Hi,
I am red faced (and blurry-eyed, its 1am here)- I found the answer
in the archives, in September:

Just return the data; it is handled properly now.

Hi,
I was having a look at Phillipp's fabulous book (thanks!), and came
across the code for publishing a PDF document to the browser (this is
slightly modified from the book):
from zope.app import zapi
from zope.app.publisher.browser import BrowserView
from ccard.pdf.interfaces import IPDFPresentation
class PDFView(BrowserView):
def __call__(self):
pdf = zapi.getViewProviding(self.context, IPDFPresentation,
self.request)
filename = zapi.name(self.context) + '.pdf'
response = self.request.response
response.setHeader('Context-Disposition', 'attachment; filename=%s'
% filena
me)
response.setHeader('Content=Type', 'application/pdf')
response.setHeader('Content-Length', len(pdf.data))
response.write(pdf.data)
However, these days I get the error:
2005-12-28T15:29:56 ERROR SiteError

response.write(pdf.data)
AttributeError: 'BrowserResponse' object has no attribute 'write'
What is the correct technique, now that BrowserResponse does not have
write()
TIA, and Happy New Year
