The code is probably treating the DBI handle as any other blessed hash ref. It would store the contents of the hash and the class it was blessed into. Then it would 'reconstruct' the object by loading up a new hash and blessing it. The end result may look like a DBI handle, but it's not. As the error message says, it "has no magic" :) > I doubt from the error I'm seeing above that I can safely us it in a > production environment. Not a question of safely. It just won't work. Tim.
