How do i refer from the code P_idproducto,the property idproducto throws me an excpetion and in the key tag i cannot insert the name property.

Thanks.

I've never try with 'key' column, but the following should work

<property name="IdProducto" column="P_IdProducto" type="int" update="false" insert="false"/>

Always returns zero ,any idea?.

getter / setter broken

What do you mean by "getter / setter broken".
The getters and setter are correct, ve already check them.
I need the primary key for using it in the following sentence:
losSuplementos = GuiSGP.session.find("from Suplemento where F_IdProducto ="+ idProducto
+ " and A_Habilitado =" + 1 + " and A_BajaLogica =" + 0);

Where id producto is the primary key ,Does exist a alternative way to do this?.

Thanks

Eh! the pk is mapped in the super class, so use it.
