当发生大的重绘时，Flex Spark ItemRenderer标签消失。

| 我有一个带有Google地图，面积图和包含列表的手风琴的应用程序。更改列表中的选择后，应用程序将从服务器获取数据并更新图表和地图，重新定位地图以在其视口中包含所有标记，并启动SeriesEffect来动画化重新绘制的图表数据。 当用户更改选择并在重绘地图和图表时继续将鼠标悬停在列表中的项目上时，项目渲染器上的标签会消失。 项目渲染器代码如下：

预期的行为是标签应始终呈现。 我试过在
dataChange
上使用
validateNow()
；删除css中的所有状态，并仅使用css中的组件类型选择器；将样式直接放在ItemRenderer中的ѭ4上；使用Flex框架ѭ5和ѭ6来更新
dataChange
上的
Label.text
；覆盖
setStyle()
以确保没有
undefined
值传递给样式属性，,11ѭ确保状态集是我覆盖的状态，
updateDisplayList()
尝试在更新时设置
Label
颜色。 all4ѭ仍然消失，甚至在所有重画完成之后仍然丢失。当选择和取消选择项目时，填充会正确更改。是否有人遇到过这个问题，并且/或者有人可以提出我尚未尝试过的解决方法吗？ 提前致谢...

    在应用程序中的某处调用下一个代码（即initializeHandler）： 
    TextLineRecycler.textLineRecyclerEnabled = false;
    这样可以解决问题。

    尝试从
    ItemRendererLabel
    节点中删除
    includeIn
    属性 尝试覆盖
    getCurrentRendererState()
    并返回准确的状态字符串，因为
    ItemRenderer
    返回更多状态字符串。

    尝试等待复杂组件上的updateComplete（）事件，然后在\“ disappearing \”元素上等待validateNow（）。
