Hi there,
I'm getting a "org.hibernate.LazyInitializationException: illegal access to loading collection" error when trying to manipulate a data set within an entity within the PostLoad method.

This is similar to the PostLoad method convertPhotos in example http://java.boot.by/scbcd5-guide/ch06s04.html

Should this work?

Hitting the same problem.

Using spring to configure:

Code:

  <property name="eventListeners">
      <map>
        <entry key="post-load">
          <bean class="my.package.dao.PersistedEntityPostLoadListener"/>
        </entry>
...

The collection mapping:

Code:

  @OneToMany(mappedBy="accountSheet", cascade=CascadeType.ALL, 
             targetEntity=AbstractAccount.class, fetch=FetchType.EAGER)
  public Set<Account> getAccounts() {

This happens when I iterate over the collection from the post-load listener:

Code:

  26-Mar-2008 11:46:36 org.hibernate.LazyInitializationException <init>
SEVERE: illegal access to loading collection
org.hibernate.LazyInitializationException: illegal access to loading collection
   at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:341)
   at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86)
   at org.hibernate.collection.PersistentSet.iterator(PersistentSet.java:163)
   at my.package.domain.account.AccountSheet.onPostLoad(AccountSheet.java:151)
   at my.package.dao.PersistedEntityPostLoadListener.onPostLoad(PersistedEntityPostLoadListener.java:15)

Unforunately I never found a solution, I'd be interested if you find one.

Well, the only solution I have found is to make a copy of the collection in the setter and access the copied collection during the @PostLoad method. This is a total hack but it does the trick.

This is a known issue https://jira.jboss.org/jira/browse/JBAS-5474
