Vaadin - "new Link()" - single page loading?

Question

Java

It seems the problem is trivial, but what I don't try. Something doesn't work.

<vaadin.version>6.8.2</vaadin.version>

I am loading a list with links and when I click on the link I want to get a separate page, while on this separate page I want to make the “Back” button.

I'm looking for something and I can't find a suitable example.

They suggested an approximate code for Vaadin 7.

Page.getCurrent().addUriFragmentChangedListener(new Page.UriFragmentChangedListener() {
    @Override
    public void uriFragmentChanged(Page.UriFragmentChangedEvent e) {
         System.out.println("fragment changed: " + e.getUriFragment());
    }
});


new Link("click me!", new ExternalResource("#asdf"))

Share a piece of code for Vaadin 6.

Thank you!
