CatalogAware looks for a ZCatalog named "Catalog" (with a capital "C").
Make sure the id of your ZCatalog is set to "Catalog" and it is
acquirable by the CatalogAware objects. Therefore it needs to be at or
above the CatalogAware objects in your Zope hierarchy.

A caveat about CatalogAware, it only catalogs objects when the are
created, deleted or moved. When you change their properties they are not
automatically recataloged. To recatalog a CatalogAware object, call its
reindex_object() method.
