I think there's an error in this example: http://book.fulcrologic.com/#_use_the_component_registry shouldn't it pass state as the first argument to swap!?

I'm using the form state support in Fulcro 3.x and running into an issue where if I edit a nested form (i.e., a form in a nested component) and then hit a submit button to trigger a diff in the parent form (the parent component) it doesn't see the nested form's new props (and therefore it doesn't show up in the diff). Any advice on how to force a rerender of the parent on subform change?

is the subform declared in form-fields?
