View parameter when navigating to another page

Question

I am using JSF2, and I need to be able to pass a parameter from one JSF page to another via a commandLink.

I am on page funding.xhtml (ViewScoped) and h

Answer 1

Use and :

Source page:

Destination page (bound):

Destination page (unbound):

Backing bean (only if you want to bind the param):

@ManagedBean
@ViewScoped
public class DestinationBacking{
    String fromPage;

    public String getFromPage(){
        return fromPage;
    }

    public void setFromPage(String frompage){
        fromPage = frompage;
    }
}

Your view path will be binded to fromPage property from the destination backing bean and after you can use it to return to the original page.

Also I want to say that this way is a bit 'hackeable' by the end user, I mean, you're passing the original path through pure url. See also other ways to achieve that, as flash scope, which is very useful specially if you're working with @ViewScoped beans.
