Check this ticket out :


Someone else also opened a ticket:


The second one I added comments to.

To quote the first ticket, here's the fix I found  :


Raphael Ritz posted this in many places and it seems to work:

         site = app[<your plone id>] tt = site['portal_types']

then call on each folder in a loop (See plone setup list for Raphael 
Ritz and Marcel MAre's postings of scripts) :

         tt['CMF Folder']._finishConstruction(f)

but, and this is my patch to Raphael Ritz's fix, also do

         tt['Large Plone Folder']._finishConstruction(site['Members'])

Because the fixes posted didn't do the Members folder.

I think if this code is put into the migration code, this bug will be 
completely fixed.

As for why these folders were screwed in the first place, it looks like 
bugs in previous versions of Plone that have now been ironed out


If this fix is exactly what was put into 2.1.2 I don't understand why 
its not converting to ATBTreeFolder because it did, for us.

This fix originally relied upon first manually doing ATCT installation 
via quick installer, then CMF recatalog, version migration, type 
migration, and only then do portal_migration.

I assumed that whoever put this fix in would have, if necessary, tweaked 
the migration code so that doing those manual steps was no longer 
necessary. Maybe that was a bad and/or not communicated assumption. ;-)

There may have been some crossed wires / lack of communication here due 
to people not knowing each other, or knowing what each other has been 
doing. I am fairly new to plone, have not yet met the people 
face-to-face and am not yet at the stage where I can check in bug fixes 

As for whether it "matters" if you've got an ATFolder, I would say yes, 
because even if it has no obvious problems, you basically don't have 
data integrity , your data deviates from a "normal" plone site and could 
cause problems later.

I think help from a seasoned plone developer is needed here......
