[Zope] ac_acquire error happens after inheriting from Folder

[Palermo, Tom]

All,
 
I have a class called Contact that is now inheriting from Folder. After I
did this, I get the following error when attempting to add a new Contact:
 
Exception Type   AttributeError
Exception Value  aq_acquire
 
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 Products.PythonScripts.PythonScript, line 323, in _exec
    * Module None, line 27, in validateContact
      <PythonScript at /validateContact used for /contacts>
      Line 27

    * Module OFS.ObjectManager, line 211, in _subobject_permissions
 
AttributeError: aq_acquire
 
I thought it might be due to not having an __ac_permissions__ in my class
definition but that didn't seem to change anything and Folder already has
this so my Contact class should pick up __ac_permissions__ from Folder. In
the above traceback, line 42 in manage_addContact is this (the part inside
the if statement is line 42): 
                #change permissions based on value of private
                if private==True:
 
self.manage_permission('View',['Authenticated','Content Manager','Manager'])
                else:
                        self.manage_permission('View',acquire=1)
 
Any ideas would be much appreciated. The error is clearly related to
inheriting from Folder as it wasn't there before. I just don't know why the
error happens.
