Hi, we have ant old project with bad DB design, and now we are trying to upgrade to 2.1.2. I've outlined my problem on stackoverflow, so maybe i'll have more luck here :)
http://stackoverflow.com/questions/2858066/nhibernate-migration-from-1-0-2-0-to-2-1-2-and-many-to-one-save-problems If we take scenario that was provided on stackoverflow: //this Blog already exists in database BlogEntity blog = new BlogEntity(); blog.Id = Guid.Empty; blog.Reference = 1; //Reference is unique, so we can distinguish Blog by this field blog.Name = "My blog"; //this is new Post, that we are trying to insert PostEntity post = new PostEntity(); post.Id = Guid.NewGuid(); post.Name = "New post"; post.Reference = 1234; post.Blog = blog; session.Save(post); digging deeper, I've found that nhibernate 2.1.2 executes query to fetch BlogEntity: WARN: Unable to determine if BlogEntity with assigned identifier 00000000-0000-0000-0000-000000000000 is transient or detached; querying the database. Use explicit Save() or Update() in session to prevent this. Of course when querying, it gets null, and tries to insert PostEntity with BlogId having null. But as i see nhibernate 1.0.2.0 does not try to do the same. How can i force 2.1.2 act as 1.0.2.0 ? -- You received this message because you are subscribed to the Google Groups "nhusers" group.
