Все работает, кроме как до последней части кода с "Успешно Зарегистрирован! " тогда ошибка, упомянутая в заголовке, появляется внутри части сообщения registerDialog.

Что-то я делаю неправильно? может кто-нибудь помочь мне проверить мой код

Большое спасибо.

Приложение не "t сбой, хотя он просто выходит обратно на главную страницу приложения. и если я снова нажму кнопку регистрации, он вернется с той же ошибкой.
