Hello Andreas,

I can't compile your source right now, but from the looks
of it I cannot see anything wrong.
What compiler are you using? If MSVC++ 6.0 or 7.0, take into
account they have non-conformances you must take into account
when using Boost.MultiIndex, see

http://boost.org/libs/multi_index/doc/compiler_specifics.html

Your particular code won't work on either of these compilers
due to problems with member<> and composite_key that are
addresses in the aforementioned page.

Is this the problem? If not, I'll try to get back to you
in a couple of days.

Best,
