> When rotating the mobile simulator (Menu Device>Rotate left or right), I get the following error:
> {code}
> Error #1056: Cannot create property null on spark.components.DataGroup.
> at spark.components::Scroller/http://www.adobe.com/2006/flex/mx/internal::snapElement()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\Scroller.as:1571]
> 	at spark.components::Scroller/checkScrollPosition()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\Scroller.as:1750]
> 	at spark.components::Scroller/handleSizeChange()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\Scroller.as:1766]
> 	at spark.components::Scroller/handleSizeChangeOnUpdateComplete()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\Scroller.as:2048]
> {code}
> In Scroller:1571     viewport[scrollProperty] = snapScrollPosition;
> scrollProperty is null, which trigger the RTE.
> Scroller belongs to a spark:List with HorizontalLayout and verticalScrollPolicy style is set to ScrollPolicy.OFF.
> also, the RTE does not seem to occur on the real device, but maybe it is just swallowed...
