I am having problems getting server-push to work in my app. I would like to try a simple example app before trying to fix my own app. 回答1: Simplification Of Example In The Book Of Vaadin The Book Of Vaadin includes a chapter on Push, including an example using Vaadin Charts . Below is my code. While based on that Vaadin Charts example mentioned above, I simplified it by replacing the use of a Chart object with a simple Label
