Hi, I am attempting to use Sun's jsf-portlet integration with Pluto 2.0. I get the following:

Caused by: java.lang.ClassCastException: com.sun.faces.portlet.ByteArrayWebOutputStream cannot be cast to javax.servlet.ServletOutputStream

The JavaDocs for javax.portlet.MimeResponse indicates the getPortletOutputStream() method return value is of type java.io.OutputStream. Hence the cast to javax.servlet.ServletOutputStream in HttpServletPortletResponseWrapper seems dodgy. Can you confirm if this is indeed an issue with Pluto's implementation or not?

Thanks,
Rossen
