Save a model with a relation OneToMany

[Bouki]

Hi
I have models like this :

public class Person extends Model {
...
@OneToMany(orphanRemoval = true, mappedBy = "person")
@Cascade({ CascadeType.ALL })
public List<Contact> infos = new ArrayList<Contact>();
}

public class Contact extends Model {
...
@ManyToOne(optional = false)
public Person person;
}

And I have a method in my controller like this :

public static void savePerson(Person person) {
person.save();
renderJSON(person);
}

My issue is that when I try to save a person with savePerson() I have
this error (only if my list of Person isn't empty) :

PersistenceException occured : org.hibernate.HibernateException: A
collection with cascade="all-delete-orphan" was no longer referenced
by the owning entity instance: models.Person.infos

I don't understand the error message because it appears if the list
was previously empty or not.

Weird, I don't seem to be able to reproduce this problem. Which Play! version are you using?

I'm using 1.2.1

I'll describe more precisely the issue.

This is the original error I have on any insert :

java.lang.RuntimeException: java.util.concurrent.ExecutionException:
play.exceptions.JavaExecutionException:
org.hibernate.PropertyValueException: not-null property references a
null or transient value: models.Contact.person

I fixed it manually by overriding the method save from class Person
like :
for (Contact contact : this.infos) {
contact.person = this;
}
super.save();

Then this works partially, I have this error when infos is filled

PersistenceException occured : org.hibernate.HibernateException: A
collection with cascade="all-delete-orphan" was no longer referenced
by the owning entity instance: models.Person.infos

Can anyone help me to solve this strange issue ?

Do you want save contact when you call savePerson?

[Bouki]

yes
