Resource Controller extra method gives NULL wtih Route::Input 

When add new extra methods to a resource controller in Laravel 4.1 or 4.2,
and if you want to this methods in filters or anywhere with Route::input values it has NULL value!

For example: 
default actions 
/resource/{resource}/edit
/resource/{resource}
gives value {resource} 

but if we add extra method 
/resource/{resource}/upload
it gives NULL when use Route::input
