Config route for two different pages?

[eluser]greedyman[/eluser]
I have two urls like this:
For category page

Code:

http://localhost:8080/nammobile/dien-thoai-di-dong-1.html

For product details page

Code:

http://localhost:8080/nammobile/dien-thoai-di-dong-1/nokia-asha-23.html

I try this code but it doesn't work:

Code:

$route['(:any)'] = "front/group/index/$1"; // for group controller
$route['(:any)/(:any)'] = "front/product/details/$1/$2"; // for product controller

Each route is matched for different controller. I use reg exp but it doesn't work too:

Code:

$route['(#[\w]+-[\w]+-[\d]+#)'] = "front/group/index/$1";

Any idea for this problem? Thanks for watching!
