Exceptions are thrown when using reverse associations

[omaroman]

I have the following escenario:

Author <- Quote (quote has a reference to author)

@MappedSuperclass public class AuthorAbs extends Model {

// REVERSE ASSOCIATION

@OneToMany(mappedBy = "author", cascade = CascadeType.ALL, fetch = FetchType.LAZY) // name of the variable in the other object that references this object
public List<Quote> quotes = new ArrayList<Quote>(); // has_many :quotes

// FIELDS

@Required
public String first_name;

@Required
public String last_name;

}

@Entity @Table(name = "authors") @ElasticSearchable public class Author extends AuthorAbs { public int years;
}

@Entity @Table(name = "quotes") @ElasticSearchable public class Quote extends Model {

// Associations

@ManyToOne() // Optional, targetEntity for indicating where's the relationship
@JoinColumn(name = "author_id") // name of the FK field in this table
// --
@Required
public Author author;   // belongs_to_one :author

// Fields

@Required
public String quotation;

}

When updating an Author that has at least one Quote, throws the exception
