Answer 1

From the docs you need to provide a key field to the dataprovider (similar to the issue you had in your previous posting).

Example:

$query = new Query;
$provider = new ArrayDataProvider([
    'key' => 'id' //make this unique identifier of your models.
    'allModels' => $query->from('post')->all(),
    'pagination' => [
        'pageSize' => 10,
    ],
]);

So in your case you'll probabaly need to add an id field to each set in $retval and do this:

  $dataprovider = new ArrayDataProvider([
  'key' => 'id', //or whatever you id actually is of these models.
  'allModels' => $retVal,
   'pagination' => array('pageSize' => 20),

  ]);

  return $dataprovider;
}
