[Zope-dev] Zope2.7.0rc2 AttributeError: 'NoneType' object has no attribute 'setHeader' - SOLUTION

[Tony McDonald]

Hi all,
You'll have seen my message earlier in the month about the above. Well, 
we figured it out.

To cut a long story short, we had a role called 'SYS' in the folder. It 
was a real forehead slapping moment, with all the team looking around 
at each other with the unsaid thought of 'oops, that's *probably* not a 
good idea'. This was the same day that someone else in the team found 
out that using 'yield' as a variable is also not a good idea.

So, we deleted the role, and Bob's your uncle. Lots of smiles all 
around.

cheers for all the help,
Tone.
