Hi,
I have been having some dificulties on how to configure and use the cascade tags when mapping one-to-many relationships.
In the case I am working on right now, I have one entity called LoteFinanceiro which has 2 one-to-many relationships, one with Cheque and another one with Dinheiro. You will be able to see the code in the mappings below.
I have been trying to use cascade="all", but when I delete in memory either one or several elements from one of these relationships, and try to update the main entity "LoteFinanceiro", it doesn't return any error, and does not make any changes in the database either. It is importante to remind that I am loading everything in one session and doing the update in another session.
So, I wonder if I am using the right tags for cascade.
Here follows what I really want to do:

1) When I delete de Main Entity "LoteFinanceiro", I want all the child elements from those one-to-many relations to be also deleted.
2) When I delete any child element from the relationships and try to update the main Entity, it has to be also deleted from the database.

Does anyone know how to do this?

Hello David,
I had already tried to use this tag, but it is not working quite as how I described. It is returning all kind of key errors when I try to update the main Entity LoteFinanceiro.
To achieve that behavior that I described are the mappings the child entities "Dinheiro" and "Cheque" right? It seems like every little change I make in the mappings I get different behavior and errors, and I have not reached exactaly what I want......

Could you could you give some more help one this David?
Thanks a lot in advance!
