Can someone please clearify the relation(s) between Root and Application?Each Root has exactly one Application?Why can an application have more than one root objects?
Do those relations have any meaning/impact on window handling?
Each browser tab, portlet etc. of a single application maps to a Root.
In Vaadin 7, multi-tab support is enabled by default so new Roots are created when navigating to the application on different browser tabs etc.
