You can use javascript call handlers, ex:
Wicket.Ajax.registerPreCallHandler(
function(){
window.onbeforeunload = function() {
return "There is some activity going on, please wait until
the activity indicator disappears";
};
}
);
Wicket.Ajax.registerPostCallHandler(
function(){
window.onbeforeunload = null;
}
);
