AS3清单问题

Question

我想添加一个List对象动态阶段，但我总是当某一行被称为一个错误：

input.addItem({label:"test",data:"test"});

错误在运行时引发：

TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/addChildAt()
at fl.controls::BaseButton/fl.controls:BaseButton::drawBackground()
at fl.controls::LabelButton/fl.controls:LabelButton::draw()
at fl.core::UIComponent/drawNow()
at fl.controls::List/fl.controls:List::drawList()
at fl.controls::List/fl.controls:List::draw()
at fl.core::UIComponent/fl.core:UIComponent::callLaterDispatcher()
TypeError: Error #2007: Parameter child must be non-null.

at fl.controls::BaseButton/fl.controls:BaseButton::drawBackground()
at fl.controls::LabelButton/fl.controls:LabelButton::draw()
at fl.core::UIComponent/fl.core:UIComponent::callLaterDispatcher()

任何人有任何想法如何解决这一问题？感谢您的帮助。
