<<You may not change the reference to a collection with cascade="all-delete-orphan">>
That would be the problem.
Now you please tell me the solution.
I checked the code to assure that in no place i'm changing the reference to the collections got by recurso.getOpciones()

Hibernate version:
2.1

Recurso.hbm.xml:

the method does HibernateUtil.getSession, beginTransaction, and commitTransaction in the parent class
