Form Validation callback rules in controllers are viewable URLs

because I just came across the same issue again, here's an example:

if your private callback function is something like this:

[code]function _my_private_callback_function($variable) {}[code]

make sure that within this you set your custom error message as follows

[code]$this->form_validation->set_message('_my_private_callback_function', 'Error message text');[code]

(notice the underscore here also)
