> 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.
> The stack trace for the exception is below:
