Hi there,
I've a little problem that I can't explain ...
On Eclipse Indigo, I realized a Metamodel MM. I would like to create some models conformed to this metamodel.
Assuming that model and model.edit plug-in are already generated from the genmodel.
Here is the simplest test code I tried, based on the "Hello World" plug-in projet sample :
public void run(IAction action) {
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IProject project = root.getProject("test");
if (project.exists() && project.isOpen()) {
URI uri = URI.createPlatformResourceURI("/test/my.mm", true);
Resource res = new MMResourceImpl(uri);
res.getContents().add(MMFactory.eINSTANCE.createMMModel());
try {
res.save(Collections.EMPTY_MAP);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
MessageDialog.openInformation(
window.getShell(),
"Test",
Hello World);
}
}
The file my.mm is created, but is empty, and a java.lang.UnsupportedOperationException is raised :

Using EditingDomain, ResourceSet produced the same result. Tests have been produced on Debian and MacOS.
I don't understand anymore ...
Is there any idea ?
