Agreed

Some of the *magic* answers coming out of blogs imply the existence of knowledge that I can't find documented anywhere.

Stephan Wissel kindly noted that you cannot get the stream at all in the afterRender event, as the Domino server will have automatically enabled the Writer, and as you can only have EITHER stream OR writer active, streams are not available in the afterRender event.

I am continuing the hunt though by checking other events =)

1) No getResponseStream()
First test seems to show that facesContext.getResponseStream() has not been implemented at all.

I tried the following fragment in all events, one at a time.

print("start");
var rs = facesContext.getResponseStream();
if(rs == null) {
print("fc.getResponseStream() == null");
} else {
print(rs.getClass().getName());
}
print("end")

This prints fce.getResponseStream() == null, in all events. I don't know if this is broken or 'working as intended'

2) Getting output stream from the Response object breaks the xpage.

print("start");
var ex = facesContext.getExternalContext();
var response = ex.getResponse();
var rs = response.getOutputStream();
if(rs == null) {
print("response.getOutputStream() == null");
} else {
print(rs.getClass().getName());
}
print("end")

As you predicted, the getOutputStream() fails on the afterRenderResponse() event. On all other events I see the following:

10/05/2009 19:02:25 HTTP JVM: start
10/05/2009 19:02:25 HTTP JVM: com.ibm.xsp.webapp.XspHttpServletResponse$InternalOutputStream
10/05/2009 19:02:25 HTTP JVM: end
10/05/2009 19:02:25 HTTP JVM: SEVERE: CLFAD####E: Exception thrown
10/05/2009 19:02:25 HTTP JVM: SEVERE: CLFAD####E: Exception occurred servicing request for: /test/TestCharts.nsf/test.xsp - HTTP Code: 500
10/05/2009 19:02:25 HTTP Web Server: Command Not Handled Exception [/test/TestCharts.nsf/test.xsp]

My current theory?

The Domino server expects to get access to the Writer object, if you access the Stream object the Writer is disabled and when Domino tries to get it, instead of failing gracefully, it croaks and sends a 500 response.

There may be a magic call to stop Domino doing that but there's no doco. I will hunt through JSF stuff maybe.
