If I instead of item.getModel() for the Check, uses some PropertyModel that
evaluates to a String identifier it works fine, but then only the identifier
is saved, and not the object, which as I understand it should be the
purpose. I haven't looked at the code, but I wander what uuid is exactly as
the equals apparently fail on non basic types. Will have a look when I get
the time. Thanks for the hint.
