I have a parent entity which has multiple one-to-one and one-to-many relationships with other entities. But when I call store on the session for the parent, the child entities don't get persisted at all. In this particular case, the entire obect graph is a set of entities that are created brand new, and the goal is to save the parent and all their associated children. :?

Do you have inverse set to true on the parent collection? If you do you'll need to persist the other objects yourself.

Have you enable cascading in your mapping ?
(eg. cascade="all-delete-orphan")

Thanks for your responses. I finally figured out what the problem was. The culprit was due to a one-to-one mapping on a primary key association. I am not able to get this one to one association to work, even after following the text book definition of defining the primary key on the child.



Both sides of the relationship have been defined using one-to-one association with the constrained="true" set on the child side of the association.
