I need to add an extra EAttribute to an eObject.
For doing this, I extend the eClass of this eObject using Dynamic EMF. I succeed doing that.
Then, I added eAttribute to this dynamically created eClass. Then, the extended eObject is created successfully.
Now, I want to add all the values of EStructuralFeatures from the originalObject to the extendedObject.
The following method fails to do that: What is wrong in this method?
public static EObject clone( EObject originalObject,EObject extendedObject) {
for ( Iterator i = extendedObject.eClass().getEStructuralFeatures().iterator(); i.hasNext(); )
{
EStructuralFeature feature = (EStructuralFeature) i.next();
extendedObject.eSet( feature, originalObject.eGet( feature ) );
}
return extendedObject;
}

Hi,
In addition to Ed's comment, it is probably also necessary for the
other connected clients to have the same package available locally in
their VMs. Moreover, if you're dealing with dynamically created Ecore
models, although CDO supports dynamic Ecore, it does not support
changes to an Ecore model once that model has been published to it.
Cheers,
Christian
