Changing the query string on postback

[averri]

I would like to change the query url after a postback.

Example: after a successful postback (a save operation) the URL must be changed from /user.jsf to /user.jsd?userId=123.

You could try a redirect.

Redirect is not postback, so redirect will not work in my case.

I'm just suggesting you follow the post/redirect/get design pattern:

Something else you could try is URL rewritting. Take a look at PrettyFaces:
