[dune-pdelab] Compilation error for Dune::PDELab::FunctionToGridFunctionAdapter

[Eike Mueller]

Hi,

thanks a lot, I've now changed it and it works as it should and I've  
used it to construct the L2norm of the error. What I'm trying to do  
next is construct a grid function which gives the error at each point  
(and I want to save this to disk). Can I do this by constructing  
something like the DifferenceSquaredAdapter and then use the *.vtu  
output routines on this?

Thanks a lot,

Eike
