Embedded Editor wont list references to an external Ecore model [message #1750015]

Hello there,

i followed the tutorial from Christian to link my editor with an external model (https://christiandietrich.wordpress.com/2011/07/17/xtext-2-0-and-uml/)

Its working fine with the generated editor.

Now i want to reuse the editor in an swt component (inside an eclipse) but it wont show the elements from other models. here is what i did:

ArithmeticsActivator arithmeticsActivator = ArithmeticsActivator.getInstance();
Injector injector = arithmeticsActivator.getInjector(ArithmeticsActivator.ARITHMETICS_DSL);
XtextResourceSet XtextResourceSet = injector.getInstance(XtextResourceSet.class);
XtextResourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
xtextResource = (XtextResource) XtextResourceSet.createResource(URI.createURI(someObjectFromTheOtherModel.eResource().getURI().trimSegments(1)+"/temp.arithmetics"));

comp.setLayout(GridLayoutFactory.fillDefaults().margins(1, 1).create());

EmbeddedEditorFactory factory = injector.getInstance(EmbeddedEditorFactory.class);
EmbeddedEditor embeddedEditor = factory.newEditor(getResourceProvider()).showErrorAndWarningAnnotations().withParent(comp);
EmbeddedEditorModelAccess partialEditorModelAccess = embeddedEditor.createPartialEditor(false);
embeddedEditor.createPartialEditor();

The Editor shows up and works just fine, but when i try to link to an existing element (space + strg) nothing shows up.

Thx for your time.

Yes, and i tryed to use a URI besides the existing model, see:

xtextResource = (XtextResource) XtextResourceSet.createResource(URI.createURI(someObjectFromTheOtherModel.eResource().getURI().trimSegments(1)+"/temp.arithmetics"));

you should use IResourceSetProvider to obtain a project spüecific resourceset

Hello Christian,

thx for your reply and time. Realy appreciate it.

Can you give me a short example? I have one Eobject from the model i would like to reference

My Problem is that factory.newEditor(getResourceProvider()) a XTextResourceSet requires

i also tryed to load the other model directly into my resource set, sadly it doesent work either

IResourceSetProvider.get(project) gives you one (maybe downcast)

i tryed that already:

XtextResourceSetProvider xtextResourceSetProvider = injector.getInstance(XtextResourceSetProvider.class);
IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject("Test");
XtextResourceSet XtextResourceSet = (org.eclipse.xtext.resource.XtextResourceSet) xtextResourceSetProvider.get(project);
// XtextResourceSet XtextResourceSet = injector.getInstance(XtextResourceSet.class);
xtextResource = (XtextResource) XtextResourceSet.createResource(URI.createURI(someObjectFromTheModel.eResource().getURI().trimSegments(1) + "/asdsad.arithmetics"));
Resource modelResource = XtextResourceSet.createResource(URI.createURI(someObjectFromTheModel.eResource().getURI().toString()));
try {
xtextResource.load(Collections.EMPTY_MAP);
modelResource.load(Collections.EMPTY_MAP);
} catch (IOException e1) {
e1.printStackTrace();
}
return xtextResource;

My URI looks like: file:/C:/Projekte/[...]/runtime-EclipseApplication/Test/mymodel.domain and file:/C:/Projekte/[...]/runtime-EclipseApplication/Test/asdsad.arithmetics

The code i posted in the first Comment of this topic is nearly the hole code i have. The first 5 lines are Wrapped in a method that returns an IEditedResourceProvider (named getResourceProvider()).

Wow thank you Christian, i hardcoded the URIs to the platform-format and it works now. Can you explain that to me?

yes xtext behaves differently in standalone and eclipse mode and in eclipse mode everything is tied to projects
and emf uris for project look like platform:/resource/project/...
