Hello all, and especially Michel =) Why is it I query the ZCatalog, and have the results sorted on a FieldIndex? Something like: res=apply(cat.searchResults, (), {'sort-on': 'aFieldIndex'}) gives me a AttributeError: items on line 411 of Catalog.py. Maybe I am trying something very stupid here. I have a bunch of objects catalogued with a FieldIndex on a DateTime property. If call searchResults without arguments, it all works beautifully, and the result objects sport my DateTime property. But I want to retrieve these objects sorted on the DateTime property. Note that I want the results sorted by the Catalog, I am not using this in any DTML, so I cannot rely on the in tag's sort attribute. I also wanted to use the more efficient sort results of the Catalog, and the advantages of the LazyCat object.. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
