action_workflow_execute_transition

foreach ($choices as $sid => $name) {
          if (isset($flag)) {
            $new_state = $sid;
            $new_state_name = $name;
            break;
          }
          if ($sid == $current_state) {
            $flag = TRUE;
          }
        }

Please look carefully at the function. It is part of the function action_workflow_execute_transition.

This will only work (!) if the current_sid is always the first sid - but as we know - this is not guaranteed in 1.2

i changed it like this - but still - this is only a hack:

foreach ($choices as $sid => $name) {
        if ($sid == $current_state) {
            $flag = TRUE;
          }
        if (!$flag) {
            $new_state = $sid;
            $new_state_name = $name;
            break;
          }
         /* if ($sid == $current_state) {
            $flag = TRUE;
          }*/
        }
