Hello Andy
Must admit I cant be bothered to read all this but some notes:
<input type="hidden" name="" value="<dtml-call "RESPONSE.redirect('toondecr2?datum=%s&teller=%s' % (datum,teller))">>">
This is pointless, the page will never be rendered because it will instantly do the redirect. If you could refactor this a bit to more concise question...
Gosh, you're harsh. I'll try. Why the instant redirection? I want to make the redirection conditional on clicking the submit button. Why _does_ it work as I'd like it to when in a separate form (you don't have to read this;)? The following produces an almost empty webpage with just a submit button. The required action is only undertaken when the submit button is pressed: <form method="post" action=""> <input type="submit" name="x" value="> "> <dtml-if x> <dtml-call "REQUEST.set('datum', _.str('1796/03/11'))"> <dtml-call "REQUEST.set('teller', 5)"> <input type="hidden" name="" value="<dtml-call "RESPONSE.redirect('toondecr2?datum=%s&teller=%s' % (datum,teller))">"> </dtml-if> </form> Cheers, Dirk
