[Zope] Can't import objects ... is transparent folder still the reason ?

[Didier Georgieff]

I have a problem importing objects (Yihaw Folder derived from Object Manager) on 
2.2.4 and Transparent Folder (see traceback at the end).

Some months ago i had some similar problem with the first/removed Transparent 
Folder version.
Is this same problem still there on Transparent Folder 0.3, or do i have to search the 
problem elsewhere for a workaround ?

Any idea about a temporary workaround for importing such objects ? Because it will be 
quite difficult to transfer things from developpement server to production server.
This is what Shane respond to this earlier problem. I was not able to see if TP0.3 is 
now ObjectManager safe or not.

This is the new traceback :
