Hi Pascal, Very cool demo ! I wish the XWiki core developers (including me) would document features that well !! This sounds really cool. I have one question:
How do you automatically upgrade an object to the latest version of a class ? I have the feeling that this could make life complex for users for the case happening most time (adding properties over time). I'm wondering if a way to handle this would be to do a merge between the class as it was when the object was last created/updated and the way it is now. Basically when you save you ask the user if he wants to "upgrade" the object of there are any changes to the class definition that go beyond adding properties or when the changes have storage impact. Now this would mean automatic upgrading if changes are only cosmetic (which could be different in some cases from the desired effects). It's great to see people dig into this part of the code.
