Hi,
I can't understand why conversation context is not deleted when method annotated as
@End is being called. Here is the code:
| @Stateful
| @Name("editSomething")
| public class EditSomething implements EditSomethingLocal {
| @PersistenceContext
| EntityManager em;
|
| @Resource
| SessionContext ctx;
|
| @In
| Context sessionContext;
|
| @In(create=true)
| @Out
| Something something;
|
| @In(create=true)
| FacesMessages facesMessages;
|
| @Begin(join=true)
| public void prepare(){
| System.out.println("prepare");
| }
|
| @End(beforeRedirect=true)
| public void create(){
| em.persist(something);
| }
|
| @Remove
| @Destroy
| public void remove(){
|
| }
| }
|
form to create:
| <h:form>
| <table border="0">
| <tr>
| <td class="cntForm">Name</td>
| <td class="cntForm">
| <h:inputText id="name"
required="true" value="#{something.name}">
| <s:validate />
| </h:inputText> *
| </td>
| <td><h:message for="name"
styleClass="cntError" /></td>
| </tr>
| </table>
|
| <h:commandButton action="#{editSomething.create}"
value="Create" />
| </h:form>
|
|
The first entity is created ok, but when then the form is displayed the input field
contains name of the created item, and when Create button pushed secnod time i'm
getting
| javax.persistence.PersistenceException: org.hibernate.PersistentObjectException:
detached entity passed to persist
|
that's clear - since context was not destroyed the entity stored in it got detached
and when again was passesed to persist causes exception. But according to seam docs
anonymous wrote :
| When an @End method is encountered, any long-running conversation context is demoted
to a temporary conversation
|
and
anonymous wrote :
| At the end of the restore view phase of the JSF request lifecycle, Seam attempts to
restore any previous long-running conversation context. If none exists, Seam creates a new
temporary conversation context.
|
Thus, if existing contex was demoted to temporary one seam should create new temporary
conversation context (and create new Something in it!) which in it's turn should be
promoted to the long running conversation when prepare() is called...
What do i miss?
wbr, eugen.
