Re: [Zope-DB] key error on query variable in previous and next batches
We noticed that also, but figured it was a problem on our part. We are on 2.7.5 and have noticed this only on this version. Very frustrating. -Allen Henk Laloli wrote: Inside the code generated by the zope search interface dtml result page a batch variable 'query' is used in Zope 2.7.6. This gives a key error when having next and previous batches. It also seems to be used in the ZSQL methods query template because the same error occurs there when having more than 20 results (the batch value). Does anybody know about this? In the dtml template it is easy to change, but I can't do much about the ZSQL template.
