handleRequest（）がスワップした後のフォームコレクションデータ

Question

私はsymfony tutorialによってフォームのコレクションを埋め込みました。既存のエンティティの削除を除き、すべてが機能します。

初期データ：

+----+-------+ 
| id | value | 
+----+-------+ 
| 1 | a  | 
+----+-------+ 
| 2 | b  | 
+----+-------+ 
| 3 | c  | 
+----+-------+ 

その後収集フォームで私はa値のフォームを削除します。 （）

+----+-------+ 
| id | value | 
+----+-------+ 
| 1 | b  | 
+----+-------+ 
| 2 | c  | 
+----+-------+ 

はのhandleRequestのように見えるだけで、配列のコレクション値をオーバーライドして、すべての差分を削除しています：提出とのhandleRequest（）した後、データはなりました。期待される結果は次のようになります。

+----+-------+ 
| id | value | 
+----+-------+ 
| 2 | b  | 
+----+-------+ 
| 3 | c  | 
+----+-------+ 

そうですが、なぜでしょうか？
