Routing issue - Pagination not working properly

[eluser]Mauricio de Abreu Antunes[/eluser]
Hello!

I have a controller here:
http://localhost/percutz/news(page 1)
http://localhost/percutz/news/1 (page 1)
http://localhost/percutz/news/2 (page 2)

Controller executes database method from model and returns a result to $data['news'].

No problem at there, but when i go for http://localhost/percutz/news/1 , i have a problem with

Code:

echo $this->pagination;

http://localhost/percutz/news
[1] 2 >
http://localhost/percutz/news/2
1 [2] >

Not showing Last and First and my $config array has $config['first_link'] = 'First New';
and < (previous page).

When i go for http://localhost/percutz/news/index/2 (page 2), pagination shows properly!
http://localhost/percutz/news/2
First New < 1 [2] > Last New


My routes.php

Code:

$routes['news/(:num)'] = 'news/index/$1';

Thanks!
