OnPreIdUpdate()
Allow for "fake id's" to be forced upon related objects.
Declaration
protected virtual void OnPreIdUpdate()Remarks
In order to figure out which objects taking part of the nested save operation that actually needs to be saved, this method allows for "fake id's" to be forced upon related objects. Upon receiving the "fake id", the objects receiving such an id can determine if they need to be persisted (e.g. saved) to the database. However, the fake id's forced upon related objects must be set to correct id's in the OnIdUpdate method taking place later in the save operation.
