Thanks for your answer, but there is something I do not understand:

if results:

an empty result from ZCatlog is false in a boolen condition?

Yes, thats standard Python behavior, empty lists, dictionaries and similar objects are assumed "False" when used as boolean. This means you could even write it this way: return (results and results.actual_result_count) or 0 in python2.5 (not yet supported by Zope) even: return results.actual_result_count if results else 0 Cheers Tino
