Hi.

I have a relationship (many-to-many) between "Tarefas" and "Ocorrencias". This generated the N-N table "TarefaOcorrencia".

When I do:

Tarefa t = new Tarefa();
TarefaOcorrencia to = new TarefaOcorrencia();
// load "to" with the values
t.Ocorrencias.Add(to);
t.Update();

I get this error:

SQL insert, update or delete failed (expected affected row count: 1, actual affected row count: 0). Possible causes: the row was modified or deleted by another user, or a trigger is reporting misleading row count.

I think it's not necessary to post all my hbm.xml files because I'm using composite-ids. So, i'd like to know if it's possible to use cascade-Update using composite-id.

Tks
