[Zope] Problems importing

[Peter Bengtsson]

That error occurs when you're trying to import a Product in anywhere else
than the product folder or when you are sometimes trying to import objects
that contain "broken objects". (broken objects are objects where the
meta_type isn't recognized).

I once exported some simple objects in a Zope 2.3.0 and got the same import
error in Zope 2.3.3 like you had.
So I tried to import it programmatically from an External Method and that
worked.

I don't know why it worked but I have a qualified guess.
External Methods don't give a damn about Zope security and there is a
difference in the security in Zope 2.3.0 and Zope 2.3.3

so, create a function:

def importit(self,name):
     self.manage_importObjects([name])
     return "done"

and create an External Method to this and run.

Good luck,

Peter
