INode of unresolvable proxy EObjects [message #1745080]

Hello,

is it possible to get the INode of an unresolvable element? NodeModelUtils.getNode(..) returns null. I've started iterating from the root Node and compared their semantic element with the proxy EObject, but their fragments differ:
- unresolvable objects fragment: #|4
- List<INode> feature = NodeModelUtils.findNodesForFeature(EObject, Feature): ... (gathered the Semantic Element) #//@nodes.0

So i can't match them, to find the corresponding INode. What is the appropriate way to achieve this? Thanks in advance.

Best regards
Mehmet

Hi

can you tell what you want to do with the node? NodeModelUtils.findNodesForFeature(EObject, Feature) should give you the node

of course you could do the same as the linking does

org.eclipse.xtext.linking.lazy.LazyLinkingResource.getEObject(String)

if (r instanceof LazyLinkingResource) {
LazyLinkingResource lazyLinkingResource = (LazyLinkingResource)r;
if (lazyLinkingResource.getEncoder().isCrossLinkFragment(lazyLinkingResource, eProxyURI.fragment())) {
Triple<EObject, EReference, INode> triple = lazyLinkingResource.getEncoder().decode(lazyLinkingResource, eProxyURI.fragment());
System.out.println(triple.getThird().getText());
}
}

but i doubt thats neccessary

I am viewing the objects in a tree viewer and the unresolved objects are visible but don't contain any information. I want to show the text of these INodes + "(Proxy)" to inform the user, that these objects could not be resolved. The code above worked for me. Thank you.
