Second question dealt with <dtml-tree branches_exp="some_sql_statement" leaves="dtml_method>. I patched the treetag.py file, but expand_all=1 does not expand the leaves. I'm not sure if this is intended or is a bug.

I hope my "some_sql_statement" you mean a ZSQL mthod. If you've just put an SQL statement between the quotes then you have an understanding problem of how Zope works ;-) Can you post me (or the list) the SQL method and the DTML method. Maybe even a .zexp with containing both of them? cheers, Chris
