Re: [eclipselink-users] none of the @OneToMany fields are being persisted in an @Embeddable class
|
Can you include the code you use to persist the object, and the log on finest
of the transaction.
Do any errors or warnings occur on startup?
It is odd to have a OneToMany in an Embeddable as they have no id, and note
that the embeddable is not mapping the ID column that is being used in the
join.
If you move the OneToMany to the parent, or change it to use a JoinTable
instead of a JoinColumn does it work?
