Description

Say you have a postLoad callback on an entity that calls a setter on the object, for example:

public void publicCallback(Object entity) {
Artist a = (Artist)entity;
a.setArtistName("Changed");
}

This works if you fetch the object directly with a SelectQuery. But if you fault in the object through a relationship it will call BaseContext.prepareForAccess which has this:

// sanity check...
if (object.getPersistenceState() != PersistenceState.COMMITTED)

{ String state = PersistenceState.persistenceStateName(object .getPersistenceState()); // TODO: andrus 4/13/2006, modified and deleted states are possible due to // a race condition, should we handle them here? throw new FaultFailureException(... }

Since the object is modified (not committed) an exception is thrown. It is valid to allow mutating an object during postLoad.
