I can see how this problem would arise. My view is that it's the result
of us having to wrestle with an ageing commenting infrastructure in
plone. Without knowing anything about the specifics of qPloneComments,
I'm sure it'd be possible to tweak things to get it to work - presumably
by overriding the discussionreply view in quills.app
- but that'd be
throwing hack after hack, IMHO.
Happily, work is well and truly afoot to replace the old commenting
infrastructure with something much better (i.e. more pluggable, for our
purposes) - <http://pypi.python.org/pypi/plone.app.discussion/
Aspeli (cc'd), who is the mentor for the GSoC project implementing this,
says that the new codebase should be able to handle our needs. The
target for plone.app.discussion is Plone 4, however, and I don't know if
it will work with Plone 3.X, so perhaps not a short-term solution...
