Hi Kai:
I installed ZCO 0.7.2 and PrimaGIS 0.5.1, but I have problem with WFS support. I had the same error with ZCO 0.7.1 and PrimaGIS 0.5.1 installation as well (trac-ticket #96) but unlike then, there are no ZCO Datastore configuration errors now.
thanks,
Jagadish
Here is what I have in the event.log:

The ZCO 0.7.0 code assumes that there is a MapRenderer instance with an
id 'mapper' available in the acquisition context that it can use to
render the overview. If you've used the createPrimaGISDemo script you
should have such a MapRenderer instance in your system. For some reason
or another this does not seem to be the case for you though and that is
why you get an AttributeError.
More recent versions of ZCO come with a CMF compatible tool called
'portal_gis' that provides the map rendering services of MapRenderer.
This means that ZCO needs to be installed using the portal_quickinstall
tool (which the PrimaGIS installer will do automatically for you).
I would suggest you try out the latest releases for both ZCO and
PrimaGIS if this is possible. You can download them from
http://www.gispython.org/downloads/zope/
ZCO is currently at version 0.7.2 and PrimaGIS at 0.5.1. If this is not
an option then you need to provide the MapRenderer instance in you ZODB
that the overview can use.

So, I tried manually replacing it without success, but I doubt that the error could be sorted with some correction there. Could someone make better sense out of those changes and suggest me what I might have to correct?
