One-to-many mapping inside component mapping creates a many-to-many table

Description

I have a bag one-to-many collection inside of a component.

This collection is correctly mapped by hibernate, but envers creates a many-to-many link table next to the one-to-many table.

When I move the collection up to the entity class instead of the component, the many-to-many link table is not created.

Why is the link table created when the collection is inside of a component object?
The link table should not be necessary, as it is not necessary when the collection is in the entity. The component mapping should make no difference right?

Your issue is not related to having a component or not. If the collection is bidirectional, normally you would map the collection with "inverse=true". If you do, no joined table will be created for the audited collection.

I'm sorry, yes I mean nhibernate, not hibernate. I work in both Java and .Net these days, but in this case, it is the .Net version.
Sorry for the confusion.

The attributes are custom indeed, but I thought it would provide a mapping example.
I forgot to mention in the example that PhoneNumber has a many-to-one relation back to Person.
Therefore it is bi-directional.

Again, when I place the PhoneNumber list in the Person Class, the link table is not created, but when put the list in the ContactInformation (mapped as a component) class, the link table is created.

Here is a sample nhibernate mapping:

You write hibernate but I guess we're talking nhibernate (.net) here and not Java version - right?

Don't know what the attributes you have in your snippet means but... In a unidirectional one-to-many relationship, a link table will be created for the audited entities.

If you think you have encountered a bug, please include minimal mapping to reproduce the issue here (or even better - create a pull request).
If you have user related questions, post a question on SO or nhibernate user mailing list.
