Hi Martin,
thanks for your reply. I get the correct instance of my custom UIViewRoot,
but the encodeBegin and encodeEnd methods never get called. I need a place,
where I can access the ResponseWriter to replace it with a StringWriter
(newResponseWriter = responseWriter.cloneWithWriter(stringWriter)). In a
PhaseListener and custom ViewHandler facesContext.getResponseWriter returns
null.
Perhaps there is another way to get the rendered html content before it gets
forwarded to the client...
Do you have any ideas how I can achieve this?
TIA
