Refresh application regardless of server changes

Vaadin 6 / 7 / 8
1

Hi,

I like to have an appliation, where every X seconds or so, the ui is refreshed. I know that there is
Ui.setPollingIntervall
, but from what I understood, that checks whether the UI has changed (e.g. a new table row added, progressbar changed etc).

In my case, I show some data and this data might have changed. So the UI it self has not changed, but when I manually reload the page, the new data is correctly fetched and displayed - and this I like to happen automatically

How can I do this in Vaadin ? (like the autorefresh option in jenkins)

Hi,

It sounds like Server Push is what you need. Take a look at the
docs
 and see if that works for you.

Hope this helps,
