updating emf using lines below does not update the node model as F3 "go to declaration" does not work

for (EStructuralFeature crossRef : eStructuralFeatures) {
if(crossRef instanceof EReference) {
if (crossRef.getName().equals("aliasName")) {
declarationR.eSetDeliver(false);
declarationR.eSet(crossRef, alias);
}
}
}

any clue?

Why did you open another topic for this?

As I said in the previous topic: Editing the EMF model in the BuilderParticipant has no effect on the editor.

Without knowing your use case:

- use scoping or
- use LazyLinker#afterModelLinked

The node model will not be kept in sync if you do plain changes to the
EMF model. Use IXtextDocument.modify if you need that, but it is only
for interactive usecases. emf.Resource.save(..) will write changed
contents back to text and you can obtain a node model from that one.

Best,
Sebastian

So what is written in the file is
Alias T;
Declaration T;
Any clue?
