> When a CartesianChart is initialized with a null Axis, which can be created in the future an propagated through bindings, the chart throws RTE because the value is not validated if it's null or not.
> In AxisRenderer, 
>    public function set axis(value:IAxis):void
>     {
>         if (_axis)
>         {
>             _axis.removeEventListener("axisChange", axisChangeHandler, false);
>             _axis.removeEventListener("titleChange", titleChangeHandler, false);
>         }
>         _axis = value;
>         value.addEventListener("axisChange", axisChangeHandler,
>                                false, 0, true);
>         value.addEventListener("titleChange", titleChangeHandler,
>                                false, 0, true);
>     }
> should be 
>    public function set axis(value:IAxis):void
>     {
