Question

将flex 3.5的应用程序迁移到flex 4.5时遇到问题。在应用程序中设置样式时，char样式无法正确应用，它仍然使用columnChart默认样式。但是当我将fx：Style声明移动到ColumnchChartModule时，char样式起作用。有人可以帮我解释为什么样式继承被破坏了吗？

BTW：当我在应用程序中定义按钮样式时，按钮样式似乎有效。

以下是我的测试代码：

在您的模块上，即。 MyCustomModule.mxml放置此覆盖代码。

override public function get moduleFactory():IFlexModuleFactory{
 return FlexGlobals.topLevelApplication.moduleFactory;
}

当模块包含图表时，Flex样式继承问题
