Is it possible to use a collection attribute of one of my entities as the underlying data for an @DataModel in a bean?

For instance, say you have an entity

@Entity 
public class Library {
  @OneToMany
  private List<Book> books;
  public List<Book> getBooks() {return books;}
}

And a bean:

@Name("libraryManager")
public class LibraryManager {
  @In private Library library;

}

I wanted to use the list of books in the Library object as a source of data for an @DataModel. Is there any way to do this directly, or I must resort to having a List<Book> attribute in the bean and manually synchronize changes with the library object.
