There was the bug that the 'home' button doesn't work in connection view after login or register.
The problem is,
is not enough to render a connection view because just with that line, the handlers for overview_button would not be attached.
With the OverviewView class' render function, it works right.
Sorry this patch has a bug. I'll fix it and re-request. Until then, ignore this request.
Fix that 'home' doesn't work after login or register
now it'll works.
