From: Andreas Jung [mailto:[EMAIL PROTECTED]]
Take a look at PloneBatch.py from the Plone package.
PloneBatch.py is a very sophisticated module for batching and
forget about dtml-in.
That doesn't really solve my problem. I don't use ZPT and I don't use
Plone, and the PloneBatch module doesn't strike me as a particularly
beautiful solution to the problem (mostly because of the extremely
verbose ZPT syntax, I guess). In any case, my problem was with
dtml-in...
Unless someone says otherwise I'm assuming it's a bug in dtml-in and
will submit it to the collector in a day or so.

Hello,
I'm trying to implement a Google-like pagination using the dtml-in
batching system, and I'm getting some very strange
results. Either
I'm overlooking something obvious or there is a problem
with dtml-in.
See attached source code of simplified example that produces the
strange results.
The first time I access the page the results are as follows:
0-9 10-19 20-29 30-39 40-49 50-59 60-69 70-79
If I click '10-19' it'll take me to batch_start=10, which gives the
following strange results:
0-8 10-19 19-28 29-38 39-48 49-58 59-68 69-78 79-79
I have no idea why the first batch is now 0-8 and the next batch is
now 19-28. Shouldn't they be 0-9 and 20-29 like above?
I'm using Zope 2.6.1 precompiled Linux version.
