[Boost-users] boost multiindex: trying to create a template

I am trying to do the following in order to create a templatized data structure which is both hashed and sequenced..

template <class T>            // class T will always have a member clientid
class seq_hash_list {

typedef multi_index_container
<
T *,
indexed_by
<
sequenced< >,
hashed_unique<member<T,nid, &T::clientid> >
>
> client_info_map;
// typedef client_info_map::nth_index<1>::type clinfo_map_hash;
// typedef client_info_map::nth_index<0>::type clinfo_map_list;

public:
client_info_map _clmap;
};

This compiles fine. But when i uncomment the two index typedefs (above), the compilation fails saying "ISO C++ forbids declaration of `nth_index' with no type".

Is there any other way of achieving the same result?

Thanks,
Sharad
