私は Doctrine を初めて使用し、PersistentCollection を反復処理する際に問題が発生しています。ManyToMany 関係を使用していくつかの基本的なエンティティをセットアップしています。

 class File {

     /**
      * @ManyToMany(targetEntity="Row", mappedBy="file")
      **/
     protected $rows;

     public function __construct()
     {
         $this->rows = new ArrayCollection();
     }

     public function getRows()
     {
         return $this->rows; //this seems to return a persistantCollection
     } 
}

class Row {

    /**
     * @ManyToOne(targetEntity="File", inversedBy="rows")
     **/
    protected $file;
}

エラーログには以下が報告されていますが、何が報告されているのか理解できません。

問題は、関係が混乱していたことです。File.rows は OneToMany で、Row.file は ManyToOne です。
