When i have a conversation that already started(by invoking method annotated with @begin, and
1.) I press back button and
2.) click on a submit button, it brings me back to the page where the current state should be, this it shows a message "Illegal navigation" this is fine, it's the page where the user should be.
3.) i click any button
However, now it bombs out. I must be doing something wrong as the tutorial had stated that free navigation is supported and handled.
Here is the exception:

here is my session bean, where "@Conversational(ifNotBegunOutcome = "registerUserPage")
" is supposed to bring the user to the appropriate jsp specified by the nav rule "registerUserPage.:
|
| @Stateful
| @Name("registerUserAction")
| @Scope(ScopeType.CONVERSATION)
| @Conversational(ifNotBegunOutcome = "registerUserPage")
|
| public class RegisterUserAction implements Register {
|
| private Users user;
|
| private String password;
|
| @PersistenceContext
| private EntityManager em;
|
| @Logger
| private Log log;
|
| @Begin(join=true, pageflow = "registerUserPageFlow")
| public void begin() {
| if(user==null){
| log.info("Start");
| user=new Users();
| }
| }
| ...........
| }
|
my jpdl:
| <?xml version="1.0"?>
|
| <pageflow-definition name="registerUserPageFlow">
| <start-state name="start">
| <transition to="emailForm"/>
| </start-state>
|
| <page name="emailForm" view-id="/register.xhtml">
