    Newbie conversation question

    Andrew Elegante Newbie

      I'm having a hard time getting seam to start conversations when I want it to. I have a series of pages that go with a type of task. Using facelets I've created a special navigation bar for each task. This bar has a series of links that can be clicked on at any time that the user is working with that type of task. A couple of the links open 'wizards' for creating new things. What I would like to have happen is that every time a user clicks one of these links a new conversation is started and the first page of the wizard opens. I've tried this a couple of different ways and haven't had much luck

      Here is my stateful wizard bean

      @Stateful
      @Name("feeProductWizard")
      public class FeeProductWizardBean implements FeeProductWizard {
      
       @Logger private Log log;
      
       @Out
       private FeeProduct feeProduct;
      
       @In
       private FacesMessages facesMessages;
      
       @In
       private FeeConfiguratonHandler feesConfigBean;
      
       @In(create=true)
       private FeeSearcher feeSearcher;
      
       @Resource(mappedName="java:/FeeEntityManager")
       private EntityManager em;
       /** Whether the product is valid or not */
       private boolean feeProductValid;
       /** The set of default assessment notes */
       private Hashtable<Integer,String> defaultAssessmentNotes;
      
       @SuppressWarnings("unchecked")
       @Create
       public void init() {
       defaultAssessmentNotes = feesConfigBean.getDefaultNotes();
       log.info("default assessment notes = " + defaultAssessmentNotes);
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.NewWizard#startNewWizard()
       */
       @Begin
       public void startNewWizard() {
       log.info("Starting new fee product wizard");
       feeProduct = new FeeProduct();
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.NewWizard#back()
       */
       public void back() {
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.NewWizard#next()
       */
       public void next() {
       log.info("next called : " + feeProduct);
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.FeeProductWizard#validateDates()
       */
       public void validateDates() {
       log.info("validating dates");
       if(feeProduct.getEndDate() != null) {
       if(feeProduct.getStartDate().compareTo(feeProduct.getEndDate()) >= 0) {
       log.debug("end date is after start date");
       facesMessages.addToControl("endDate", "#{messages.endDateError}");
       feeProductValid = false;
       }else {
       feeProductValid=true;
       }
       }else {
       feeProductValid=true;
       }
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.FeeProductWizard#isFeeProductValid()
       */
       public boolean isFeeProductValid() {
       return feeProductValid;
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.NewWizard#cancel()
       */
       @End
       public void cancel() {
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.NewWizard#destroy()
       */
       @Remove
       @Destroy
       public void destroy() {
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.NewWizard#saveNew()
       */
       @End
       public void saveNew() {
       em.persist(feeProduct);
       }
      
       /**
       * @see com.emida.intranet.fees.wizard.FeeProductWizard#setupDefaultNote()
       */
       public void setupDefaultNote() {
       FeeProductSearchConfig config = new FeeProductSearchConfig();
       config.setFeeName(feeProduct.getFeeName());
       if(feeSearcher.doFeeProductSearch(config).size() != 0) {
       log.debug("fee name has been taken");
       facesMessages.addToControl("feeName", "#{messages.feeNameError}");
       feeProductValid = false;
       }else {
       feeProductValid=true;
       }
       feeProduct.setFeeAssessmentNote(defaultAssessmentNotes.get(feeProduct.getFeeCriteriaType().ordinal()));
       }
      }

      I first tried using the s:link tag to start the wizard but for some reason I had to click the link twice before it would call the action method. The code for that was:

      <s:link id="newFeeProduct" value="[#{feesNav.createNewFeeProduct}]"
       action="#{feeProductWizard.startNewWizard()}" propogation="begin" />
      


      Here is the navigation rule from the pages.xml file.
      <page view-id="/fees/*">
       <navigation from-action="#{feeProductWizard.startNewWizard}">
       <redirect view-id="/fees/feeProduct/wizard/step1.xhtml" />
       </navigation>
      </page>
      


      In the application's current state, I can only click on the link once. The wizard is started within the current conversation but it won't start a new conversation and if I attempt to click the link again it tells me the conversation has already been started. Everything else works beautifully though.

      Thanks in advance for your help.
