i have some strange problmes by using the "REQUEST.resolve_url('http://mydomain/...')" in DTML if SiteAccess is active. I have also some Sites in use without SiteAccess and no problems with the above method.
Tell me more about the problem, please. SiteAccess replaces REQUEST.traverse, which is called by REQUEST.resolve_url. Are you just using resolve_url to grab objects given their path?
Getting an object-Context (index_html => DTML Document) by absolute URL: <dtml-with "REQUEST.resolve_url('http://mydomain/home/index_html')"> <dtml-var title> </dtml-with> throws Error Type: ValueError Error Value: Different namespace. If i try to get an object-context of an unexisting object, the snippet above throws the correct message that the ressource wasn't found. On a zope-installation (2.2alpha und 2.1.2) without SiteAccess this example works fine.
