Error messages with the container %s

[eluser]Unknown[/eluser]
If I set

Code:

$this->validation->set_message('required', " This is a test for %s!");

or just try to use error messages already set in validation_lang.php
I do not receive the expected result in the view file using printf or sprintf.

In the view file for

Code:

printf($error, "any string")

I get only " This is a test for !"
It behaves the same even in the controller.


Even for the codeigniter help example does not work
http://ellislab.com/codeigniter/user-gui...ation.html

Printing in view:

Code:

printf($this->validation->username_error, 'Username');

gives me back

Code:

'The field can not be the word "test"'

instead of

Code:

'The Username field can not be the word "test"'
