Assuming: 
// on the server
class Config ... {
    List<Language> languageList;
}
This could be simply be
.with("languageList").fire(....);  
>> I thought maybe it wasn't working because I use using the simple version of Driver.initialize(editor) instead of Driver.initialize(RequestFactory, editor)
Simple version will work!
