[Zope] ZWiki RecentChanges don't work in Zope 2.2.x

[Chris Withers]

...you get an authorization error :-(

This is because this Wiki isn't (and shouldn't) be publicly viewable or
editable.

So, Anonymous doesn't have 'View' permission on the folder. I've given
Anonymous 'Access Contents Information', the usual nasty hack I had to
do before, but now that just changes the error message :-S (it's in a PS
below)

I guess the Interfaces Wiki does pretty much this, but RecentChanges
works there. What tweaks to permissions and code have been made there?

This all stems from the fact that DTML in Wiki code _always_ executes
with the Anonymous role. That's stoopid :-(
Wouldn't it make more sense for it to execute with whatever Proxy Roles
that Wiki Page has?
I would code this myself, but I don't know how. Any ideas?

Any other thoughts about the problem?

cheers,

Chris
