Elements disabled after a while

Flow

Hi,

I get a problem in my Vaadin application when the computer goes in sleep mode. When I come back on the screen, every single element are disabled. Buttons are not clickable anymore and labels are disabled.
I have no idea what causes this and I don’t find any similar topic with the same problem on the web.
Does anyone have an idea ? A method I don’t know which prevents Vaadin from disabling everything after an amount of time being inactive ?

No idea ? Anyone ?

If your application is running Vaadin 7/8, it will obviously stop working once the connection to the server is dropped and session invalidated. The client-side code, however, should display a notification in this case with a suggestion to “Save changes and reload the page”. Do you have any custom styling that might hide that modal popup?
