[Zope] Zope 2.2 beta 1 released

[RNDr. Peter FREIMANN]

I have unistalled 2.2a1 and installed a fresh copy of 2.2b1 on Win98 SE.
When I open
the Quickstart examples, click on any second level check boxes
(e.g. Database Integration->A Baisc Example) it would not open but gives the
following error
instead:

Zope has encountered an error while publishing this resource.

Error Type: TypeError
Error Value: len() of unsized object

Anybody can help ?

p.f.

p.s. traceback follows ...
