[Zope-dev] pre-export and post-import hooks.

Yo, I have an object for which I'd like to have pre-export and post import-hooks. After some code browsing, I found the ObjectManager api with the manage_exportObject method. overwriting this for the export looks good, but the problem is that this only works when called directly on the object, and not when you export a container of the object in question. Is there an easy solution to this problem ? Romain Slootmaekers
