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.
