Florian, this is a question about using Zope 3, so please continue this
discussion on zope3-users (I'm cc-ing zope3-users).
Now for your problem:
* Containers manage the names of objects, not the objects themselves
* __name__ is just a convention of the location/contained machinery.
* Container name choosers can choose names for your object when you
*add* it to the container. Name choosers don't play a role in edit
forms. If you would like an example of a Name Chooser adapter, please
refer to the examples in my book (they're downloadable on worldcookery.com).
* If you want to rename the object from within an edit form, you want to
introduce a second schema that looks just like the object's schema but
has an additional __name__ field (TextLine() with the appropriate
constraints regarding special characters like '/' etc.). In an adapter
from that schema to your actual schema you can do the renaming according
to changes of __name__. Note that the form redirects the browser to
itself (I think) which won't work anymore.
