[Lift] Re: Where did Mapper's MappedManyToMany go?
Since MappedOneToMany does not extend MappedField, in order for the entity to
manage its MappedOneToMany's it must extend ManyToMany. This allows saves and
deletes to be propogated, for example. When you add and remove elements from
the MappedManyToMany, those changes don't happen in the database until the
MappedManyToMany is saved. It's saved automatically when you save the mapper.
Also, when you delete the mapper it will delete the join table record. **Thus
it is very important that both sides of the many-to-many relationship have
ManyToMany and MappedManyToMany**, so that if you delete from either side the
join table will retain its integrity, as I have recently come to realize.
