I used Fragments in another area which made the code simpler. I went from...
WebMarkupContainer loggedIn = new WebMarkupContainer("loggedIn");
loggedIn.setVisible(hasUser);
add(loggedIn);
WebMarkupContainer notLoggedIn = new
WebMarkupContainer("notLoggedIn");
notLoggedIn.setVisible(!hasUser);
add(notLoggedIn);
... to ...
add(new Fragment("description", hasUser ? "loggedIn" :
"notLoggedIn", this));
... which is quite simpler.
