Symfony2 Doctrine2 Inheriting an Entity in another Bundle
===

Trying to create 2 bundles. One is a portal and the other is a training bundle. The thing that I'm having trouble grasping is how to create an entity in the portal bundle that inherits an entity in the training bundle (and overwrites the training bundles entity).

    PortalBundle
      Course Entity Extends TrainingBundle Course
        Add a Many to Many Relationship with another PortalBundle Entity
    

    TrainingBundle
      Course Entity
        One to Many Relationship with Lesson Entity

**Is this even possible?** I tried creating the TrainingBundle:Course Entity as a MappedSuperClass but this is not possible because the TrainingBundle:Course entity has a One to many relationship.

If I try to just extend the TrainingBundle:CourseEntity I get an error "The table with name 'Course' already exists.
