[Zope] <dtml-tree query_expr="xxx"> PATCH !

Hi ! In order to solve the problem I mentionned two days ago about the <dtml-tree> tag with non-persistant REQUEST.form data, I wrote a patch to apply to the Zope 2.1.6 root source path. It just adds a new tag attribute, "query_expr", to the dtml-tree tag, and you can assign this attribute the REQUEST.form value. Everything is explained on http://www.en.xlogx.org/Zope and the patch (Zope 2.1.6) is downloadable from there. I hope this helps.... P.-J.
