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.

Previously I got this error

To get rid of this use below code when you redirect the page

That looks like user-defined login code. I have a standard disclaimer for user-created security systems: the technical term for such things is "hacked". Or "pWned". User-designed security systems are notoriously insecure. I recommend using the J2EE standard security system instead. It has proven security, it's already installed in even the most basic J2EE servers (such as Tomcat), it's well-documented, it's already debugged, and it doesn't require special code to do most of its functions.
 
I agree. Here's the link: http://aspose.com/file-tools
