After migrating to Vaadin7 we discovered strange forms behavior: on big forms with vertical scrollbar if you scroll bottom (or just any further from top scrollbar position) and change form field, vaadin scrolls the form up. Components are setImmediate(true), so every change produces ajax request to server. Chrome debug page (F12) shows that browser sends ajax request with “scrollTop” variable change.
I’ve made a screenshot of Vaadin debug info: https://dl.dropboxusercontent.com/u/1405291/stackoverflow/19481515-screenshot.png
How this can be fixed (so that vaadin wont scroll the form to top)?
