------------------------------------------------------------
I switched persistence context to extended and the
{{LazyInitializationException}} disappeared.
Therefore I can not reproduce the issue.
In this
[line|https://github.com/jhuska/RF-12608/blob/master/src/main/java/org/richfaces/tests/Bean.java#L21]
I am printing the class of the returned collection. The output from that line
is {{class org.hibernate.collection.internal.PersistentBag}}, which is some
kind of runtime proxy according to
[this|http://java.dzone.com/articles/jpa-lazy-loading] article, which retrieves
all entities once firstly accessed. The same apply when I am not finding the
runtime class of the list.
Ken H., could you please confirm that the behavior align with your description
? Thanks.

> Key: RF-12608
> URL: https://issues.jboss.org/browse/RF-12608
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Affects Versions: 4.2.3.Final, 4.3.0.M2
> Reporter: Ken H
> Assignee: Juraj Húska
> Labels: regression, waiting_on_user
>
> Changes to the selectManyHelper class in 4.2.3+ causes a lazy loading
> exception in hibernate when the backing collection is persistent and is not
> eagerly loaded.
> The problem seems to be that fetching the collection in
> SelectManyHelper.getConvertedValue bypasses the PersistentSet getter that
> would normally issue the lazy load request.
> Defining the collectionType (e.g. java.util.ArrayList) bypasses this issue.
> Ideally this method would detect Hibernate proxy collections and handle them
> appropriately. However, I realize that may cause a dependency so perhaps it
> would be enough to document this option and situation in the component
> reference.
