As I have a problem Lords are a one-TION many.
I have added to my property hibernate mapping insertable = false and updatable = false property,
the table that makes a relationship of many composite pk has a foreign table references these fields, but particularly here is that my fields are not mandatory and the hibernate sql send me the database is not reflected the two columns. This occurs in all relationships with one to many and in many table are not mandatory and a table that is composed pk.
