hi,
please point me to an example showing how to use ObjectWidget with a
default add form. in case there is no example, perhaps my failing
attempt below could serve as one, once it's modified to work.

and configure.zcml as listed below. in the zmi, i add a Limoservice ok,
then i enter that container and see car and driver in my add menu, and i
add a car ok, but when i try to add a driver, i get this error:
