This example here :-

with the external method

class _dummy:
    def __init__(self, name):

def child_lookup(parent):
    c = []
    for i in range(0,5):
        c.append(_dummy("%s.%d"%(parent, i)))
     return c

and dtml method

<dtml-let name="0">                        
<dtml-tree id=name branches_expr="child_lookup(parent=name)">
<b><dtml-var name></b>

appears not to work on zope 2.2.0 or 2.1.6 on RH 6.2 with netscape
4.7x, python 1.5.2

Every node gets the label "0" and then stops expanding.

I also tried a simple example starting with a root of 1 and
computing leaves of 2x and 2x+1 but that also fails.

Any ideas what is goind on?
