I have been thinking about this lately.

When changing the default catalog, you are still indexed in the old catalog 
(if there was a catalog with the old default name), because adding a 
CatalogAware based ZClass instance causes it to add itself to the default 
catalog.

Also, you are not yet indexed in the new default catalog, yet we use 
reindex_object, which first removes you from the catalog. Right now, this 
is not an error, it silently ignores this.

In the future however, this may become an error. Therefore, the proper way 
of changing the default cataloger is:

   <dtml-call unindex_object>
   <dtml-call "manage_editCataloger('newCatalogID', REQUEST)">
   <dtml-call index_object>
