Vaadin 7 Portlet browser reload


I’m currently developing a Vaadin portlet to be incorporated in liferay. It consists in a form with some input values.

public class TheClass extends UI {
	protected void init(VaadinRequest request) {


My problem is that if I perform a browser refresh through the browser icon, the form values are maintained. I would like for the portlet to be re-initialized again.

Any thoughts?
