How to set model.getDocumentNode when loading multiple documents?

I load multiple models from multiple converted revit files in the viewer. In each of these models I put points associated to selected element. To be able to reuse these points later, I need:

  1. Which revit document it was taken from -> models[x].myData.urn : ok
  2. Which view (model) from revit document it was taken from -> model.getDocumentNode returns null (which is not the case when I load a single model with viewerApp). This leads node.model.getDocumentNode().data.guid which is guid of the view to be not reachable. ko
  3. Dbid -> present in selection event: ok
  4. Guid -> I build a 2 ways mapping table (dbid<->guid) to get what I need : ok (open to more straightforward ways, but ok)

Main issue is the 2nd point, How to set model.getDocumentNode when loading multiple models in the viewer?

Thank you,

You could collect the document URN and the model GUID during the loading process:

function load(urn) {
    viewerApp.loadDocument(
        'urn:' + urn,
        function onDocumentLoadSuccess(doc) {
            const viewables = viewerApp.bubble.search({ 'type': 'geometry' });
            if (viewables.length > 0) {
                const path = doc.getViewablePath(viewables[0].data);
                const viewer = viewerApp.getCurrentViewer();
                const options = { /* your options */ };
                viewer.loadModel(path, options, function onModelLoadSuccess(model) {
                    model._myURN = urn;
                    model._myGUID = viewables[0].data.guid;
                });
            }
        }
    );
}
