当SectionStackSection中的动画多于一个项目时，动画在SectionStack中不起作用

Question

我使用此代码
    

    SectionStack sectionStack = new SectionStack();
    sectionStack.setVisibilityMode(VisibilityMode.MULTIPLE);
    sectionStack.setWidth100();
    sectionStack.addSection(createGenerallSettingsSection());
    sectionStack.addSection(createIntegrationSettingsSection());
    sectionStack.setAnimateSections(true);


private SectionStackSection createGenerallSettingsSection() {
    SectionStackSection section = new SectionStackSection("General settings");
    section.setExpanded(true);
    section.setResizeable(false);
    section.setItems(getTimeoutField().view());
    return section;
}

private SectionStackSection createIntegrationSettingsSection() {
    SectionStackSection section = new SectionStackSection("Integration");
    section.setExpanded(true);
    section.setResizeable(false);
    section.setItems(getUrl().view(), getUser().view(), getPassword().view());
    return section;
}

然后动画在“常规设置”部分工作，不在“集成”中工作。 也许有人知道如何解决这个问题？
