Hey there,
I posted a similar question over on the EMF forum as I thought it might be more applicable but I was wondering if anyone here has had any luck using the code from the TutorialUtils.java file in the Drill-Down example.
I am getting a FileNotFoundException on trying to load a resource from a file.
This is being derived from the Drill-Down Feature which I have implemented in a very similar fashion as the tutorial. The one big difference between my system and the tutorial is that I separate my diagram from my model file.
The stack trace I am getting is:
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: java.io.FileNotFoundException: /egsc_test3/src/diagrams/Test47.diagram (No such file or directory)

at org.eclipse.jface.action.ActionContributionItem.fill(ActionContributionItem.java:291)
Above, /egsc_test3 is the project. Test47.diagram is the diagram file I am trying to load.
The error is derived from the getDiagramFromFile method, which is essentially unchanged. Actually almost all of the TutorialUtil code that I have used is unchanged for the most part.
private static Diagram getDiagramFromFile(IFile file, ResourceSet resourceSet) {
// Get the URI of the model file.
final URI resourceURI = getFileURI(file, resourceSet);
// Demand load the resource for this file.
Resource resource;
try {
resource = resourceSet.getResource(resourceURI, true); // ERROR FROM HERE
if (resource != null) {
// does resource contain a diagram as root object?
final EList<EObject> contents = resource.getContents();
for (final EObject object : contents) {
if (object instanceof Diagram) {
return (Diagram) object;
}
}
}
} catch (final WrappedException e) {
e.printStackTrace();
}
return null;
}
I have tried both loading the model file (which has an extension ".egsn") and the diagram file (extension ".diagram"). Both derive the same result.
Anyhow, I was just wondering if anyone had run into the same problem.
Thanks,
Joe

Problem solved...
in the function getFileURI I needed to use
URI resourceURI = URI.createPlatformResourceURI(pathName, true);
instead of
... URI.createFileURI(pathName);
I did not test it without the decode option, so I am not certain if that is necessary.
