        exactly same problem here.

        I guess it has something to do with that filter: org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:176)

        Have you solved it on a way or another?

        thanks

        sure, and there are good reasons to use the OutputStream at this place, else you cant deliver a binary content without damaging it.
        Hmmm, and I cant see that we requrest the writer before .... maybe you are able to debug where getWriter() will be called?

        I'm reducing this to "Critical", as this happens only on one platform.

        Additionally, I have been submitting some changes to the ExtensionFilter (by Mike Youngstrom and others) which might have improved this situation. Can you try out with a recent version?

        regards,

        Martin
