I am using decorators to decorate my entities. For example, I have a security decorator that hides values of entity properties not visible to the calling user. The decorators are put in place by special repositories decorating my common repositories. All this works as expected.
However, this approach leads to a problem when objects are persisted. For example, due to the mapping NHibernate expects an InventoryItem entity, but will receive a SecurityInventoryItem (the decorated entity). As a result an exception stating "Object does not match target type" is thrown. This is totally understandable, however mapping the common interface IInventoryItem is not an option either because the decorators would hide valuable information from NHibernate. Is there any hook in NHibernate that is called for each entity to be saved / updated that allows me to unwrap the entity (i.e transform entities before they are persisted)? I successfuly implemented the unwrapping for the save case with an IPreInsertEventListener, however I cannot find a way to do it for the update case.
