-------------------------------------

This one remains an issue for

			<artifactId>hibernate</artifactId>

			<version>3.0.0.ga</version>
		</dependency>

We have a persistence service that implements OpenSessionInView and works.

This stack trace though is one hard to crack.

Here is the guy that causes it

Organization.JAVA operates a collection
    Organization--<>----Coach

Coach.JAVA extends from person.JAVA
    Person--<----------Coach

Organization.JAVA
	@OneToMany(cascade = CascadeType.ALL, fetch=FetchType.EAGER)
	@JoinColumn(name = "coach_organization_fk", insertable = true, updatable = true, nullable = true)
	@Collection(child = true, inverse = "organization")
	@PropertyDescriptor(readOnly = false, searchable = true)
	public Set<Coach> getCoaches()
	{
		return coaches;
	}

No fix for this exists


cannot even go near the collection

> I have an entity which can have multiple titles located in a separate table. I mapped this as a set where key attribute references other property of the entity:
> <set name="titles" table="TTitle" cascade="none" lazy="true" inverse="true" mutable="false">
> 			<key column="ID" property-ref="parentId"/>
> 			<!--key column="ID"/-->
> 			<element type="string" column="title"/>
> 		</set>
> when I try to display this set I get an exception: 
> org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: test.lazysetinit.Record.titles, no session or session was closed
> 	at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358)

> The entire mapping is as follows:
> 	<class name="Record" table="TRecord" mutable="false">

> 			<key column="ID"/>
> 			<property name="parentId" not-null="false" />
> 			<property name="status" />
