LazyInitializationException

[drapierwim]

As you can see I'm having a LazyInitializationException error that I can't seem to fix.

First of all this stuff worked before just fine a couple months ago, the only thing changed is that I now use jBPM pageflow

Here is a piece of my faces.config

<lifecycle>
 <!--phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener-->
 <!--phase-listener>org.jboss.seam.jsf.SeamTransactionManagedPersistencePhaseListener</phase-listener-->
 <phase-listener>org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener</phase-listener>
 </lifecycle>

Here is the web.xml

<filter>
 <filter-name>Seam Exception Filter</filter-name>
 <filter-class>org.jboss.seam.servlet.SeamExceptionFilter</filter-class>
 </filter>

 <filter>
 <filter-name>Seam Redirect Filter</filter-name>

 </filter-mapping>

My statefullbean

@Stateful
@Name("accountsManager")
@Scope(ScopeType.CONVERSATION)
@Conversational(ifNotBegunOutcome="home_page")
public class AccountsServiceBean implements AccountsService, Serializable {

 private static final Logger log = Logger.getLogger(AccountsServiceBean.class);

 @PersistenceContext(type=PersistenceContextType.EXTENDED)
 private EntityManager em;

 @DataModel(scope=ScopeType.PAGE)
 private List<Account> accounts;
 @DataModelSelectionIndex
 private int accountIndex;

 @Out(required=false, scope=ScopeType.PAGE)
 private Account bookAccount;

 private boolean lookupMode;

 public boolean isLookupMode() {
 return lookupMode;
 }

 private void setLookupMode(boolean lookupMode) {
 this.lookupMode = lookupMode;
 }

 public Account getAccount() {
 return bookAccount;
 }

 @Create
 public void create() {
 log.info("created");
 }

 //@Begin(join=true)
 @Factory("accounts")
 @SuppressWarnings("unchecked")
 public void load() {
 accounts = em.createQuery("from Account a " +
 "where a.number between 1 and 7")
 .getResultList();
 }

 public void find(){
 setLookupMode(true);
 load();
 }

 public void getChilderen() {
 bookAccount = accounts.get(accountIndex);
 accounts = ((SummaryAccount)bookAccount).getChildAccounts();
 }

 public void addNew() {

 }

 public void delete() {

 }

 @Begin(nested=true)
 public String lookup() {
 setLookupMode(true);
 find();
 return "accounts_page";
 }

 @End
 public void select() {
 setLookupMode(false);
 bookAccount = accounts.get(accountIndex);
 }

 @Destroy
 public void destroy() {
 log.info("destroyed");
 }

[drapierwim]

I've read the doc and made some changes... with no success

added in the web.xml

<context-param>
 <param-name>org.jboss.seam.core.init.managedPersistenceContexts</param-name>
 <param-value>accountingDatabase</param-value>
 </context-param>

 <context-param>
 param-name>bookingDatabase.persistenceUnitJndiName</param-name>
 <param-value>java:/EntityManagerFactories/accountingData</param-value>
 </context-param>

changed my bean

//@PersistenceContext(type=PersistenceContextType.EXTENDED)
 @In(create=true)
 private EntityManager accountingData;

[drapierwim]

Thanks to my servers log file and the issues example project I've come a step closer.
Seems now I'm stuck with this

[gavin.king]

Have you set jboss.entity.manager.factory.jndi.name in persistence.xml?

[drapierwim]

Have you set jboss.entity.manager.factory.jndi.name in persistence.xml?

This is my entry in the persistence.xml

<property name="jboss.entity.manager.factory.jndi.name" value="java:/accountingEntityManagerFactory"/>

The value only references a context-param in my web.xml

<context-param>
<param-name>accountingDatabase.persistenceUnitJndiName</param-name>
<param-value>java:/accountingEntityManagerFactory</param-value>
</context-param>

But I don't understand what should reference the param-name.

[drapierwim]

I've found the problem the param-name was wrong in the web.xml instead of accountingDatabase.persistenceUnitJndiName it schould be entityManager.persistenceUnitJndiName.

But after a quick test I still got

08:58:03,473 ERROR [LazyInitializationException] failed to lazily initialize a collection of role: be.drapier.domain.SummaryAccount.childAccounts, no session or session was closed
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: be.drapier.domain.SummaryAccount.childAccounts, no session or session was closed

[gavin.king]

Use

@In(create=true)
EntityManager entityManager

For Seam-managed EMs.

[drapierwim]

Ok I'm kind of stuck here... so I will do my best to explain.
I've read in the seam documentation the following

Seam completely solves the problem of unwanted LazyInitializationExceptions, while working around the biggest problem in the open session in view pattern. The solution comes in two parts:

* use an extended persistence context that is scoped to the conversation,
instead of to the request
* use two transactions per request; the first spans the beginning of the
update model values phase until the end of the invoke application phase;
the second spans the render response phase

I migrated to a jBPM by using a pageflow definition, this makes use of MULTIPLE SFSB in these SFSB there are @Begin and @End annotations.

Since a pageflow is a conversation itself I think that these LazyInitializationExceptions occur because I'm still using the @Begin and @ End annotations. I'm I right here?

So a solution for this could be to create ONE SFSB that covers the whole proccess that uses the pageflow definition or by using the nested=true property for the @Begin annotation in all my SFSB.

What exactly opens and closes a session?

[gavin.king]

As long as you are injecting the Seam-managed EPC, and not an EJB-container-managed EPC, and as long as you remain in a single conversation, you will not get an LIE. It does not matter how many SFSBs you have. Of course, as soon as you @End the conversation, you can get an LIE.

[wquraishi]

One thing I discovered is if you override the toString() method and output the relationships, it'll force the container to load the relationship related fields. I'm thinking it accomplishes the same thing as fetchtype.eager but i've had more luck with this. Plus it works dual fold since I use the toString() method in conjunction with facesMessages to display what the object coming back is.
