Re: [ZODB-Dev] Cached object error while upgrading Plone
Hello Martijn, Actually for DirectoryViewSurrogate (see the second paste) that is not the case since it subclasses OFS.Folder.Folder - which is persistent. Alex.

Something that is persistent is referring to the DirectoryView (or perhaps a contained skin item) where it should not. -- Martijn Pieters ___ For more information about ZODB, see http://zodb.org/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
Re: [ZODB-Dev] Cached object error while upgrading Plone
Hello Shane, I think that you're right about the persistent to non-persistent changes and vice-versa. I will try to identify the object that does this. What do you mean by removing add-ons? You mean products? And if I remove my third party products and make the objects which subclass the ATFolder broken then I will not get the necessary upgrades specific to folders right? Thanks for your input, Alex.

And maybe a theory of why this is happening. That kind of thing happens when a class changes from non-persistent to persistent or vice-versa. This may be caused by add-ons. When I do a major Plone upgrade, I first disable all add-ons temporarily and that usually does the trick. If that doesn't work, I suggest you get a list of all your add-ons and ask this question on a Plone list.
