That config seems to work, looking at a dumped $form, so the problem
must either be a misunderstanding of how it's meant to work, or a bug.
Note that the when() doesn't yet support nested params, such as "foo.bar".

Can you write a failing test file, that demonstrates what you expect
to happen, to help start to narrow it down?
