One of my DTML Methods just had this problem as well. It was when I moved from Zope 2.7.0b4 -> 2.7.4 and only seemed to corrupt this one file.

Traceback (innermost last): 

Module ZPublisher.Publish, line 101, in publish 
Module ZPublisher.mapply, line 88, in mapply 
Module ZPublisher.Publish, line 39, in call_object 
Module Shared.DC.Scripts.Bindings, line 306, in __call__ 
Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec 
Module App.special_dtml, line 175, in _exec 
Module Shared.DC.Scripts.Bindings, line 320, in __render_with_namespace__ 
Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec 
Module App.special_dtml, line 175, in _exec 
Module DocumentTemplate.DT_Util, line 198, in eval
__traceback_info__: RESPONSE 
Module <string>, line 0, in ? 
AttributeError: 'NoneType' object has no attribute 'setHeader' 

I could open it through the external editor link and in that way was able to delete it and replace it with a new one with the same code. Seems to work fine now. Odd.

So removing security assertions "solved" the problem?
That doesn't sound good ;-)

What's the example you're referring to?

from Patrick:
This turned out to be security related - I was basing my  product on the example in the Zope Bible, and that apparently doesn't work under 2.7.  Once I deleted all security declarations from my product, it works (albeit without security.)

Sorry for the bad bug, although it might be helpful if the error messages could be more meaningful.  (I'm a newbie, so I have no idea how that could be made to happen.)

Thanks for looking at this,

Patrick

I wonder if this is related?

Did this ever get solved?

I have an unreproducable but logged example of a call to /manage_page_style.css resulting in this...

Please provide the part of your code that refers to RESPONSE and setHeader.

Asked about this on the zope email list, and was told I probably needed to file a bug report.  Will be happy to provide full source if that will help.

I'm getting the following errors in relation to a
product I'm building, and can't seem to figure out why.  It appears to
me that the dtml method is not getting a RESPONSE object, but I've no
idea what could cause that.  Any help would be GREATLY appreciated, as
I'm very new to zope and really can't seem to figure this out.

Thanks!

Patrick
