For the people who have problems with dtml-tree's "urlparam" only handling constants... I patched "lib/python/TreeDisplay/TreeTag.py" so that I can have a parameter "urlparam_var", an object on the namespace that holds the querystring I want to insert. This is the first time I patched zope internals, but it works fine. Maybe someone who knows better can comment on this. in __init__ I inserted another parameter urlparam_var: args=parse_params( ... urlparam=None, urlparam_var=None) in tpRenderTABLE I added rendering of "urlparam_var" and made sure there's no "urlparam" being passed at the same time: ... # Propagate extra args through tree. (I only changed the block that starts with this comment) if args.has_key('urlparam_var'): if args.has_key('urlparam'): raise ParseError, _tm( 'urlparam and urlparam_var given', 'tree') tmp=args['urlparam_var'] param = md.getitem(tmp, 0) param = "%s&" % param elif args.has_key('urlparam'): param = args['urlparam'] param = "%s&" % param else: param = "" ... That's it. Now, I just have to set the query string by inserting a DTML variable that holds it, for example a REQUEST variable: <dtml-call "REQUEST.set('querystring', myString)"> <dtml-tree ... urlparam_var="querystring"> ... </dtml-tree> Thanks for your comments, hope it helps someone that needs a quick (and cookieless) solution Danny

I'm trying to submit a form to a dtml-document (as action) which i did. But if a have a dtml-tree in the action Document the recursion doesn't work on clicking on the +/- icon when i try to access a dtml-var passed through the form. I answered similar questions at least three times recently (you know the searchable mailing list archives (or Google)?).
Put a feature request into the collector:
you want an "urlparam_expr" attribute for "dtml-tree"....
