ArrayOutOfBoundsException: -14 [message #1012325]

i've got an EClass with an EReference

in my database layer (hibernate) i extend the default EMF Class and add a function to map (my old database) to the EMF construct (old db has only one field, whereat the new db will have a list)

 /**
 * <!-- begin-user-doc --> <!-- end-user-doc -->
 * 
 * @generated NOT
 */
public Contact get__hbm__attendant() {
	if (getMoreContacts().size() > 0) {
		return getMoreContacts().get(0);
	}
	return null;
}


/**
 * <!-- begin-user-doc --> <!-- end-user-doc -->
 * 
 * @generated NOT
 */
public void set__hbm__attendant(Contact newContact) {
	Contact oldContact = get__hbm__attendant();
		if (newContact != null && !getMoreContacts().contains(newContact)) {
		try {
			getMoreContacts().add(newContact);
		} catch (Exception e) {
			System.err.println("the exception will be here");
			e.printStackTrace();
		}
	}
		if (eNotificationRequired())
		eNotify(new ENotificationImpl(this, Notification.SET,
				FrameworkPackage.EXCURSION__MORE_CONTACTS, ldContact,
				newContact));
}

this code looks correct to me, can you point me to my mistake? as the following exception gets raised:

Have you changed the model and regenerated it?

Is newContract.eContainer() non null? It looks like it's needed to
remove it from its current container and that this is going astray.

yes i edited and regenerated everything to be sure everything is fine.

removing it from its current container? do you mean a containment? so an contact can only be on one excursion?
i did not specify this. a contact can be standalone or attached to whatever.

the eContainer is sometimes null sometimes not.
if its eContainer is null, all is fine.
if its eContainer is not null the exception raises

the eReference has properties:

changeable: true
container: false;
containment: false
derived: false
ordered: true
resolveProxies: true;
transient: false;
unique: true;
unsettable:false;
volatile: false
bounds 0..*

NOTE: i got an EClass interface MoreContactsBean, which includes the eReference 0..* moreContacts:Contact;
and i defined an EClass Excursion, which got MoreContactsBean as supertype
this should be fine, right? (does not create statics, so every excursion instance has its own ereference to contacts - they do not share one.)

Yes any given object can only be a member of at most one containment
reference.

When I see
org.eclipse.emf.ecore.impl.BasicEObjectImpl.eBasicRemoveFromContainer(BasicEObjectImpl.java:1396) on
the stack, I'm quite sure you're dealing with a containment reference.

Yes it's clear there's an attempt to remove the object from its current
container.

The feature of the list involved is certainly behaving like it's one for
a containment reference.

Yes.

I'm not sure I follow. I can only emphasize that what you're showing in
the stack looks like an EObjectContainmentEList is involved.

okay, to be sure i now looked at the ecore in text mode and searched for containment="true"
this is not set on anything regarding Excursion or Contact.

i remember that i got containments in the beginning. probably this is still left somewhere in the generated files??
(i did not delete my src files (i just hit "generate model code" in the genmodel) as i have quite some generated NOT code in there...

EDIT: looked through the Excursion code, and noticed that getMoreContacts is set to generated NOT (with an EObjectContainmentEList) - which is incorrect

i guess this will fix my problem.

thanks for you rapid help, ed!
your help is solid as a rock ;D

note: even when i regenerate the src its generating a EObjectContainmentEList instead of EObjectResolvingEList

I'm sure if it's generating that, your model it instructing it to do that.
