Do you need something like this, i.e. Moon doesn't refer back to Planet?
Entity Planet {
- @Set<Moon> moons
}
Entity Moon {
}
This will result in a uni-directional many association, but will be implemented in the database as many-to-many.
To implement it with an ordinary foreign key in the child table you have to add inverse
Entity Planet {
- @Set<Moon> moons inverse
}

Hi,
Is it possible to map a uni-directional one-to-many mapping? From looking at the documentation and template code, it looks like one has to mark the Reference as "inverse", which is a bi-directional mapping. I just want to have a simple uni-directional mapping.
Thanks!
