Without lazy loading children are loaded immediately after load parent or with parent is you are using fetch=join. You can use "join fect" (higher loading) in a HQL/Criteria, even for multiple collections, but only if the entity have at most one <bag> (to know why think about the SQL). > > #2 - after the parent object loads, then all the children are loaded, > but if I need to populate some of those child collections with data, > for that specific parent object type, how do I determine that the > object coming through the Load Event Listener belongs to the patient > object I am trying to load data for (hoping there is a field I can key > off of). Probably you are delegating business matters to the DAL and probably because of that you are having this kind of "problems". > > More specifically, we want to inject specific data into our DTO after > it's read through NHibernate.
