you need to be adding the components to the form. you're currently adding them to the page itself. the component hierarchy is thus broken. on your child page, either do getForm().add(foo) [you'll need to expose a getForm method that returns the form from the parent page] or else on your parent page (BaseEditPage), setTransparentResolver(true) on the form and add the form children to the page then.
