Symfony 3 - Doctrine 2 - 在 oneToMany 关系上的 orderBy 不起作用

Question

我在两个实体之间有一个非常简单的oneToMany/manyToOne 关系：

一个Workflow拥有多个States：

MyBundle\Entity\Workflow:
  type: entity
  id:
    id:
      type: integer
      generator: {strategy: AUTO}
  oneToMany:
    states:
      targetEntity: MyBundle\Entity\State
      mappedBy: workflow
      orderBy:
        stateOrder: ASC
      cascade: [all]
      orphanRemoval: true
      fetch: EAGER
  ...

很多States拿着一个Workflow：

MyBundle\Entity\State:
  type: entity
  id:
    id:
      type: integer
      generator: {strategy: AUTO}
  manyToOne:
    workflow:
      targetEntity: MyBundle\Entity\Workflow
      inversedBy: states
      cascade: [persist, merge, refresh]
  ...
  fields:
    stateOrder:
      type: smallint

但是orderBy: ASC 和orderBy: DESC 都没有命令状态。我跑了php bin/console doctrine:schema:update --force --complete --dump-sql，在更改选项时清除了缓存并重新启动了apache。

我还尝试doctrines official way 添加orderBy 选项：orderBy: {'stateOrder': 'DESC'} / orderBy: {'stateOrder': 'ASC'} 得到相同的结果...

这是呈现表单时运行的查询：

SELECT 
  t0.id AS id_1, 
  t0.name AS name_2, 
  t0.project_id AS project_id_3, 
  t4.id AS id_5, 
  t4.stateOrder AS stateOrder_6, 
  t4.workflow_id AS workflow_id_7, 
  t8.id AS id_9, 
  t8.keyWord AS keyWord_10, 
  t8.action AS action_11, 
  t8.workflow_id AS workflow_id_12, 
  t8.from_id AS from_id_13, 
  t8.to_id AS to_id_14, 
  t0.initialState_id AS initialState_id_15 
FROM 
  workflow_Workflow t0 
  LEFT JOIN workflow_State t4 ON t4.workflow_id = t0.id 
  LEFT JOIN workflow_Transition t8 ON t8.workflow_id = t0.id 
WHERE 
  t0.id = '10';

所以 order by 不是查询的一部分...

任何建议为什么这不起作用？

众所周知，open issueorderBy 不能与 fetch: EAGER 结合使用。所以要么删除fetch: EAGER 或sorting the doctrine collection 解决问题。
