[Zope] ZSQL and batch processing

15 Nov 1999

      Hello,

I try to make a batched output from an ZSQL result. I got
the previous link working. But whatever I do no next page
link will be shown. Did anybody already make this thing
work? 
I have 23 objects returned and only five will be in one batch. 
That part works fine (easy going, out of the box). When
I give different qs parameter it works. Only the "next page"
link doesn't show up. Any suggestions?

Please find my code below.

Thanks

Ulli
