[Zope-CMF] Tracking discussion replies, catalog-based.

[Ausum Studio]

I'd like to perform a list of replies to an object, using portal_catalog.

The "in_reply_to" index looked like the answer but it doesn't behave like
its name would suggest. Actually, using Zope 2.5.1 and CMF 1.3,
"in_reply_to" has a None value for all responses, not only first level ones.

Would you please suggest me how to obtain a consistent index containing the
path/id to objects that discussion items are replying to?

Thanks in advance,



Ausum
