Description
When I set the Locale globally in Vaadin and/or for a DateField locally, the dropdown is correctly localized but when I select a date, the formatting doesn't use my Locale but prints English weekday names. I would expect that the formatted date was also localized using the provided Locale.
example (also see attached example project datefield-bugdemo.zip)
The code
final DateField dateField = new DateField();
dateField.setLocale(new Locale("de", "DE"));
dateField.setDateFormat("EE, dd.MM.yyyy");
displays the dropdown correctly localized:
but when selected, the date is not localized anymore:
used versions
- Vaadin Framework 8.3.2
- Firefox 59.0.1
- Spring Boot 2.0.0

Research direction
Start by running the attached datefield-bugdemo.zip with Vaadin Framework 8.3.2 and reproduce the difference between the localized dropdown and the selected-date display using DateField.setLocale(new Locale("de", "DE")) and setDateFormat("EE, dd.MM.yyyy"). Trace the DateField formatting path and verify that the selected date uses the provided locale, matching the dropdown's localization.
