Hi,
Please note that the first index works const hndl_index_type &h_type = boost::multi_index::get<hndl>(ns); NodePtrSet::const_iterator it = h_type.find(theHandle); //works
but if I try to access the 2nd index doing: ... const group_index_type &g_type = boost::multi_index::get<group>(ns); NodePtrSet::iterator group_it = g_type.find(aGroup);
I get the following output error:
[...] Replace NodePtrSet::iterator group_it = ...; with group_index_type::iterator it = ...; NodePtrSet::iterator (which is the same as hndl_index_type::iterator since hndl_index_type is index #0) is a different type than group_index_type::iterator, which is associated to index #1. You cannot freely mix iterators from different indices, though if the necessity arises you can convert between them with project() capabilities: http://boost.org/libs/multi_index/doc/tutorial.html#projection HTH, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
