Hi,
A few quick questions about the new style collections in Plone 4.2, to
check that I understand them correctly.
Unless I have missed something, old style collections are not migrated
to new style when migrating to Plone 4.2. Does someone have code that
would do that? Perhaps an add-on that I missed? If not, then I might
want to create a package for that.
I'm not aware of existing code to do this, but it would be a nice thing
to have. Perhaps it would make sense to add to plone.app.collection (as
an optional thing) instead of a separate package?
Sub collections are not possible in the new style. I guess this is
because the UI and the logic can quickly get confusing and you do not
win much over creating a second, separate collection.
Right.
I am guessing that creating a folderish version of the new style
collections should work though, allowing you to nest them. Some logic
would be needed that looks for a parent collection and combine the two
queries. That may not be good for Plone core, but are there technical
reasons why this would not be possible?
I'm not aware of technical reasons against it. I think the subcollection
feature was removed mostly because it was confusing.
