Hi all,
I'm having some trouble migrating my customised content types, which
are subclassing ATContentTypes.
I am migrating from Plone 2.0.5 to 2.1.2, which involves a migration
of ATCT 0.2 to 1.0.3. The Plone migration went fine, but now I have to
update my customised content types. The type that causes the problem
is one based on ATFolder. When I just try to view one, I get a
KeyError: 'constrainTypesMode'
which makes sense, because this field was introduced in ATCT 1.0. So I
figured I just have to run archetypes_tool/updateSchema, but then I get
ValueError: layout must be a non empty string, got folder_listing()
(see traceback below). I did not modify anything regarding the layout
machinery in my customizations, so I'm now at a loss.
Does anybody have an idea? As you can see, it's *almost* correct, but
somehow 'folder_listing' is not returned as a string, but as something
else (a function?).
Thanks a lot for your help,
andré>
