[Zope] index_object() calls give AttributeError after move from 2.7.5 to 2.8.8

[John Schinnerer]

Aloha,

I have just moved some sites with relatively simple custom products from 
2.7.5 to 2.8.8. The products enable creation, editing and cataloging of 
simple folderish objects with some properties and some contained 
objects. They are built using mxmEasyProduct.

I moved (installed) the necessary products in the 2.8.8 instance, then 
exported site root folders from 2.7.5 instance and imported them to 
2.8.8 instance, then re-cataloged the catalogs. All that went fine and 
the vast majority of everything works, except the object indexing calls 
in the products!

Now all calls in my products to any of the object indexing methods give 
an AttributeError with the method name as the ErrorValue.

For example I have an edit function that updates properties of an object 
from data in a form submission and then reindexes the object with:

self.reindex_object()

Worked fine in 2.7.5, in 2.8.8 I get this traceback:
-----------
Traceback (innermost last):
   Module ZPublisher.Publish, line 114, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 40, in call_object
   Module Products.GTIGalleryItem.GTIGalleryItem, line 52, in 
editGTIGalleryItem
AttributeError: reindex_object
-----------
...line 52 is simply the above line of code, self.reindex_object().

Likewise when adding such an object the call:

newObjId.index_object()

gives me this traceback:
------------------
Traceback (innermost last):
   Module ZPublisher.Publish, line 114, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 40, in call_object
   Module Shared.DC.Scripts.Bindings, line 311, in __call__
   Module Shared.DC.Scripts.Bindings, line 348, in _bindAndExec
   Module Products.PythonScripts.PythonScript, line 323, in _exec
   Module None, line 11, in add_GTIGalleryItem

/growingthroughit.org/galleryitems/wg>
    - Line 11
   Module Products.GTIGalleryItem.GTIGalleryItem, line 99, in 
manage_addAction
AttributeError: index_object
--------------------
...line 99 is the above code, newObjId.index_object()

Any call to someObject.unindex_object() gives an essentially similar 
AttributeError.

I have zearched zope.org and googled and I cannot find anything 
relevant...there is no mention of changes to the indexing methods in the 
CHANGES.txt files for 2.8.x or 2.7.x or anywhere else I can find.

I have installed the same mxmEasyProduct in 2.8.8 as in 2.7.5.

Any ideas welcome...why do I suddenly get an AttributeError here?

thanks,
John S.
