You cannot sendRedirect() after ANY data has been written to the HTTP response stream. This is not a JSF limitation - it's a fundamental restriction in HTTP. And by ANY output, I mean things like the content-type header, cookies, or anything else, not just page content.

Customer surveys are for companies who didn't pay proper attention to begin with.
