Shane, it does not work:

I created a file called demoCatalogTool in PTKDemo which has the
followingcontent:
from Products.PTKBase.CatalogTool import CatalogTool
from Products.PTKBase.PortalObject import PortalObjectBase

class DemoCatalogTaol (CatalogTool):

    def __init__(self):
        CatalogTool.__init__(self)
        # add all Seres indexes
        self._catalog.addIndex('Project', 'FieldIndex')
        self._catalog.addIndex('Consortium', 'FieldIndex')
        self._catalog.addIndex('NotOnMainPage', 'FieldIndex')
        # add meta data
        self._catalog.addColumn('eventDate') 

in Portalobject only PortalObjectBase exists. 


Changed __init__.py:
..
import PropertiesTool, DemoInterfaceTool, DemoMembershipTool,
DemoCatalogTool
..
tools = ( DemoInterfaceTool.DemoInterfaceTool
        , DemoMembershipTool.DemoMembershipTool
        , DemoRegistrationTool.DemoRegistrationTool
        , DemoCatalogTool.DemoCatalogTool
        , URLTool.URLTool
        )

Changed Portal.py:
        addPTKBaseTool(self, 'PTK Basic Actions Tool', None)
        # addPTKBaseTool(self, 'PTK Basic Catalog', None)
        addPTKBaseTool(self, 'PTK Basic Discussion Tool', None)
        addPTKBaseTool(self, 'PTK Basic Workflow Tool', None)
        addPTKBaseTool(self, 'PTK Basic Undo Tool', None)

        addPTKDemoTool =
self.manage_addProduct['PTKDemo'].manage_addTool
        addPTKDemoTool(self, 'PTK Demo Membership Tool', None)
        addPTKDemoTool(self, 'PTK Demo Registration Tool', None)
        addPTKDemoTool(self, 'PTK Demo URL Tool', None)
        addPTKDemoTool(self, 'PTK Demo Interface Tool', None)
        addPTKDemoTool(self, 'PTK Demo Catalog', None)

When restarting Zope the PTKDemo product is broken. Traceback is:
Traceback (innermost last):
  File "/usr/share/Zope-2.2.2-linux2-x86/lib/python/OFS/Application.py",
line 397, in import_products
    product=__import__(pname, global_dict, global_dict, silly)
  File

line 56, in ?
    tools = ( DemoInterfaceTool.DemoInterfaceTool
AttributeError: DemoCatalogTool

Where do I go wrong?
