[Zope] CoreSessionTracking - looping over items

[Chris McDonough]

Please try to keep correspondence on the list.

THis can't be done from DTML if you're using an internal session data
container because DTML can't access attributes with a leading underscore.
Either use an external session data container or use an external method.
For instance, here's an external method that returns the number of session
data objects in the internal session data container, along with some DTML
that calls it.

def numberOfDataObjects(session_data_manager):
    return len(session_data_manager._sdc)

<dtml-var "numberOfDataObjects(session_data_manager)">

HTH,
