Aug 7, 2010 at 11:55 comment added BCnrd This "class group" terminology is meant in the sense of "Weil divisors modulo principal divisors" (e.g., a non-principal height-1 prime ideal) rather than the alternative meaning with invertible modules/sheaves (which is trivial for a local ring). But this notion of "class group" doesn't make sense for abstract modules, merely ideals in the ring. So can you rule out that the non-principal height-1 prime over the completion may be module-isomorphic to the completion of a finitely generated module over the henselized algebraic local ring (as in the correct form of the question)?
