残念ながら、私は私の質問に答えなければなりません。
Twig.php (スリム エクストラ) でちょっとしたハックを行い、ObjectToArray という新しい関数を導入したところ、動作するようになりました。
function objectToArray( $object ) {
$array=array();
foreach($object as $member=>$data)
{
$array[$member]=$data;
}
return $array;
}
私のカスタムTwig.phpファイルは次のようになります

上記の変更なしで動作するはずです。
より良い解決策を見つけた場合は、お知らせください
