Change language of title of required fields dynamically.

Is there a way to change the language of a vaadin input field on run time. Setting an input field required enables a title that gets shown on hovering over the field. This title automatically uses the local of the client. Is there a way to change this on runtime for a app that uses multiple languages? A work around would be to set an own title for every required field but Session wide change of the language would be easier and faster to implement for larger apps.
