[Zope3-Users] error headache: __init__() takes exactly 1 argument (3 given)

[Bernd Dorn]

did you override the constructor in vine.vinePackage.VinePackage or  
one of its superclasses?

iv yes, then you need

def __init__(self,context,request):
     ...

as constructor, you can test it by just removing the class attribute  
of your page directive
