Vaadin Push feature

I've ran into a strange problem using Vaadin. In my application I need to dynamicly push new data to the table viewed by the user. I've done some reading and it seems that I could achive just that with Vaadins' @Push feature.

But as soon as I've added the @Push annotation to my UI class everything stopped working. What I mean by this is I'm getting that message when accessing the UI

Session Expired. Take note of any unsaved data, and click here or press ESC key to continue.

clicking on the message just refreshes the whole page. I'm using Vaadin 8.0.6 and vaadingSpring 2.0.1, as well as Spring Boot 1.5.3

Does anyone know how to solve this?

Oh, I almost forgot. I've used this code as an example https://github.com/peholmst/vaadin4spring/blob/master/samples/push-sample/src/main/java/org/vaadin/spring/samples/push/PushUI.java

I found Push (with Spring) hard to configure. It was my fault, for sure, but I finally decided to drop it in favor of this simple extension which implements a client-based polling: https://vaadin.com/directory#!addon/timerextension-add-on
