[Zope] TTWTYPE atribute error

[Patrick Gelin]

Hi,

I've just installed TTWTYPE and add the AddTTwObject permission to my
container (deriver from Plone folder). if I want to validate a TTWObject I
add I get the error message:

AttributeError: __call__

Below is Formulator.MethodFiel:

class Method(Persistent, Acquisition.Implicit):
    """A method object; calls method name in acquisition context.
    """
    def __init__(self, method_name):
        self.method_name = method_name

    def __call__(self, *arg, **kw):
        # get method from acquisition path
        method = getattr(self, self.method_name)
        # check if we have 'View' permission for this method
        # (raises error if not)
        getSecurityManager().checkPermission('View', method)
        # okay, execute it with supplied arguments
line 40 ->   return apply(method, arg, kw)

Is there anybody to help me ?

Thanks.
