Debug level Hibernate log excerpt:
Referencing the following figure, I'm trying to associate a hibernate component with another table in a many-to-many relationship. I get an error about WarningPreferences being unmapped when attemping to build my database. What's wrong?

According to this link (

The properties of a component may be of any Hibernate type (collections, many-to-one associations, other components, etc). Nested components should not be considered an exotic usage. Hibernate is intended to support a very fine-grained object model.
