## Troubleshooting

### Language doesn't appear in dropdown

- Verify both `fess_label_[locale].properties` and `fess_message_[locale].properties` exist
- Check that locale code is in `supported.languages` in `fess_config.properties`
- Regenerate Java classes: `mvn dbflute:freegen`
- Rebuild project: `mvn clean package`
- Restart Fess application

        // Execute
        OptionalThing<Locale> result = provider.findBusinessLocale(null, mockRequestManager);

        // Verify
        assertTrue(result.isPresent());
        Locale locale = result.get();
        assertEquals("no", locale.getLanguage());
        assertEquals("NO", locale.getCountry());
        assertEquals("NY", locale.getVariant());
