Hi Masija,
please do yourself a favor and don't ever use the standalone setup in an
eclipse environment - it's called StandaloneSetup for good reasons ;-)
Furthermore you should - if you want to edit an actual file - use the
platform:/resource uri of that file.
Please try to use something along these lines:
@Inject
XtextResourceSetProvider resourceSetProvider;
XtextResourceSet resourceSet =
resourceSetProvider.get(projectOfEnclosingIResource)
URI uri =
URI.createURI("platform:/resource/projectName/path/in/project.dslExtension")
resourceSet.getResource(..)
I suggest to learn more about dependency injection and how EMF works.
Regards,
Sebastian

Hi Sebastian, again a question from me...
I can't get your snippets fo work corectly. I have injected an XtextResourceSetProvider. After that I changed the createResource() method i posted above to:
IEditedResourceProvider resourceProvider = new IEditedResourceProvider() {
@Override
public XtextResource createResource() {
try {
URI fileURI = editingDomain.getResourceSet().getResources().get(0).getURI();
IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject(fileURI.segment(1));
ResourceSet resourceSet = resourceSetProvider.get(project);
Resource resource = resourceSet.createResource(URI.createURI("somefile.dsl"));
return (XtextResource) resource;
} catch (Exception e) {
return null;
}
}
};
EmbeddedEditorFactory factory = injector.getInstance(EmbeddedEditorFactory.class);
handle = factory.newEditor(resourceProvider).withParent(parent);
partialEditor = handle.createPartialEditor(true);
// set the input of the document in the popup editor to the value, stored in the modelA
handle.getDocument().set(StringValueOfModelA);
But this doesn't change anything... Perhaps an explanation what I am trying to do. I have a model (ModelA) which has some EString properties. In the editor of this model, i embedded an Editor for my xtext dsl to be able to input correct statements of my grammar. This grammar references another xtext model (ModelB), which is in the same project as ModelA.
These crossreferences are not possible... So I dont want to edit an actual file, I want to edit some Strings in ModelA, which should be interpreted in respect to my xtext grammar. These strings shouldnt be saved somewhere in the workspace.
Perhaps your hint, how EMF works will be promising... I have started to read the EMF book, but haven't got the big picture to understand what I am doing wrong.
Perhaps you could comment again in this topic and help me 
Regards
Masija
