LazyInitializationException in RESTORE_VIEW (incorrect PersistentSet instance creation)

I started using IceFaces and ran into a problem while trying to support drag'n'drop.

IceFaces 2.0.0
JSF 2.0
Mojarra 2.0.2 (FCS b10) (JSF reference implementation)
Spring 3.0.3
Hibernate 3.5.1-Final
JPA 2.0 (with OpenEntityManagerInViewFilter)

LazyInitializationExceptionDrop problem . My first conclusion was the incorrect context lifecycle management settings, but after several hours of playing with the settings, dependencies and debugging, I found a strange thing: the JSFimplementation creates an instance PersistentSetby reflection with the default constructor (!) B RESTORE_VIEW phaseand tries to add values ​​to it. This action invokes LazyInitializationExceptionbecause it PersistentSetis created as a simple type collection ArrayListand is not configured properly (the session is not established).

    }
    catch (Exception e) {
