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. ----------------------------- <dtml-let batch="_.range(100, 180)" batch_size="10" batch_start="REQUEST.get('batch_start', 0)"> <dtml-in batch start="batch_start" size="batch_size" overlap="0"> &dtml-sequence-item;<br> </dtml-in> <dtml-in batch start="batch_start" size="batch_size" previous overlap="0"> <dtml-in previous-batches mapping> <a href="<dtml-var URL><dtml-var sequence-query>batch_start=&dtml-batch-start-index;"> &dtml-batch-start-index;-&dtml-batch-end-index; </a> </dtml-in> </dtml-in> <STRONG>&dtml-batch_start;-<dtml-var "batch_size + _.int(batch_start) - 1"></STRONG> <dtml-in batch start="batch_start" size="batch_size" next overlap="0"> <dtml-in next-batches mapping> <a href="<dtml-var URL><dtml-var sequence-query>batch_start=&dtml-batch-start-index;"> &dtml-batch-start-index;-&dtml-batch-end-index; </a> </dtml-in> </dtml-in> </dtml-let>
