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.
