Link to URL -- How to use it?

Question

Hi Experts,
I have created LinktoURL UI element in my WD program1. I have to call WD program2 from WD program1 using this LinktoURL UI element. I had earlier written code like as below. The code was working fine. Now my problem is that code is not working any more. Can you please provide me some guidelines. What is the generaic method to call one WD program using other WD program using LinktoURL. I had created context called URL and wrote the code in wdDoModify. Problem is earlier code was working fine. Its not working now !!!
Thanks
Gary
public static void wdDoModifyView(IPrivateAutoSettlementAppView wdThis, IPrivateAutoSettlementAppView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
if(!"".equals(wdContext.currentContextElement().getTripNumber())&&null!=wdContext.currentContextElement().getTripNumber())
      wdContext.currentContextElement().
      setUrl("https://ruepd.mycompany.com:50001/irj/portal?" +
                  "NavigationTarget=ROLES%3A%2F%2Fportal_content%2Fcom.sap.pct%2Fevery_user%2Fcom.sap.pct.erp.ess.bp_folder%2Fcom.sap.pct.erp.ess.roles%2Fcom.sap.pct.erp.ess.employee_self_service%2Fcom.sap.pct.erp.ess.employee_self_service%2Fcom.sap.pct.erp.ess.area_travel_expenses%2Fcom.mycompany.portal.page.create_expense_report&DynamicParameter=trip_number%3D"+
               wdContext.currentContextElement().getTripNumber() +
               "%26mode%3Dcreate&TarTitle=Create%20Expense%20Report");
      else
           wdContext.currentContextElement().setTripNumber(wdContext.currentSettlement_DetailsElement().getReinr());

I have the same scenario and this code works very well:
change "BBAprovacoesPendentes" for your target application name.
  public void onActionAprovacoesPendentes(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionAprovacoesPendentes(ServerEvent)
       //Get component's message manager
       IWDMessageManager messageMgr = wdComponentAPI.getMessageManager();
       // Get name of deployable object this component belongs to
       String deployableObjectName = wdComponentAPI.getDeployableObjectPart().getDeployableObjectName();
       Map urlParameters = new HashMap();
       // get URL parameter value entered by user, stored in context attribute
       // u2018UrlParamValueu2019. Put parameter u2018hugou2019 in the sneak preview version.
       try {
       // Get deployable object part of target application.
       // Precondition: assume, that other application belongs to the same
       // Web Dynpro Project (Deployable Object)
       WDDeployableObjectPart deployableObjectPart =
       WDDeployableObject.getDeployableObjectPart(
       deployableObjectName,
       "BBAprovacoesPendentes",
       WDDeployableObjectPartType.APPLICATION);
       // Get target URL based on deployable object part and URL parameters 8
       String urlToTargetApp = WDURLGenerator.getApplicationURL(deployableObjectPart, urlParameters);
       // Fire exit plug to target URL via IPublic-API of used interface view
       // controller
       wdThis.wdGetRequisicaoCompraWindowController().wdFirePlugExitPlug( urlToTargetApp );
       } catch (WDURLException e) {
            messageMgr.reportException(e.getLocalizedMessage());
       } catch (WDDeploymentException ex) {
            messageMgr.reportException(ex.getLocalizedMessage());
    //@@end
