Hi Adam
You need location information (-> __parent__) for this setup. Regularly the object knows that information not until its addition to a container. Subscribe to ObjectAdded event and do the same setup within the handler and it will work.

I'd like to provide some default utilities for my sub-site.
As I checked there is the nice ensureUtility method but as it turns
out it failes with

...
 Module szscreen.app, line 339, in __init__
   'WorkflowUtility', WorkflowUtility, 'wfu')
 Module zope.app.appsetup.bootstrap, line 66, in ensureUtility
   name, **kw
 Module zope.app.appsetup.bootstrap, line 74, in addConfigureUtility
   utility_name = addUtility(root_folder, utility_type, utility_factory, **kw)
 Module zope.app.appsetup.bootstrap, line 83, in addUtility
   package = getSiteManagerDefault(root_folder)
 Module zope.app.appsetup.bootstrap, line 105, in getSiteManagerDefault
   package = traverse(root_folder, package_name)
 Module zope.app.traversing.api, line 96, in traverse
   return traverser.traverse(path, request=request)
 Module zope.app.traversing.adapters, line 120, in traverse
   curr = IPhysicallyLocatable(self.context).getRoot()
 Module zope.app.location.traversing, line 90, in getRoot
   raise TypeError("Not enough context to determine location root")
TypeError: Not enough context to determine location root

when it checks the existence of the utility it uses
 sm = root_folder.getSiteManager()
but when it wants to add the non existing utility
 package = getSiteManagerDefault(root_folder)
which in turn wants to traverse like this
 package_name = '/++etc++site/default'
 package = traverse(root_folder, package_name)

Is there any way to easily solve the task?

Excerpt from szscreen.app:

class IApplication(IReadContainer, IPossibleSite, IAttributeAnnotatable):
     ""

class Application(Persistent, SampleContainer, SiteManagerContainer):

       implements(IApplication)
def __init__(self):
               SampleContainer.__init__(self)
sm = LocalSiteManager(self)
               self.setSiteManager(sm)

               ...
ensureUtility(self, IWorkflowUtility,
                       'WorkflowUtility', WorkflowUtility, 'wfu')
