            //with ADO .Net this command is executed
        }
    }
}

This code seems that Ok, but after invocation of the method the object instanced doesn’t exist anymore and I need the ID's returned in this object passed by reference.

Look if I don't use ContextUtil (or [AutoComplete]) in the Person and Address classes this error doesn't appear.

Maybe that's because this post is from January 2004? .NET 2,0 didn't exist back then.

Please check the dates of the post you are replying to. I could be wrong, but generally I don't think there's much point reviving posts that are three or four years old....
