@Mauro M. E.

Hello all: I would like to know how buttons (links) are implemented in this example:

1. http://www.blackbeltfactory.com/ui#! (Main Page)
2. Cliking Button Courses&Exams on the top of page it goes —> http://www.blackbeltfactory.com/ui#!TopicList
3. Clicking Button Users&Groups it goes → http://www.blackbeltfactory.com/ui#!GroupsAndUsers
   or Clicking Button register it goes —> http://www.blackbeltfactory.com/ui#Register

a) Is this portal programed in Vaadin ? If it is ok ,
Could you write a little example code how to change Pages in this web on clicking buttons ???

The
Navigator7 add-on
is what the developers of JavaBlackBelt created for handing the navigation on the site and much more.
