Hey guys,
I tried to reproduce the issue in [this|https://github.com/jhuska/RF-12608]
project.
When accessing http://localhost:8080/RF-12608 I am getting
{{LazyInitializationException}} with stacktrace:

on Eager it works correctly
* For me the issue is occurring in all RF versions prior to {{4.2.3}} which
have support for {{rich:pickList}}.
* It means that it is either not regression or I am getting different exception
because of another issue/wrongly set up project.
Ken H., is this the exception you are getting please? If not could you please
check the project and tell me where is the difference with your project ?

> pickList without collectionType results in failure to lazily load
> -----------------------------------------------------------------
>
> 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
>
> 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.
