    Hi,
    I think it is a stupid problem. But I do not know how it can be cracked:
    I want need the user to be able to download a file that is stored somewhere in the server.
    I found some solutions like:
    http://wiki.apache.org/myfaces/Sending_Files
    If I integrate this code in my action or actionListener method it does not works.
    The reason is that the result for the response
    HttpServletResponse response =
    ( HttpServletResponse ) context.getExternalContext().getResponse();
    is always null.
    Have anyone a tip?
    Thanks
