Sure, but that doesn't explain why: (1) The string is not truncated to match the limit. (2) The database ends up in an invalid state (e.g. I can't modify the object, I can't recreate the object, I can't modify the class..) Even if (1) is arguable, (2) shouldn't happen. Are you able to reproduce (2)? Thanks.
