i need to save an object with different values of its primary key, but if i change properties and save it i'm getting an error.

so i need to : clone the oldest one, apply my changes to newest, delete the older and save the newer, it's the right way or not ?

thanks

in the future, please don't post with "Question" as your title. This gives potential helpers NO CLUE what you want and will likely gloss over it.

In order to do that you should detach the object from the session and then change the properties. When you attach the object again it will be a different identity.

I'm guessing also that GetHashCode() and Equals() might be returning identical values for your cases. Just a though.[/i]

which method should i use to detach it ? session.Evict() ?

and then how can i reattach i ?

thanks

session.Lock(obj) //i believe that will work.
