[Zope] ZWiki RecentChanges problem with 2.1.6

[Chris Withers]

Hi,

The RecentChanges page in ZWiki no longer works in 2.1.6

The following code:
<dtml-in "aq_parent.objectValues(spec='ZWiki Page')"
sort=bobobase_modification_time reverse>

Spits authorization errors even when I'm logged in as root.

Anyone got any ideas?

cheers,

Chris
