Ken H updated RF-12608:
-----------------------

    Description: 
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:
