@OrderColumn, @OneToMany & null index column for collection

Question

I am trying to create parent child tables where the order is preserved. The example 7.8 from Hibernate documentation shows how to do this:

@Entity
public cl         


        

Answer 1

Moin,

the same problem occurs on hibernate.core 5.1.4 final. Using Set and HashSet on tag @OrderColumn (like Augustin said) fix the problem.
