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:

* However, I am not sure whether that is the same exception as reported ?
* When I change
[this|https://github.com/jhuska/RF-12608/blob/master/src/main/java/org/ric...]
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.
