Once again, I've run into a compilation problem that I can't seem to fix and I wish some help. My multi_index container looks like: typedef multi_index_container< entry, indexed_by< ordered_unique<member<entry,DataVertex,&entry::m_vertex> >, ordered_non_unique< composite_key< entry, member<entry,size_t,&entry::m_y>, member<entry,size_t,&entry::m_x> > > >
C;
I now have to swap values via the composite_key. To simplify things, I'll just express the last of three lines that would do this job if it compiles (and the lines needed to understand it). c.get<1>().modify_key(c.get<1>().find(make_tuple(y,UINT_MAX)),ll::_1=make_tuple(y,startIter2->m_x)); where startIter2 type is: nth_index<C,1>::type::iterator and y is just an int. The compiler error that I get is: $BOOST_ROOT/boost/multi_index/detail/modify_key_adaptor.hpp: In member function 'void boost::multi_index::detail::modify_key_adaptor<Modifier, Value, KeyFromValue>::operator()(Value&) [with Modifier = boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::other_action<boost::lambda::assignment_action>, boost::tuples::tuple<boost::lambda::lambda_functor<boost::lambda::placeholder<1>

Can somebody point out whats wrong?
