[Zope] argh - CoreSessionTracking

[Harry Wilkinson]

Hi all :)

I'm having some problems with CoreSessionTracking.  The errors are
occurring on some pretty simple DTML code and they seem to be caused by
a failure to find the getSessionData() method :S

Here's the code that's getting an error:

<dtml-call "session.getSessionData().set('Type','Professional')">

I've tried splitting this up into three seperate calls like so:

<dtml-let ses="session">
  <dtml-let sesdata="ses.getSessionData()">
    <dtml-call "sesdata.set('Type', 'Professional')">
  </dtml-let>
</dtml-let>

The error occurs on the call to getSessionData() and I can't work out
why.  The same code works in a seperate area of my site, using a
different session data manager (with a different name) and a different
session ID manager.

Is this likely to be an acquisition problem?  The object 'session' is in
the folder directly above this folder.  I have checked and double
checked the security settings of various objects but I'm not totally
certain they're correct.  I get an error when I try to change the
security settings of the 'access session data' permission in the session
data manager.  Is that normal?

I hope somebody can shed some light on this; thanks for your time! :)

Oh yes, and here's the traceback:
