Newbie conversation question
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()));
}
}
This is the facelets fragment for the navigation bar

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.
