set_value not working?

[quote author="Henrique Luz" date="1309545631"]The error occurs because you're validating the data before sending them to the view for the controller.[/quote]

Why should validating the data affect the data? The order of the functions in index() that I have used matches the demo at http://ellislab.com/codeigniter/user-gui...ation.html

[quote author="Henrique Luz" date="1309545631"]Then the email field is always blank, and thus, the method form_validation->run always returns false.[/quote]

form_validation->run does not always return false, it only returns false when the email is invalid, if it is valid then it returns true.
