条令只保存最后的收藏品

我需要一些帮助，我用条令2研究ZF2。我有一个实体：带孩子的TaFoo：TaBar（ArrayCollection）。TaBar也有子类：ATypeBar（ArrayCollection）关联到TypeBar。我使用FieldSets添加多个TaBar，并在每个TaBar上添加多个ATypeBars。

但当我保存时：

• TaFoo是创建和保存
• TaBar也在创建和保存
• TaTypeBar只保存最后一个集合

我没有任何错误，但集合下的第一个永远不会保存

实体： TaFoo

我已经在$request->getPost中检查了数据是否正确，没有问题。保存TaFoo/TaBar/AtypeBar/TaTypeBar的所有数据都在中。但持久化不适用于TaTypeBar。
