Hello,
I got a simple relation between two object :
@Entity
class Spot {
// ....
@OneToOne(targetEntity = Pics.class, cascade = CascadeType.ALL,
fetch = FetchType.LAZY)
private Pics pics;
// ...
}
I have to update this relation by setting a new "Pics" objet for an
already persisted Spot.
Example :
I persist a Spot object (with a Pics setted)
I retrieve this last Spot from the datastore, then change pics field
with a new Pics Object, and call persist again from the EntityManager.
(in order to update the datastore)
When I retrieve the Spot object, again from the datastore, the pics
field is still setter with the first Pics object, and not the new one.
So I'm a little bit confuse because the new relation isn't persisted !
Thanks to App Engine Test helper, I created a small test which show
this use case :

Where am I wrong ? My code is correct or I call the wrong method on
the entityManager ? or maybe my mapping is wrong ? (or I simply miss
something about JPA)
Thank you for your help :)
