Hi, I've noticed that the config file parser allows for un-named branch and failure routes (see failure_route_stm and branch_route_stm in cfg.y) The core cookbook says that these routes are only run when armed with t_on_failure/t_on_branch, and a quick test confirms that. Should default failure and branch routes be removed from cfg.y? Hugh -- Hugh Waite Principal Design Engineer Crocodile RCS Ltd.
