get('itemimages_detail') || {};

   // If you generate a thumbnail position in the itemimages_detail it will be used
   if (item_images_detail.thumbnail)
   {
     if (_.isArray(item_images_detail.thumbnail.urls) && item_images_detail.thumbnail.urls.length)
     {
      return item_images_detail.thumbnail.urls[0];
     }

     return item_images_detail.thumbnail;
   }
				
   ...
  }
