Hi James,


If you sort by modification time in reverse order and set batchsize to 1 
then I think you'll get the latest instance.

Example:

   <dtml-in "Catalog.searchResults()" sort=bobobase_modification_time
    reverse size=1>
    ...
   </dtml-in>


I'm not sure it's the best way, though.


Alexandre
