CatalogAware ensures that objects are added to the catalog *when they are
created*. The easiest thing to do would be to use the Find command in the
Catalog to add the objects.

BTW, those objects are aware that they have CatalogAware as a base class...
you'll probably get an error if you try to delete one, because it is not in
the catalog, and the CatalogAware code will try to remove it from the
catalog.
