[Zope-CMF] Problems with CMF 1.2/Zope 2.5.0 and a custom object that used to work fine :)

[Doyon, Jean-Francois]

Hello,

I'm migrating to the latest CMF and Zope, and ran into a problem:

I have a custom defined content object type that I added in CMFDefault
called "Map" it simply holds one property, a number that i call MapID.

All was fine in 2.4.3, but now when I move to 2.5.0, I get the following
when trying to view the object:

Error Type: AttributeError
Error Value: __getitem__

Traceback (innermost last):

The object itself is fine, I can edit it and view it in the ZMI no proble=
m,
and I actually imported a bunch from a .zexp from the prvious Zope also
without incident.

Does any one know what's going on ? I looked at the archives, but the
problems refrred to in there don't seem to be the ones plaguing me here .=
..
i think :)

Here's the code in CMFDefault that handles the object, it is my first and
only custom made content type, so forgive me if you see anything horrible=
 in
there :)

        return "%s" % (self.title)

   =20

This object is basically the core of our business, so I kind of need it :=
)

Any help would be greatly appreciated, thanks!
