BTW: I am currently doing this by creating a member function that expose the value of the inner member of the member and use BOOST_MULTI_INDEX_CONST_MEM_FUN.
Thanks

Hi All,
Is it possible/exist a key extractor that can extract a member of a member of the base type stored by the Multi Index container. I tried to do this with the standard member extractor but failed to do so.
