Here are my mapping files:


<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="SGP.Business.Financeiro.MoedasBsn,SGP.Business" table="MOEDAS" dynamic-update="true">

<id name="codigo" column="CODIGO" type="Int32" unsaved-value="0">
<generator class="increment"/> <!-- (increment, identity, sequence, assigned, etc.) -->
</id>
<property column="DESCRICAO" type="String" name="descricao" not-null="true" length="50" />
<property column="SIMBOLO" type="String" name="simbolo" not-null="true" length="3" />

<bag name="valoresMoedas" inverse="true" cascade="all-delete-orphan">
<key column="CODIGOMOEDA" />
<one-to-many class="SGP.Business.Financeiro.ValoresMoedasBsn,SGP.Business" />
</bag>

</class>
</hibernate-mapping>


<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="SGP.Business.Financeiro.ValoresMoedasBsn,SGP.Business" table="VALORESMOEDAS">

<id name="codigo" column="CODIGO" type="Int32" unsaved-value="0">
<generator class="increment"/> <!-- (increment, identity, sequence, assigned, etc.) -->
</id>

<many-to-one name="moeda" column="CODIGOMOEDA" class="SGP.Business.Financeiro.MoedasBsn,SGP.Business" cascade = "all" />

<property column="DATAREFERENCIA" type="DateTime" name="dataReferencia" not-null="true" />
<property column="VALOR" type="Int32" name="valor" not-null="true" />

</class>
</hibernate-mapping>


The problem is that when I try to update a parent (Moeda), by deleting one of its soon (ValoresMoedas) and then calling saveOrUpdateCopy(Moeda), the parent(Moeda) is also deleted. I load the object Moeda in one Session and persist it in another one, that is why I use saveOrUpdateCopy(object).

Does anyone have a clue?

Thanks!

I think the problem is the cascade = "all" here. Depending on the way you want to delete ValoresMoedasBsn instances you'd better use cascade="none" or "save-update".

Hey!

I was making so many changes to test it that I even forgot that cascade there! Lol

I just removed the property and it worked perfectly.

Thank you very much!!!!! I was trying to make it work for a long time!
