RequestParameter is null inside Factory method

[gav_on_rails]

I'm setting a variable with the @RequestParameter annotation and then wanting to use this in a method annotated with @Factory, but finding the variable is null at this point. When the event handling method is invoked it is then populated as expected. Is this a bug? I have seen guides which claim that the request parameter values should be populated and available inside @Factory annotated methods. Here is the abridged code:

@Stateful
@Name("appController")
@Scope(ScopeType.SESSION)
public class ControllerImpl implements Controller {
        
        @RequestParameter("applicationCode")
        String applicationCode;

        @In(required = true)
        Application application;

        @Override
        @Remove
        public void destroy() {
        }

        @Override
        public void processRequest() {
           // applicationCode is not null in here
        }

        @Factory(value = "application")
        public void initApplication() {
           // applicationCode is null in here
        }

}

Try using page parameters instead - a @RequestParameter is injected from the current set of request parameters at every method invocation on your component - so if you aren't in the same request it will be null (e.g. after a redirect).
