After I've created a wiki folder, and edited the front page a couple of times, I went to the History form and clicked "full history." Got a Zope TypeError?, "len() of unsized object".

This with Zope 2.6.1 and Plone 1.0.3 on RedHat? Linux 7.2, Python version 2.1.3.

Post the traceback. Thanks.

Don't actually get a real traceback... the Plone page displayed loks like:

Site error This site encountered an error trying to fulfill your request. The errors were: Error Details Error Type TypeError? Error Value len() of unsized object

traceback --SimonMichael, 2003/07/30 22:43 GMT reply

Ok - have a look in /error_log in the ZMI, you should be able to get the from traceback there - or from your EventLog.

Also, compare with #370 Type Error when clicking full history.

here is the traceback --2003/08/01 04:42 GMT reply

Doesn't look quite the same, i think:

We were seeing this on plone.org. Alan made a change to plone and now anonymous and members see:

Historical not available
This class does not support the historical interface.
The content must mix-in OFS.History.Historical

but managers see the normal page history listing (plone's history_form). Maybe related to [#208 in page history, "copy to present" or viewing old revisions always requires authentication]? ?

Name: '#567 TypeError? on Full History' => '#567 Full History/history_form gives TypeError? or Historical not available' Category: user-browsing => other Status: open => closed

You can see the problem at http://plone.zwiki.org/FrontPage/history_form . When logged in as a manager, the form works fine. So I believe this is a cmf/plone bug (misleading error message).
