function linkTextSet(destId, tf) {
diagram.links.forEach(function (link)
           {
     if (diagramLink.getDestination().getId() === destId)
           diagramLink.setText(tf);
           });
}

I step through the code above and see that diagramLink.setText(tf) is stepped through, but the change never shows on the diagram, even though when I look at the link object I see that the text has changed. Also the diagramLink.setText(tf) is stepped through twice even though it should  only match once.

Looks like the same link twice based on the origin and destination object IDs. In reality the two links originate from the same object, but terminate on two different objects.


thanks
