Now I am using vaadin framework and i developing statistical report tool, i have updating data from back end database, Then i am going refresh page. But is not value change . so am i going to try the refresher add on concep,t this is thread concept this application is may be affect are slow in future. ANY IDEA PLZ LET ME KNOW(just i want refresh page and get data from database from my UI) .
Vaadin is stateful and will return the old state when the user hits the refresh button of the browser. You can for example do a refresh button inside your application, that will replace the view with an updated version of it or go through all the components and reload data there. If you use the Refersher add-on instead, then just do the same logic you would do inside the clicklistener of the button, inside a refreshlistener.
