FacesContext.getResponseStream/getResponseWriter unimplemented
--------------------------------------------------------------
Key: MYFACES-605
URL: http://issues.apache.org/jira/browse/MYFACES-605
Project: MyFaces
Type: Bug
Components: Implementation
Versions: Nightly Build
Reporter: Mike Kienenberger
I'm trying to generate a downloadable file link, and I'm using:
FacesContext facesContext = FacesContext.getCurrentInstance();
OutputStream responseStream = facesContext.getResponseStream();
but responseStream is coming back null.
A search through the code seems to indicate that the only thing to call
ServletFacesContextImpl.setResponseStream is
FacesContextWrapper.setResponseStream(), and nothing calls this method.
The same thing appears to be true for responseWriter.
It looks like these methods should be delegating to the ExternalContext rather
than holding local copies of the values, especially since the external context
has valid references.
facesContext= ServletFacesContextImpl (id=117)
_externalContext= ServletExternalContextImpl (id=122)
_servletResponse= ExtensionsResponseWrapper (id=157)
printWriter= null
response= ServletHttpResponse (id=165)
stream= ByteArrayOutputStream (id=167)
_renderResponse= false
_responseComplete= false
_responseStream= null
_responseWriter= null
However, I'm not sure the best way of doing this. One way would be to
typecast ExternalContext to either a ServletExternalContextImpl or a
PortletExternalContextImpl and follow the chain of objects.
I can create a patch to do this if there's confirmation that this is the best
way to go about it.
