[Zope-dev] dtml-in: next-batches

[Brett Carter]

I'm running Zope 2.2.2, and I'm trying to use the batching stuff for
the dtml-in tag, however, I can't seem to access any attributes off
the 'next-batches' or 'previous-batches' mapping object that's
supposed to be available, with the attributes 'batch-start-index',
'batch-end-index', and 'batch-size'.  However, my example code (see
below) blows up with a key error when trying to access any of these.
Is this a bug, or am I just misunderstanding how to use this thing?

I wrote an external method to dir the 'next-batches' object, and it
seems the only attributes available are:
['data', 'items', 'query_string', 'start_name_re']
