I've stumbled upon a strange problem with dtml-tree in version 2.2.5 (the
problems occurs in the same way in any of the 2.2.x version), but didn't exhibit
itself in 2.1.6:
Here's some (very) crude code to generate a tree object:
-
class Tree:
def __init__(self, val='top'):
self.name = val
self.tpId = val
def tpValues(self):
tlist = []
for i in range(8):
tlist.append(Tree('me: %s' % i))
return tlist
def build():
return Tree()
--
Now if I attach this to an "External Method" called "mytree" which references
the function "build()", and I write the following DTML:
-
-
In version 2.1.6, I obtain a tree, it's composed of 8 items and each expands
into 8 more, etc...
If I do the same thing in version 2.2.5, I get an authentication failure... even
though I'm logged on as superuser or an admin user... I've tried this on a fresh
install to ensure nothing gets in the way. The error I get is:

Sorry, a Zope error occurred.
