The following code in DOMPartialViewContext is not rendering the "id" of the <update> element correctly for JSF 2.2:

{code}
    private void renderState() throws IOException {
        // Get the view state and write it to the response..
        PartialResponseWriter writer = getPartialResponseWriter();
        writer.startUpdate(PartialResponseWriter.VIEW_STATE_MARKER);
        String state = facesContext.getApplication().getStateManager().getViewState(facesContext);
        writer.write(state);
        writer.endUpdate();
    }
{code}

The "id" of the update should be namespaced like this:

{code}
<partial-response>
<changes>
<update id="A4673:javax.faces.ViewState:0">
<![CDATA[4212726618426443884:8310815191568508735]]>
</update>
</changes>
</partial-response>
{code}

But instead, it looks like this:

{code}
<partial-response>
<changes>
<update id="A4673:javax.faces.ViewState:0">
<![CDATA[4212726618426443884:8310815191568508735]]>
</update>
</changes>
</partial-response>
{code}

In order to see how Mojarra does it, please refer to {{com.sun.faces.context.PartialViewContextImpl.renderState(FacesContext)}} and {{com.sun.faces.util.Util.getViewStateId(FacesContext)}}.
