[Zope] ZCatalog Object Identifier

[Casey Duncan]

Up until recently the CatalogAware base class for ZClasses was not
compatible with virtual hosting. There is a new CatalogAware base class
which alleviates this problem.

As a workaround, create a simple product that registers the
Products.ZCatalog.CatalogPathAwareness.CatalogAware as a base class for
ZClasses (This is available in new Zopes, but not 2.4.x). Then use this base
class in its place. (Unfortunately this means creating new ZClasses and
instances or holding onto your butts ;^).

Alternately you could replace the code from CatalogAwareness module with the
code in CatalogPathAwareness (or make CatalogAwareness a symlink to
CatalogPathAwareness). This should work equally well with no class/object
rebuilding necessary (just do a full clear and reindex). I would do this in
a test environment first just to make sure nothing breaks.

hth,
