public class TableRowAlreadyManagedEvent
extends ManagedEntityEvent

The TableRowAlreadyManagedEvent indicates that a given database table row is managed by an entity that was already bound to the current Persistence Context.

When having multiple entities mapped to the same database table, it's important to load at most one entity that manages a given record. Otherwise, you could end up having to entity objects with different state synchronizing the same table record at flush time.
