Hello, I feel a need to invalidate a dataskin attribute cache after it has been edited, because other objects might want to use the just modified dataskin, but with the new values. Of course, these values come from some attribute providers that should be re-queried. Any thoughts? It seems that the only way is to redefine _v_attrCache.
