Looking back in history: https://mail.zope.org/pipermail/zope-dev/2008-August/032902.html I guess one or other of us has the parameter order wrong, probably me. Much thread ensued: https://mail.zope.org/pipermail/zope-dev/2008-August/thread.html#32902 https://mail.zope.org/pipermail/zope-dev/2008-September/thread.html#33174 Some justification for keeping the status quo from Fred: https://mail.zope.org/pipermail/zope-dev/2008-September/033172.html I stand by my resultant request here: https://mail.zope.org/pipermail/zope-dev/2008-September/033170.html Maybe less people care about ZCA now and so we might actually get sensible changes made. Maybe forking would be easier... cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )
