Hello, something like this works with a DTML-Document self.container.REQUEST.RESPONSE.setHeader('content-type','text/html') return self.container[self.next_form](\ self.container, self.container.REQUEST) Doing the same with a zpt runs into a maximum recursion error. If I do not call the zpt the pageTemplate itself is returned, which also gives an error. TIA, __Janko
