T5: accessing parameters from request

Hi,

I have a standard form that has an action to call BeforeProc, where email
can be accessed from request, but when BeforeProc returns "AfterProc",
the request.getParameter("email") is null, why?


	public class BeforeProc {

	    @Inject
	    private Request request;

	    Object onActivate() {
	        return sub_proc();
	    }
	
	    Object sub_proc() {
	        String email = request.getParameter("email");
			// email has value
	        return "AfterProc";
  		}
	}



	public class AfterProc {

	   	@Inject
	  	private Request request;

	    Object onActivate() {
	      	String email = request.getParameter("email");
			// email is null here
	    }

	}

sub_proc() is returning "AfterProc", which will resolve simply to the
page as is with no parameters. If you want to pass parameters to
AfterProc page the sub_proc should return a Link with the email added as
a query parameter.
