In 7.7 (beta5) there’s this new language selector for the gateway web page (top right of the page, below the ‘log out’ button).
When i try to change the language there, i get an ‘Internal error’ page. With Wicket in dev-mode there’s this error message:
org.apache.wicket.WicketRuntimeException: no set method defined for value: en on object: [WebMarkupContainer [Component id = languageselection]] while respective getMethod being getLocale
Just to make sure: this is not the new client localization, but the old property-based localization system.
