我的应用程序包含Google地图，区域图和包含列表的手风琴。当在列表中选择被改变时，该应用程序从所述服务器获取数据，并更新图和地图，重新定位地图可以包含其视口内的所有标志物和开球一个SeriesEffect动画图表数据重绘。
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将消失。

预期的行为是标签应该始终呈现。
我尝试在validateNow()上使用dataChange;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Label上;使用Flex Framework ToggleButton ChangeWatcher更新Label.text上的dataChange;重写setStyle()，以确保没有undefined值被传递到样式属性，getCurrentRendererState()，以确保状态设置为我所覆盖的状态，而updateDisplayList()到尝试在更新时设置Label颜色。
即使在重绘完成后，Label仍然会消失并且仍然缺失。选择和取消选择项目时，填充会正确更改。有没有人遇到过这个问题和/或任何人都可以想出一个我尚未尝试过的解决方法吗？
提前致谢...
答案 0 :(得分：2)
在应用程序的某处调用下一个代码（即initializeHandler）：
TextLineRecycler.textLineRecyclerEnabled = false;
这将解决问题。
答案 1 :(得分：0)
includeIn node ItemRendererLabel属性
getCurrentRendererState()并返回准确的状态字符串，因为ItemRenderer会返回更多状态字符串。答案 2 :(得分：0)
尝试在复杂组件上等待updateComplete（）事件，然后在“消失”元素上验证validateNow（）。
