At present the PersistencePlugin generates the following default values in its entity beans:

@OneToMany
private Set<Grocery> groceries = new HashSet<Grocery>();

@OneToOne
private Employer employer;

@ManyToOne
private Employer employer = new Employer();

The first one is non-controversial. The second one I would like to be initialized (please please?) as it makes things much easier for the UI. But I understand if you are against that.

But the final one I definitely think should be removed. We should just leave @ManyToOne relationships as 'null' by default. It doesn't make sense to pre-initialize them, even for new entities, because they are meant to point to existing entities.
