Hi Tres

Thanks for your answer. Could I trouble you a little bit more please?

I don't know where I'd put these fragments (and the last one seems incomplete, perhaps intentionally?). I'm happy to read and code myself, so I don't mean to ask for much here, but I'm not sure what to do with your suggestion. I read version 2.6 of the zope book, and today found out there's a proto-version 2.7, which I'll take a look at.

Note that the "new way" stuff is only for Zope *later* than 2.8.x. In that case, you would define the function in a module somewhere on your $PYTHONPATH (e.g., in $INSTANCE_HOME/lib/python, or in a product) and then register it in a ZCML file which is included from your 'site.zcml' (in $INSTANCE_HOME/etc).

Anyway, thanks again.

Terry
