Updating page from server-side

Hai! I have a problem. I want to update page (separate part) from server-side. Now I make a change on the server side, but that they reflected on the client side, he has to click on a certain item.

Hi, have you enabled server push?

Basically add vaadin-push dependency, annotate UI class with @Push and perform operations with UI.access when updating from a background thread

See https://vaadin.com/docs/-/part/framework/advanced/advanced-push.html for detailed explanation
