CMFCore.DirectoryView.DirectoryViewSurrogate _objects instead of _tree?

[Alexandru Plugaru]

I've run into this problem while upgrading to Plone 4.0.9.

When I execute the migration scripts from plone.app.folder (401 script to be more specific) which moves _objects attribute BTreeFolders to _tree attribute. However DirectoryViewSurrogate still uses _objects which is rather inconsistent.

Can you describe why this is a problem? Do you see specific errors or tracebacks? If yes, please include them here.

DirectoryViewSurrogate is not a persistent object, and doesn't have a
BTree in it. Its '_objects' attribute is not part of a public API that
should be touched by that script.

I'll post the traceback and everything else into the plone trac since there is a section there specifically for migration issues.

Thank you Tres and Jens,
