Панель инструментов исчезновения при прокрутке вкладки (в Codename One)

Как исчезнуть Панель инструментов при прокрутке, описано в руководстве Codename One, в разделе « Заголовок анимации »: https://www.codenameone.com/manual/components.html#title-animations-section

Код примера (взятый из приведенной ссылки) работает. Я немного изменил его, потому что мне нужно исчезнуть с панели инструментов при прокрутке вкладок, но мой код не работает. Можете ли вы помочь мне исправить это? Пожалуйста, попробуйте прокрутить «Tab 3» (это единственная прокручиваемая), которую я тестировал со скином iPhone в Codename One Simulator. Спасибо

In Westeros the seasons last for years, sometimes decades, at a time.\n\nFifteen years prior to the novel, the Seven Kingdoms were torn apart by a civil war, known alternately as \"Robert's Rebellion\" and the \"War of the Usurper.\" Prince Rhaegar Targaryen kidnapped Lyanna Stark, arousing the ire of her family and of her betrothed, Lord Robert Baratheon (the war's titular rebel). The Mad King, Aerys II Targaryen, had Lyanna's father and eldest brother executed when they demanded her safe return. Her second brother, Eddard, joined his boyhood friend Robert Baratheon and Jon Arryn, with whom they had been fostered as children, in declaring war against the ruling Targaryen dynasty, securing the allegiances of House Tully and House Arryn through a network of dynastic marriages (Lord Eddard to Catelyn Tully and Lord Arryn to Lysa Tully). The powerful House Tyrell continued to support the King, but House Lannister and House Martell both stalled due to insults against their houses by the Targaryens. The civil war climaxed with the Battle of the Trident, when Prince Rhaegar was killed in battle by Robert Baratheon. The Lannisters finally agreed to support King Aerys, but then brutally... "));

После лучшего прочтения Javadocs я нашел это возможное решение: 

ComponentAnimation title = hi.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
        for (int i = 0; i < tabs.getTabCount(); i++) {
            Component tab = tabs.getTabComponentAt(i);
            if (tab instanceof Container) {
                hi.getAnimationManager().onTitleScrollAnimation((Container)tab, title);
            }
        }
