[Zope3-Users] mapply error

[David Johnson]

I have a content type that gives the following exception whenever I  
try to click on it.  Not sure why.  Any ideas?

   File "/usr/share/zope3/lib/python/zope/publisher/publish.py", line  
56, in unwrapMethod
     raise TypeError("mapply() can not call %s" % `object`)
TypeError: mapply() can not call None

How can I troubleshoot?

Thanks in advance.

David
