[Dune] Parallel nonoverlapping instantionary diffusion problem

I am trying to do a parallel simulation using nonoverlapping grids
(ALUGrid with tetrahedra) for calculating the solution to an
instationary diffusion problem.
My sequential version is working fine. However, the parallel version
does not seem to propagate the solutions on the grid partition
boundaries to the other processes correctly. I started using the code in
"instationarytest.cc" and for the parallel version I am using
typedef Dune::PDELab::NonoverlappingConformingDirichletConstraints CON;
as the constraints type and set the last template parameter of my
Dune::PDELab::GridOperator template instantiations to "true". In
essence, my code still looks pretty much like in "instationarytest.cc"
with the mentioned modifications.
Did I overlook something important for that kind of problem? How is
responsible for communicating solution values between grid partition
Thanks a lot for any hints,
