I've recently begun trying to figure out how batches work, but what appears simple is instead causing massive problems, and I really don't know what's wrong. I have the following snippets of DTML in an index_html: <dtml-unless first> <dtml-call "REQUEST.set('first', 0)"> </dtml-unless> <dtml-unless batchsize> <dtml-call "REQUEST.set('batchsize', 2)"> </dtml-unless> . . . <dtml-in "jobs.objectValues()" size=batchsize start=first> . . . </dtml-in> Then I have a BatchAdjustForm method which isn't a form anymore due to recent changes, but it looks somewhat like this (note that the text entry field will probably be nuked soon): <table> <tr> <td> <div align="left"> <dtml-if previous-sequence> <a href="<dtml-var URL><dtml-var sequence-query>first=<dtml-var previous-sequence-start-number>&batchsize=<dtml-var batchsize>"><[Previous]</a> <dtml-else> <[Previous] </dtml-if> </td> <td> First:  <input type="text" name="first"> </td> <td> Size:  <select name="batchsize:int"> <option value="5">5</option> <option value="10">10</option> <option value="50">50</option> <option value="100">100</option> </select> </td> <td> <div align="right"> <dtml-if next-sequence> It worked! <dtml-else> [Next]> </dtml-if> </td> </tr> </table> First of all, you'll probably notice that the batchsize is set insanely small. This app is basically a job board, and is meant to iterate through a list of jobs and extract batches. Until recently I had never tested the batch functionality, but yesterday I added 6 jobs to the board and, despite having set the batchsize to 5, all 6 showed. Dropping the batchsize to 4 has the same effect, but 3 or lower works as expected; I'll see 3 items, 2, etc. Maybe I don't understand how size= works? Also, the BatchAdjustForm simply doesn't work. I consulted the batch example in the Zope Book, and borrowed quite a bit from it, but nothing seems to work. As you can probably see, I tried to simplify the 'next' navigation link to print 'It worked!' and avoid using the code I used for the 'previous' link, but this doesn't seem to ever appear, despite the fact that I'm only displaying a few of the 6 jobs currently in my sample database. Any ideas? This isn't a major problem, but it's one of the last which I'm experiencing with this project and it really annoys me that I can't even get a simple batch query to work. :)
