I can think of two possible things.

One is that you are maybe getting a form validation error and then  
pressing Apply, or that you are using a widget that redraws the screen.

Another is that we might have a bug that makes form variables be  
stomped on by header names. :-(

First try changing

to

def referer(self):
     return self.request.form.get('HTTP_REFERER') or  
self.request.getHeader('HTTP_REFERER')

Then if that doesn't work, try changing it to

def referer(self):
     return self.request.form.get('referrer') or  
self.request.getHeader('HTTP_REFERER')

and changing your template to have
>    <input type="hidden" name="referrer" value=""
>         tal:attributes="value view/referer" />

(Sadly, the spec made a spelling error with "referer". :-) )

Yeah, they are rearranging things at PyCon.
