ScrollingStageTextInputSkin in scroller does not scroll when focus

Hi everybody,

i changed my textinput field from spark.skins.mobile.TextInputSkin to the
new spark.skins.mobile.ScrollingStageTextInputSkin to enable the
softKeyboardType. But now when i focus the textinputs (they are in a
scroller) the scroller does not scroll them over the softkeyboard like
before.
So i am not able to enter data cause they are under the softkeyboard.

Any idea?
