How to create new objects within this event?

I'm trying to save my audit log in different table, so I must create new object and save it but i doesn't work.

New objects are not persisted. :/

When hooking the SaveOrUpdate event it is important to also hook the Save and Update events as well, as these will be called for child entities depending on whether the child entities are new or not.

Good question, I am not sure what could cause that. I suggest you post a question on the nhibernate forum or nhibernate users mailing list.

hi,

nice work!
i have to implement a similar system and want to store a ModifyDate/ModifyUser in my Entities. For my Aggregate Root Entity (XObject) the ISaveOrUpdateEventListener is called and i can update the values the same way as your sample. Problem is, i also want to update the values ModifyUser/Date of a dependent Entity (XObjectVersion) and the Event is not called for the dependant entity.

I also tried to hook in the event 'IPreInsertEventListener' - this is called for both, my Aggregate root entity and my dependant entity BUT when i set values to the entity fields, they are not included in the SQL Statement that is sent to the database.

Has anybody any ideas how to solve this?
Maybe this is a bug because the sql statement is not sent to the database at this state of the process but changes to entity fields are not recogniced.

hi, thanks for your code.
Now the only thing i'm experiencing is that when i have a nested category structure (i have a parent Id), and i want to save one of my objects that has another item in it's collection of child members, it repeats twice (for the parent and the child), it's not saved to the database, and it's not giving any errors. I wanted to inspect the PerformSaveOrUpdate method but there is nothing in it, it's just a virtual method.

Nice stuff but it seems to modify all object before saving it to database.

I think we need to test if the object isDirty (or something else) ....

Do you have any ideas? ???
