[forge-issues] [JBoss JIRA] (FORGE-401) PersistencePlugin should not initialize default value for @ManyToOne

[Richard Kennard (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/FORGE-401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651468#comment-12651468 ] 

Richard Kennard commented on FORGE-401:
---------------------------------------

Okay, I've tested this. If you can give me:

	@OneToOne
	private Profile profile;

	public void newProfile() {
		this.profile = new Profile();
		// Bonus points for hooking up any inverse relationship, like:
		// this.profile.setCustomer(this);
	}
	
	public Profile getProfile() {
		return this.profile;
	}

	public void setProfile(final Profile profile) {
		this.profile = profile;
	}

That'll do it.

> 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.
