Hi again,

The ComponentLookupError have re appeared!

 > Error object: (<InterfaceClass zope.app.intid.interfaces.IIntIds>, '')

What happend was that I had a IntId utitlity in the root site (renamed 
to '') that answered the request when I added the Indexes in a sub site.

So the question is how do I rename the IntId utility programmatically
or why doesn't the following code ad a utility (maybe it's not
registered correctly to be use right after it's been added but needs
some events to trigger first???

First I do this:

         intids = IntIds()
         tools['intid'] = intids

#I thought this was equal to rename the intid-util to ''!?
         intids_reg = UtilityRegistration('', IIntIds, intids)

         intids_reg.status = ActiveStatus

Right after that I do this:

         catalog = Catalog()
         for index_name, index_attribute, idx_if, attr_call, index_type 
in indexes:
             idx = index_type(index_attribute, idx_if, attr_call)
             catalog[index_name] = idx
         tools['catalog'] = catalog
         catalog_reg = UtilityRegistration('catalog', ICatalog, catalog)
         catalog_reg.status = ActiveStatus

This is all called from an event handler, like Dominik pointed out I 
should do it.
