Hi all,

i have two tables joined by a foreign key.The relation between them are 1:n so many rows from child are from one Parent. I want that Child objects inherit foreign key from parent to all Primary key objects that owns. When I try to insert a new Parent with new childs gives me a key violation error. I think problems could be:

- It tries to insert first of all Child objects.

- Parent Foreign Key doesn´t have same value as Child Primary key.

What's wrong?. Here are my source code:


tIncidencias.hbm.xml (Parent)
