Accessing Code behind Model [message #1777693]

Hello there,

I am using the xText embedded Editor and want to access the "source code" behind the model.

I access the generated model with this code:

Testfile res = editor.getDocument().readOnly(new IUnitOfWork<Testfile, XtextResource>() {
			@Override
			public Testfile exec(XtextResource resource) throws Exception {
				return EcoreUtil.copy((Testfile) resource.getContents().get(0));
			}
		});

My attempt to get the text behind a model element failed, because the returned node is always null:

ICompositeNode node = NodeModelUtils.getNode(step);
String code = NodeModelUtils.getTokenText(node);

How can I get the text behind the model element?

besides this the question would be why is node null?
of course you should not return eobjects from the readOnly methods.
but i have no clear view of what you are doing

your answer already helped me.
The error was that I was returning a copy of the model with EcoreUtil.copy
Now I am returning the model directly.

Testfile res = editor.getDocument().readOnly(new IUnitOfWork<Testfile, XtextResource>() {
			@Override
			public Testfile exec(XtextResource resource) throws Exception {
				return ((Testfile) resource.getContents().get(0));
			}
		});

But what do you mean with Quote:
