Navigate to particular Views in Liferay Portlet

Hello,

I have a Vaadin (7.1.x) portlet that has different views, which where added to a Vaadin Navigator instance in the UI class.
These are:

  • MainView with name “” (the empty string)
  • View1 with name “view1”
  • View2 with name “view2”

From the Liferay navigation bar’s pulldown menu, I want to directly navigate into a view, let’s say

  • I want to have Liferay navigation menu entry labeled “View 1” that directly leads me to a Liferay page where Vaadin “view1” is displayed
  • I want to have Liferay navigation menu entry labeled “View 2” that directly leads me to a Liferay page where Vaadin “view2” is displayed

I could not find a way to accomplish that. Whatever I try, I always find myself on the MainView with Vaadin view name “” (the empty string).
