[Zope] ANN: patch to <dtml-tree> adds urlparam_expr

[Danny William Adair]

Hi!

I patched TreeTag.py so that <dtml-tree> accepts a new parameter
"urlparam_expr". It works like urlparam, except that it will take a python
expression and evaluate it before creating the querystring for the expanding
and contracting widget links.

It's a "hotfix product", so you don't have to change your Zope sources.
You can get it here:

I've put the feature request for <dtml-tree> in the Collector, too:
http://classic.zope.org:8080/Collector/bugsAndFeatures

It's only three little locations that I patched. Maybe someone that knows
Zope better than I do can have a look and verify that the patch is ok. Seems
to me, but you know...

Thanks,
Danny
