Recently，I am working on a project using the source code of Papyrus.
when I select a node of the model,i expect to get the element id.
The sitituation is like this,I can get the name,type et al.However what I want is to locate the element in the file(midel.uml),so I want to get the id.

the core code I write is as below:
List<IGraphicalEditPart> editParts = getSelectedElements();
Iterator<IGraphicalEditPart> it = editParts.iterator();
while(it.hasNext()) {
IGraphicalEditPart editPart = it.next();
if(!(editPart instanceof DiagramEditPart)) {
NamedElementImpl selectedElement = (NamedElementImpl)(editPart.resolveSemanticElement());
System.out.println(selectedElement.getName());
}
...

Can you please give a helping hand?

Hello,

The ID of the element is not accessible in the UML API, as it is not part of the UML specification. To precisely identify an Element in a UML Model, we typically rely on its XMI ID (i.e. serialization ID)

Here's how to retrieve this ID:

Element umlElement = ...
Resource resource = umlElement.eResource();
if (resource != null){
    String id = resource.getURIFragment(umlElement);
    ...
}

Regards,
Camille
