| Autoboxing in EMF fails [message #417844] |
Wed, 26 March 2008 19:44  |
|
Hi,
I read once that EMF 2.3 had autoboxing implemented.
Does any know why the following doesn't work?
Best regards, Lars
Model:
package auto;
import java.lang.String;
import org.eclipse.emf.common.util.EList;
import org.eclipse.emf.ecore.EObject;
import java.util.List;
/**
*
* @model
*/
public interface IBox extends EObject {
/**
*
* @model containment = "true"
*/
public EList<String> getNames();
}
Test code:
package test;
import auto.AutoFactory;
import auto.IBox;
import auto.impl.AutoFactoryImpl;
public class Main {
/**
* @param args
*/
public static void main(String[] args) {
AutoFactory factory = AutoFactoryImpl.eINSTANCE;
IBox box = factory.createIBox();
box.getNames().add("Moin");
}
}

Hi Ed,
The compliance level for EMF and Java is set to 6.0 and I receive the
following error:
Exception in thread "main" java.lang.ClassCastException: java.lang.String
cannot be cast to org.eclipse.emf.ecore.InternalEObject
at org.eclipse.emf.ecore.util.EcoreEList.inverseAdd(EcoreEList. java:267)
at
org.eclipse.emf.common.notify.impl.NotifyingListImpl.addUniq ue(NotifyingListImpl.java:318)
at org.eclipse.emf.common.util.BasicEList.add(BasicEList.java:6 26)
at test.Main.main(Main.java:15)
Best regards, Lars

Lars,
Oh. I see you've set containment="true" which makes EMF think this
feature is an EReference rather than an EAttribute; hence you can only
add EObjects to it and java.lang.String isn't an EObject. You need to
remove the containment="true"

What's not working? You're sure you've set source compatibility to 5.0
for the JDT's preferences and you've set the GenModel's Compliance Level
to 5.0?
