FPM step navigation.

Question

Hi,
We have just begun to develop applications with the FPM and we have a serious problem. We need your help.
In a roadmap with a number of steps we are not able to change perspective (and thus move from one step to the next) launching an user event (eg SELECT).
In the onEvent () method we get the event launched but the step does not change.
Anyone knows that it can be? is very rare ...
Regards.

Hi Aishwarya,
There is the entire code of my Configuration Component Interface:
public void loadConfiguration( com.sap.pcuigp.xssfpm.java.IFPM fpm )
    //@@begin loadConfiguration()
     log4j.info("Inicio del Cc Prueba: loadConfiguration");
     this.fpm = fpm;
     String dcName = "sap.com/PruebaSteps";
     String packageName = "com.ibermatica.pruebas.";
     //VACs
      VAC vac1 = new VAC(dcName, packageName  + "vc1.Vc1");     
      VAC vac2 = new VAC(dcName, packageName + "vc2.Vc2");                                                  
     //perspective composition
      VAC[] startVac = new VAC[] {vac1};     
      VAC[] selectVac = new VAC[] ;          
     //Perspectives
      Perspective startPerspective =
                         new Perspective("START", Perspective.LAYOUT_ROW, startVac);
      Perspective selectPerspective =
                         new Perspective("SELECT", Perspective.LAYOUT_ROW, selectVac);     
     // fill the perspectives
     perspectives = new HashMap();
     perspectives.put(startPerspective.getName(), startPerspective);
     perspectives.put(selectPerspective.getName(), selectPerspective);        
     //Navigation Paths
     NavigationPath start =
                  new NavigationPath("", IFPM.EVENT_START,
                                                  startPerspective.getName());
     NavigationPath toStep2 = new NavigationPath(startPerspective.getName(),
                                           IFPM.EVENT_SELECT,
                                             selectPerspective.getName());     
     NavigationPath toStep1 = new NavigationPath(selectPerspective.getName(),
                                                IFPM.EVENT_BACK,
                                                  startPerspective.getName());                    
     NavigationPath[] navigationPaths =
                    new NavigationPath[]
{start, toStep2,      toStep1};
//Navigation graph
      navigationGraph = new NavigationGraph(navigationPaths);
     //Roadmap steps
      ROPStep ropStep1 = new ROPStep(startPerspective.getName(),
                                                       "Paso 1",
                                                       null);
      ROPStep ropStep2 = new ROPStep(selectPerspective.getName(),
                                                       "Paso 2",
                                                     null);     
     //Roadmap
      ROPStep[] ropes = new ROPStep[]
                      {ropStep1, ropStep2};                                               
      ROPState rop1State = new ROPState
                                   (ropes, ropStep1.getId());     
      ROPState rop2State = new ROPState
                                        (ropes, ropStep2.getId());                                             
     //ROP States HashMap          
     ropStates = new HashMap();
     ropStates.put(startPerspective.getName(),rop1State);     
     ropStates.put(selectPerspective.getName(),rop2State);     
    //@@end
public com.sap.pcuigp.xssutils.java.CAPState getCAPState( com.sap.pcuigp.xssfpm.java.Perspective perspective )

     if(currentPerspective != null)
          log4j.info("current perspective: "currentPerspective.getName()" "+currentPerspective.getEmbeddedVACs()[0].getComponentName());
     log4j.info("event name: "+eventName);
          String currentPerspectiveName =
                  (currentPerspective == null) ? "" : currentPerspective.getName();
          String toPerspectiveName =
                  navigationGraph.getNextNode(currentPerspectiveName, eventName);
          if (toPerspectiveName == null) {
               fpm.getMessageManager().raiseException(
                       wdThis.wdGetAPI().getComponent(), null,
                       IMessageManager.DEFAULT_EXCEPTION,
                       wdThis.wdGetAPI().getComponent().getTextAccessor().getText("err_no_next_perspective"));                                        
               return null;
          Perspective toPerspective = (Perspective) perspectives.get(toPerspectiveName);
          if(toPerspective == null) {
               fpm.getMessageManager().raiseException(

    //@@begin getROPState()
     log4j.info("CcPrueba: getROPState");
     log4j.info("CcPrueba: Llega la perspectiva con estado activo: "+perspective.getName());
     ROPState ropState = (ROPState) ropStates.get(perspective.getName());
     log4j.info("ropState activo: "+ropState.getActiveStep());
     return ropState;
    //@@end
I hope this will help more.
Thank you very much for your effort Aishwarya.
Thanx¡¡
