Kai Feng Zhang updated OPENJPA-1797:
------------------------------------
Attachment: PersonDb.java
EmailDb.java
ListFieldDb.java
This only happens when I want to persist the subclass entity. If it's a
no-superclass entity and has manytoone relation to person, then I can store all
its data into table.
> Can not persist subclass entity with its full data, if this subclass entity
> has ManyToOne to another entity

> Key: OPENJPA-1797
> URL: https://issues.apache.org/jira/browse/OPENJPA-1797
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Affects Versions: 2.0.1
> Reporter: Kai Feng Zhang
> Attachments: EmailDb.java, ListFieldDb.java, PersonDb.java
>
>
> A Person entity class, which has such emails field:
> @OneToMany(targetEntity = EmailDb.class, mappedBy = "person", cascade =
> CascadeType.ALL)
> protected List<ListField> emails = new ArrayList<ListField>();
> While Email entity is subclass of @MappedSuperclass ListFieldDb.
> Then I create email and add to person:
> EmailDb email = new EmailDb();
> email.setValue(targetAddress);
> email.setPrimary(false);
> email.setType("emailType");
> person.addEmail(emial);
> em.persist(person);
> But what I see from console about email table changes is: INSERT INTO email
> (oid, person_id) VALUES (?, ?), and other data lost, especially the map key
> 'person_id' to person table.
> Not sure if I am using something wrong? or this is a known issue?
> I pasted source code files for entity relationship reference. Thanks.
