>          Components: JSF Integration
>    Affects Versions: 2.1.1.CR1
>         Environment: Mac OS X 10.5.5
> JBoss AS 4.2.3.GA
> JBoss Seam 2.1.1.CR1
> Java 6
>            Reporter: Kenneth Christensen

> Seam 2.0.3:
>       private void init()
>       {
>          // Make sure we are using the correct ClassLoader
>          originalClassLoader = Thread.currentThread().getContextClassLoader();

>          FacesContext facesContext = FacesContext.getCurrentInstance();

>          // Create a new UIViewRoot
>          originalViewRoot = facesContext.getViewRoot();
>          UIViewRoot viewRoot = new UIViewRoot();
>          viewRoot.setRenderKitId(facesContext.getApplication().getViewHandler().calculateRenderKitId(facesContext));
>          viewRoot.setViewId(viewId);
>          viewRoot.setLocale(originalViewRoot.getLocale());
>          facesContext.setViewRoot(viewRoot);
>       }
> Seam 2.1.1.CR1:
>    private void init()
>    {
>       request = new MockHttpServletRequest(HttpSessionManager.instance());
>       response = new MockHttpServletResponse();
>       
>       // Generate the FacesContext from the JSF FacesContextFactory
>       originalFacesContext = FacesContext.getCurrentInstance();
>       facesContext = RendererFacesContextFactory.instance().getFacesContext(request, response);
>       DelegatingFacesContext.setCurrentInstance(facesContext);
>       
>       // Create the viewRoot
>       UIViewRoot newRoot = facesContext.getApplication().getViewHandler().createView(facesContext, viewId);
>       facesContext.setViewRoot(newRoot);
>       
>       // Set the responseWriter to write to a buffer
>       writer = new StringWriter();
>       facesContext.setResponseWriter(facesContext.getRenderKit().createResponseWriter(writer,
>       null, null));
>    }
> As you can see, Seam 2.1.1.CR1 never checks for the original FacesContext, but creates a new FacesContext which includes the MockHttpServletXXX.
> It's a problem for the application I'm developing, because I need the external context (HttpServletResponse) when I'm using the renderer.render("/abc/xyz.xhtml").
> It works fine with Seam 2.0.3, but not with Seam 2.1.
