as far as I can tell from a quick read of your models and questions,
this will give you what you want.
<field-list: fields="registrations">
<registrations-view:>
<input-many>
<field-list fields="prices">
<prices-view:>
<select-many/>
</prices-view:>
</field-list>
</input-many>
</registrations-view>
</field-list:>
