Hello Zope users!

The following construct works in Zope-2.0.0b6: <!--#tree dox leaves="objectValues(['Folder', 'DTML Document'])" sort=id reverse-->

I've now switched to Zope-2.0.0 and the above reverse sort produces an AttributeError. I still can do reverse sort with the #in tag! What's different in 2.0.0 or how can I do a reverse sort with the #tree tag??

Thanks for your advice.

Congratulations, you have found a bug, When Chris subtly changed the way the reverse is performed in both in and tree tags, he made a mistake in the tree tag, and must have missed it. The Tree class uses two TreeDisplay Module functions (note: not member methods of the Tree class) to display your tree, and within those functions 'self' is the same as the _.this() object. In case of a DTML Method, it's the Method's parent in the acquisition path. Chris, however, thought it would be the Tree class itself. That class has a new method, reverse_items, which he thought he could call with self.reverse_items. What happens is that that method is looked up in your acquisition tree, where it is not present. Solution: Remove the reverse_tems method at line 158 and change items=self.reverse_items(items) (line 345) to: items=list(items) items.reverse() Warning: I did not test this, but I am sure it'll work. I'll report this to the Collector. -- 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 ------------------------------------------
