The code example seems to be outdated.

should be :

final TimerExtension timerExtension = TimerExtension.create(extendedComponent);
timerExtension.setIntervalInMs(1000);  // polling interval in milliseconds
timerExtension.addTimerListener(e -> { /* handle polling event */ });
layout.addComponent(extendedComponent);

// ...

timerExtension.start();  // start the polling explicitly, it is stopped when the extended component is detached from the UI
