Hi,
after struggling for several hours, i need to ask for help.
Following scenario.....
DB Table: Father
---------------------------
INT oid
....
DB Table: Childs
------------------------
INT oid
INT father_oid
...
Java Entity: Father
--------------------------
...
@OneToMany(cascade = CascadeType.PERSIST, mappedBy = "father")
private List<Child> childList;
Java Entity: Child
--------------------------
...
@ManyToOne(cascade = CascadeType.PERSIST)
@ElementForeignKey
@ElementJoinColumn(name="father_oid", referencedColumnName="oid")
protected Father father;
When i try to persist a Father, i am getting:
<openjpa-1.2.0-r422266:683325 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Field
"Father.childList" declares "Child.father" as its mapped-by field, but
this field is not a direct relation. at......
Ok, then i changed Child to:
Java Entity: Child
--------------------------
...
@ManyToOne(cascade = CascadeType.PERSIST)
@Column(name = "father_oid")
protected Father father;
When i now do persist a Father object, both DB records (Father and
Childs) are filled with records but the FK column in Child
(father_oid) is empty. So the FK relation is broken but it did persist
childs, which is somehow weird.
So whatever i do, i never get a fully persisted graph with correct FK
values.
Can anyone give me a hint what i am doing wrong here?
Thanks a lot.
