Layered entities example of storing/loading/updating?

[hrstoyanov]

Hello,
I am getting this exception when trying to persist a layered entity. Looking at the "layered-entities" example, it is unclear how entities are to be stored - please show some code

 org.eclipse.serializer.persistence.binary.exceptions.BinaryPersistenceException: Only the identity layer of an entity can be persisted.
