Symfony 必须管理传递到选项字段的实体。Can'；t将项传递给数组字段

在尝试使用下面的操作打开表单时，我在Symfony 2中遇到以下错误

必须管理传递到选项字段的实体。也许会坚持下去 他们在实体管理器中？500内部服务器错误- 运行时异常

在提交表单之前，如何持久化依赖于另一个实体的实体，正确的方法是什么？ 我正在尝试使用以下方法存储传递到表单的项：

$imoved = new ItemMoved();
$imoved->setItem($Item);
$entity->setItems(array($imoved));

显示表单类型，处理
MovementNotification
实体的表单类型。此外，
MovementNotification
实体中的
$items
属性应设置为
ItemMoved
的
集合。好的，我添加了MovementNotification的表单类型，我也收到了错误“此表单不应包含额外字段。”在表单中。
$form=$This->createForm（$entity）；
更改为
