Does undo fire an ObjectModifiedEvent?

Last time I looked it didn't.

If not I'd guess that the
catalog will still contain pre-undo data.

For this reason and others, it is my opinion that it is usually a bad idea to expose ZODB's undo facility in applications. Applications that want to provide undo should do it another way, such as version control. ZODB undo is best left for administrative use only.
