Roadmap using HTMLB?

[Former Member]

Hi

When developing in HTMLB/JSP, is is possible to make a roadmap(or something similar), like you can do in WebdynPro?

thanks

Hi Dmitry

Thanks for your answer, but the problem is, that the text beside the "buttons" should be localizisable, and the roadmap resizable

I was hoping for a standardcomponent

Best regards

Hi Peter,

With HTMLB you will need to implement a state machine which will look something like this

public class Controller extends PageProcessorComponent{

   public DynPage getPage() {

	return new MyDynPage();
    }
	
    public class MyDynPage extends JSPDynPage{
                private int state = 0;

        public void doProcessBeforeOutput() throws PageException {
                   switch(state){
                   case 0:
                      setJspName("page0.jsp");
                   break;
                   //...
                   case N:
                      setJspName("pageN.jsp");
                   break;
  

                   }
        }

        public void onStep0(Event event) {
                state=0;
        }

        public void onStepN(Event event) {
                state=N;
        }


	public void onBack(Event event) {
			
		state--;
	}			
		
	public void onNext(Event event) {
			
		state++;
	}        
   }
}

In the JSPs you will need to surface buttons/images with onClick referring to on...(Event event) methods listed above. Also you will need to save the state, I'd propose to put it on servlet request in

doProcessBeforeOutput()

componentRequest.getServletRequest().setAttribute("state", new Integer(state));

surface as

<input type="hidden" id="state" name="state" value="<%=state.toString()%>">

get back and analyze in

doProcessBeforeOutput()

String state = componentRequest.getParameter("state");

Best regards,
