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

[Jachin Rupe]

hi there

Thanks for the reply.  Removing the class attribute from the page  
directive got rid of the error.  However I'm not overriding the  
VinePackage class.

class VinePackage(BTreeContainer):
	
	implements(IVinePackage)
	
	title = u""


Since it is inheriting from BTreeContainer, perhaps that overrides  
the constructor?  I'll look into it and if I find an answer before  
someone else offers one I'll post it.
