This problem is also in Zope Version 2.0.1 !! It wasn't corrected. - Achim On Sep 8, 14:55, Martijn Pieters wrote:

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.
