Description

IHeaderResponse should have a method:
public void renderOnBeforeUnloadJavascript(String javascript);

Such that you can go:
add(new AbstractDefaultAjaxBehavior() {

public void renderHead(IHeaderResponse response)

{ super.renderHead(response); response.renderOnBeforeUnloadJavascript( getCallbackScript(false).toString() ); }

protected void respond(AjaxRequestTarget target)

{ // Do stuff here. }

});
