here is the class:
class StudentDetailList(ListView):

    updater = ListProperty([])
    def __init__(self, **kwargs):
        super(StudentDetailList, self).__init__(**kwargs)

here are the adapters:

class carouselApp(App):

def callback4(instance):

    app = App.get_running_app()
    if instance.text in app.l.ids['missing'].adapter.data and instance.is_selected == False:
        newlist = app.l.ids['missing'].adapter.data
        newlist.remove(instance.text)
        #app.l.ids['missing'].adapter = SimpleListAdapter(data= newlist, cls= ListItemLabel)
        print 'newlist is:  ', newlist

the list logic is working, but the adapter assignment fails with this error: Exception: list adapter: data must be a tuple or list
