To repost an earlier mail:

The patch I propose to include is:

Could some Plone folks please test that switching to
CMF/branches/efge-1.5-five-compatible instead of CMF/branches/1.5 doesn't
cause problems in Plone ? This patch just changes the order of base class
for File and Image, and to do the CMFCatalogAware recursion it calls its
base class instead of redoing it by hand.

It *has* to be tested for Plone, as I have no idea what Plone does w.r.t CMFCatalogAware monkey-patching.

i've taken a look at this, the patch definitely introduces some problems w/ Plone. the issue is that AT's BaseFolderMixin class, which is the underlying class for all of Plone's folderish content, has a declaration that looks like this:

class BaseFolderMixin(CatalogMultiplex,

CatalogMultiplex is a subclass of CMFCatalogAware which overrides the (un/re)indexObject methods to perform operations in multiple catalogs, if necessary. your patch changes CMFCatalogAware's manage_before* and manage_after* methods so that it delegates to 'super' in order to handle recursion w.r.t. containers, but in this case 'super' ends up being BaseObject, and so the manage_(after|before)* methods in ObjectManager (inherited via PortalFolder) never get called.

to be fair, AT's (un)indexing code is a mess... i tried to change the BaseFolderMixin manage_(after|before)* methods so they explicitly call the PortalFolder implementations and was still ending up w/ subobject orphans left in the catalog after container deletions. ideally, this would provide us an opportunity to push the CatalogMultiplex functionality down into the CMF core and clean up the indexing mess on the Plone side a bit. and in a perfect world, we'd defer the actual (un)indexing until the end of the transaction. those changes might be too much to try to get into CMF 1.6, however...

in any event, i'll see if i can get some help on the plone side straightening out the indexing spaghetti. we can't just start using the new code, however, w/o serious breakage. :-(.
