The EM you receive from @PersistenceContext is container-managed whereas the EM
from Component.getInstance() is Seam-managed scoped to the conversation
context.

Got it. I thought @PersistenceContext and @In were equivalent if I declared the SMPC in components.xml.

Felix, I posted before seeing your reply. I'm confused. What's not SMPC about it?

I found that if instead of using the injected entityManager, I use the one
returned by:
(EntityManager) Component.getInstance ("entityManager");
then it works for some reason...

[jboss-user] [JBoss Seam] - Re: Seam 1.3.0.ALPHA entity converter: The instance was not
Hi Pete,
Thanks for the quick reply. I am using SMPCs, and I made all the config
changes specified in the Seam 2.0 Migration Guide in Fisheye.
Aren't all requests wrapped in a temporary conversation? At any rate, I am
inside a long running conversation. Originally, I was making the
itemTextDAO.getTutorialCategories call from inside a SFSB with
ScopeType.CONVERSATION and outjecting it. Then I made it a member (with a
get/set) of that same SFSB instead of outjecting. All with the same outcome.
Here's the entity query in a conversation scoped SFSB:
| @Stateful
| @Name("tutorialEditAction")
| @Scope(ScopeType.CONVERSATION)
| public class EditActionBean implements EditAction, Serializable {
|
| @PersistenceContext(type=PersistenceContextType.EXTENDED)
| private EntityManager entityManager;
|
| @Logger
| private Log log;
|
| private List tutorialCategories;
|
|
| @Create @Begin(join=true)
| public String create() {
| return "created";
| }
|
| @Begin(join=true)
| public String begin() {
| log.info ("Inside tutorialEditAction.begin");
| return "begin";
| }
|
| public List getTutorialCategories() {
| log.info ("Begin tutorialEditAction.getTutorialCategories()");
| if (this.tutorialCategories == null) {
| try {
| Query query = entityManager.createQuery (
| "select it from ItemText it
where it.itemCode.itemCodeType.name=:name and it.locale=:locale order by
it.text asc");
| query.setParameter ("name",
ItemCodeType.ItemCodeTypeEnum.TUTORIAL_CATEGORY);
| query.setParameter ("locale",
Locale.US.toString());
| this.tutorialCategories = (List)
query.getResultList();
|
| } catch (NoResultException ex) {
| this.tutorialCategories = new
ArrayList(0);
| }
|
| }
| log.info ("End tutorialEditAction.getTutorialCategories()");
| return this.tutorialCategories;
| }
| public String getCategory() {
| return "Application";
| }
| public void setCategory(String value) {
| }
| @End
| public String save() {
| log.info("Inside tutorialEditAction.save()");
| return "saved";
| }
|
| @Destroy @Remove
| public void destroy() {}
|
| }

Use an SMPC and make sure you are in a conversation. If you are stateless this is fine. It's when you are in session scope its harder.

[jboss-user] [JBoss Seam] - Re: Seam 1.3.0.ALPHA entity converter: The instance was not
I'm getting this one too, in code that worked in 1.2.1.GA. (I already voted in
Jira). I'm trying to upgrade to Seam 2.0.BETA1 and AS 4.2.GA.
I removed all outjection, and stripped it down to the following simple usecase:
I have a stateless session bean that returns a list of entities, which are then
immediately used to populate a selectOneMenu.
Bean:
| @Stateless
| @Name("itemTextDAO")
| public class ItemTextDAOBean implements ItemTextDAO {
|
| @PersistenceContext
| EntityManager entityManager;
|
| public List getTutorialCategories () {
|Query query = entityManager.createQuery (
| "select it from ItemText it where
it.itemCode.itemCodeType.name=:name ");
| query.setParameter ("name", "TUTORIAL_CATEGORY");
| return (List) query.getResultList();
| }
| }
|
|
html:
|
|
|
|
|
|
|
I then get the same exception /stacktrace that Felix did.
Any ideas for a workaround would be greatly appreciated, or else I'll have to
give up on upgrading for now...
thanks,
Al

[jboss-user] [JBoss Seam] - Re: Seam 1.3.0.ALPHA entity converter: The instance was not
Also, I have a quick question- would it be as simple as changing the PersistenceProvider.instance().getId() to do the same thing as the default getId() implementation (Entity.forClass( bean.getClass() ).getIdentifier(bean)) rather than delegating to Hibernate? Or will I run into further TransientObjectExceptions later on?

[jboss-user] [JBoss Seam] - Re: Seam 1.3.0.ALPHA entity converter: The instance was not
This a big step backwards in my opinion. I have a similar situation to the above, although my factories were for application scope, not even at the user session level. Now to populate these select boxes I will have to hit the DB over and over. I guess the "widest" scope I can cache these now will be at the conversation level. I'll give that a go. Did Felix create a JIRA, or would you like me to? thanks, Daniel. "petemuir" wrote : Yeah, the way I reimplemented it requires that the entities you feed to the entityconverter are managed.
