[Zope] SiteAccess in 2.0.0b2?

I'm having trouble getting SiteAccess 2.0.0b2 to work with Zope 2.2.0b2. The first odd thing that happens is when I create a new SiteRoot, it says that this object already has a SiteRoot (which it doesn't), but creates it anyway. The second is: it doesn't seem to work at all! The value of URL1 still has the :9080 port and the wrong virtual server. Any ideas? - T.J.
