ServletExternalContextImpl.redirect did not encode URL, so URL-rewriting fail

[Hanack, Leif]

Hello, 
 
I'm using Spring WebFlow (SWF) in combination with MyFaces/Trinidad. I have the 
problem that the FlowPhaseListener from SWF is calling a method that triggers 
ServletExternalContextImpl.redirect be to called.
 
ServletExternalContextImpl:
    public void redirect(String url) throws IOException
    {
        if (_servletResponse instanceof HttpServletResponse)
        {
            ((HttpServletResponse)_servletResponse).sendRedirect(url);
            FacesContext.getCurrentInstance().responseComplete();            
        }
        else
        {
            throw new IllegalArgumentException("Only HttpServletResponse 
supported");
        }
    }

The redirect method is calling a sendRedirect on the response but did not 
encode the url, so in case of URL-rewriting the jsessionid is not attached!
 
I know that this code-snipplet will solve my problem:
 
String encodedUrl = ((HttpServletResponse)_servletResponse).encodeURL(url);
((HttpServletResponse)_servletResponse).sendRedirect(encodedUrl);
 
Did not no if this is a bug. Hope it is, and my patch will be integrated:)
 
What do you think?!
 
Thanks in advance, Leif
 
 
Mit freundlichen Grüßen
