我正在尝试为具有一对多关系的实体实现CRUD功能。 为简单起见，我最初实现了一个简单的客户端成员CRUD。如果一个客户有许多客户负责的成员。
Symfony2在我的实现中引发了以下错误。
Warning: spl_object_hash() expects parameter 1 to be object, array given in /home/evolve/public_html/bootstrap/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php line 1509Warning: spl_object_hash() expects parameter 1 to be object, array given in /home/evolve/public_html/bootstrap/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php line 1509

我明白我的clientController不完整，但不知道应该添加什么。我一直在努力工作，我很感激任何建议。
PS 这是我的第一篇文章，如果我在发布问题时应遵循的标准方面有任何改进，请告诉我。
