Resolving Proxy EMF Elements

EMF / Ecore / openArchitectureWare

EMF supports cross-referencing between documents; these elements will be provided at runtime as EObjects with eProxyURI set. You can try and resolve the proxy object using EcoreUtil.resolve(EObject, Resource), but this might not always work.

As the EMF book fails to describe, but the newsgroup does, a common mistake is to load the original Resource using a relative URI instead of an absolute URI.

That is:
String filename = "model/test.model";
ResourceSet resourceSet = new ResourceSetImpl();
URI uri = URI.createFileURI(filename);
Resource resource = resourceSet.getResource(uri, true);

Should be:
String filename = new File("model/test.model").getAbsolutePath();
ResourceSet resourceSet = new ResourceSetImpl();
URI uri = URI.createFileURI(filename);
Resource resource = resourceSet.getResource(uri, true);
