NHibernate 1.2.-beta2
SQL Server 2000 SP3

I have an EEvent Object that has some properties

EEvent.Id, EEvent.EventDateTime, EEVent.Device

In short terms, i was wondering if is possibile to get a "Collection of Collections" grouped by some criteria, eg. something like a Collection of collections grouped by Device or date range (EEVent properties)

IList Groups
---- IList -> EventGroup
[0] ---- Items -> EEVent - grouped by Device.Id = "49439"
[1] ---- Items -> EEvent - grouped by Device.Id = "33889" // etc...

I think NHibernate here can do only a part of the job, then further postprocessing is needed, just thinking about some creative solution to minimize the postprocessing work to get the needed result

Thanks in advance
