Hi,
I tried to use the TurboGears 2 TreeView example , but I got the error
below:
UndefinedError: <pylons.util.ContextObj at 0x268b770
action=u'routes_placeholder', controller=u'root', controller_url='',
environ={'routes.route': <routes.route.Route object at
0x00EB2550>, ...ate'}, form_errors={}, form_values={}, identity=None,
pylons=<pylons.util.PylonsContext object at 0x0268B7D0>,
start_response=<function repl_start_response at 0x02674670>,
url=u'about'> has no member named "tree"
Looks like tmpl_context has no member named "tree". Am I missing
anything here? Please shed a light on how to debug this? Thanks much
in advance.

>From my controller (root.py):
===================
import pylons
from pylons import *
from tw.jquery import TreeView
@expose('helloworld.templates.about')
def about(self, **kw):
myTree = TreeView(treeDiv='navTree')
pylons.c.tree = myTree
return dict()
Here is my about.html
