Description

My client got an RTE at s:List#restoreCaretScrollPosition.
I could not reproduce this RTE. But I got stack trace.

TypeError: Error #1009
at spark.components::List/restoreCaretScrollPosition()
at MethodInfo-34449()
at flash.events::EventDispatcher/dispatchEvent()
at mx.core::UIComponent/dispatchEvent()
at mx.managers::LayoutManager/doPhasedInstantiation()
at mx.managers::LayoutManager/doPhasedInstantiationCallback()

I looked at the source and I guess the only reason which causes this error is dataGroup was null.
