i have an existing zclass with several property sheets which i would like to make CatalogAware so that the class instances automatically re-index themselves when changed. i haven't been able to find any documentation on adding CatalogAwareness after the fact. so, i'm wondering... 1. can it be done ( easily )? 2. is it better/easier to just re-create my zclass? if i need to re-create my zclass, what important pieces of information do i need to save so that the objects which already exist get picked up again when i create the new one? ( eg, the meta type? the zope class id? ) thanks for any help, david -- David McCuskey dmccuskey@bigfoot.com
