Impossible to create a wiki page into plone : the error is
NoneType object has no attribute keys
Workaround: add "or {}" to the end of line 61 in Outline.py, or upgrade to the latest from CodeRepos.
if anyone else gets this, please note here --simon, Wed, 02 Mar 2005 12:34:11 -0800 reply

I can verify this error too. ZWiki 0.39, Win32, vanilla Zope 2.7.4
Ditto, in Zopes 2.7.x -- Thu, 03 Mar 2005 14:17:53 -0800 reply
I just ran into this last night, with Zope 2.7.4 on Linux. Tried previous Zopes, same problem. This is corrected by the fix above, adding : "or {}" to Outline.py at the end of line 61. Recent Zopes give the full error message as follows:

Darn, thanks.
A better fix may be... -- Fri, 04 Mar 2005 13:01:59 -0800 reply
The Outline class already has proper initialization of the childmap. Instead you may want to fix the code that is circumventing that.
Add "if oldchildmap is not None:" before line 227 of OutlineSupport?.py.

I am able to work with exist data.fs -- Mon, 07 Mar 2005 16:53:07 -0800 reply
If I work within a ZWiki folder obtained by using a data.fs file from a backup, I'm able to create ZWiki pages; but I am not able to create ZWiki pages in a new folder.
Fix works for me -- Wed, 09 Mar 2005 20:45:05 -0800 reply
Thanks. "or {}" worked. That was hair raising while it lasted. My platform:
