The problem with the above code is that if index_html is acquired from the parent folders my hasattr test is true. I want it to be false in the case of acquisition. Most of the time (in all practical cases),

if hasattr(folder.aq_explicit, 'index_html'): will work. When you search the mailing list archives for a post "Unexpected acqusition behaviour", you will see some cases, where it will not work. A safe solution is to use "aq_base" (instead of "aq_explicit"). "aq_base", however, is only be allowed in External Methods... Dieter
