title: Holding events in Vaadin
body: <p>I have the following issue. Say, user can click on some UI component. Each click requires a lot of calculations and changes other UI components significantly, so it's extremely expensive. Order of clicks is not important.</p>
  
  <p>So it would be cool to hold event during some time, and only if there are no other events during that time, send it to server. Otherwise all events except the last one should be ignored.</p>
  
  <p>Is there a way to implement such a behaviour in Vaadin?</p>
  
  <p>Best regards, Dmitriy.</p>
