JPA "org.apache.openjpa.persistence.ArgumentException" при удалении

Question

Имея объект сущности, как показано ниже, и когда я пытаюсь удалить объект родительской сущности, я получаю «org.apache.openjpa.persistence.ArgumentException», но am не знаете, в чем причина этого исключения.

Class Parent implements Serializable 
{ 
@ID 
@column(name="ParentKey") 
String parentKey; 

@manytomany 
@jointabel(name="Association_Parent_Child",joinColumns{ @joinColumn,@inversejoinColumn}) 
List<Child> Childs; 

} 

Below is the Child Entity 

Class Child implements Serializabe 
{ 
@ID 
@column(name="childKey") 
String childKey; 

@ManyToMany(mappedBy = "Childs", fetch = FetchType.EAGER) 
List<Parent> parents; 

@onetomany 
List<someOtherClassX> x; 

@onetomany 
List<SomeotherClassY> y; 
} 

В моем Уровне реализации DAO. У меня есть метод удаления

Parent DeletParent = new Parent(); 
DeletParent .setParentKey("ID"); 

Когда я вызываю entitymanager.remove ("DeletParent");

Любые предложения. В соответствии с исключением мы должны заполнить дочерний объект. Почему мы должны заполнять дочерний объект здесь?

Answer 1

Попробуйте это в родительском:

@ManyToMany(cascade = CascadeType.DETACH)
