> Steps to reproduce:
> 1. Create a component that extends SkinnableContainer
> 2. Create one skin with <Group id="contentGroup" />
> 3. Create another skin class with <VGroup id="contentGroup" />
> 4. Toggle between the skin classes during runtime
>  
>  Actual Results:
> The following runtime error is shown:
> Error: You are not allowed to change the layout for this class.  It is read-only.

>  
>  
>  Expected Results:
>  I would expect that changing the content group's container from Group to VGroup to Group, would not cause a runtime error. The container, I suppose, should be reinstantiated.
>  
>  Workaround (if any):
>  In both skin classes, use <Group> component and change the layout using <layout><VerticalLayout /></layout>
