Hello,

I'm testing NHibernate to see if it will fit our needs.

In our context, the edition of objects is complex and we need to perform some merge when concurent editing is happening (optimist locking will not fit).

In ADO.NET DataSet, the rows have an edition status (added, modified, deleted, ...), gives it any way to have this information on the objects loaded through NHibernate ? If this status is avaliable (or not), is that possible to have the original object value ? (it means the one which was loaded through NHibernat before any edition).

I've seen some remarks about cache, and cache level 2 but haven't found the way to use that.

Thanks for any help
Bye

NHibernate does not manage the entity state. This disadvantage, if one can call it that, comes as a cost to the flexibility NHibernate offers. Namely, it can map to any plain old class; no need for special inheritance from a particular class. The only real requirement is the entity class must have a parameterless default constructor; it can even be private, but it must be there. Since any class can be used as entities, you can implement any type of status management as you see fit.

Second level caches has nothing to do with object status etc.
