Igor, You made it very clear why a converter isn't appropriate. And also why you shouldn't use a Validator when you don't want to force the user to enter uppercase.
But what's your opinion about using an UpperCasingModel ? Downside of overriding getInput is that you'd have to do it on TextField, PasswordTextFiled, RequiredTextField, AutoCompleteTextField, ... Or am I missing something ?
