As others already pointed out: the easiest solution would be to
use a fixed Zope 2.8.x version.
Alternatively, you could fix Zope 2.8.1 yourself. For this, I added
(in our local copy) in ".../Products/PluggableIndexes/common/UnIndex.py":
# DM 2005-08-25: compatibility
from ComputedAttribute import ComputedAttribute
...
# DM 2005-08-25: backward compatibility -- overridden at instance level
def _length(self):
length = self._length = BTrees.Length.Length(len(self._index))
return length
_length = ComputedAttribute(_length)
The second hunk can go (e.g.) after the definition of "__len__".
