[ZPT] Error using tree-example

[Gitte Wange]

Hello,

I have tried to create a tree-view.
I looked at the zpt-examples and tried to use the tree-example at my cmf =
site.
(I could see the example without any errors).

At my cmf site I got this error:
IndexError
string index out of range.

Then I went back to look at the example and I get the exact same error :-=
(
The traceback is:

Any good ideas ?
The only thing I did from when it was working and untill I got the error =
was 1=20
restart of the instance.

Zope.org has finally hit the 2gb barrier. I have taken
it down for the moment, whilst I work out what to do.
