/**
* A wrapper for {@link FlowResponseStateManager} used to support MyFaces partial state saving. MyFaces supports an
* extension to the {@link ResponseStateManager} that reduces the amount of buffering required when writing a response.
* Empty state is provided at the time that the {@link #writeState(FacesContext, Object) writeState} method is invoked
* with an additional {@link #saveState(FacesContext, Object) saveState} method called later containing the real state
* to save.
* <p>
* Since JSF 2.0, the strategy used by MyFaces to determine if a {@link MyfacesResponseStateManager} is available will
* always succeed since it follows {@link FacesWrapper}s to find the root <tt>HtmlResponseStateManager</tt>
* implementation. Since state management for web flow requests is handled by the {@link FlowResponseStateManager} this
* assumption causes problems and results in empty state data being saved. This wrapper provides the additional hook
* required to ensure that the {@link #saveState(FacesContext, Object) saveState} method also triggers web flow state
* management.
