Ah yes... good point.  I was remembering when current_local_solution got turned into a ghosted vector.

Hah - completely agree.

Yes... even some libMesh veterans still screw it up (like I just did!)  ;-)

Hopefully someday... but that would mean someone would need to make ghosted vectors work for all the other linear / nonlinear solver packages.... and so far that hasn't happened.
