No, actualally, on my way home I just realized that the test-program I
was using just die not test this very method.

I'll fix it, should not be too difficult.

Cheers,

Think I got it. The problem was, that in a const method we can only
construct a const-iterator with GenericIterator. Next problem was the
signature of CommunifationIndexMap::operator[]() which returned an int,
not a const-reference to an int (doesn't matter normally, but spoils the
iterator-facades provided by Dune::Fem.

Marco, could you please check whether the latest commit fixes the error
also on your side? Thanks.

Claus
