Installed Zope 2.6.1beta1 today and on a particular webpage I have created I get an error (no big deal) Error Type: RuntimeError Error Value: external method could not be called because it is None Fair enough, but where's the traceback? I run it with -D and there's nothing in the HTML. I have never seen a Zope error before without a traceback. Is there a reason? Is it a bug? Peter
