Hello,
I have tried to follow the instructions based on https://www.eclipse.org/sirius/doc/specifier/general/Model_Operations.html#created_edge_view

but I am getting a NullPointer on function createEdgeView on the line DDiagramSynchronizer dDiagramSynchronizer = new DDiagramSynchronizer(interpreter, parentDDiagram.getDescription(), extPackage);

the property parentDDiagram is null

Can you provide an example how to Drop an edge from the Model Explorer?

Hi,

I am not sure to understand your need. Dropping an edge does not mean something to me.
If you have a semantic element that represents an edge then you have a mapping in your diagram to represent it and as soon as the semantic element is created, then it will be visible without drag&drop.

Hi Pierre,
thx for the quick reply.
I was getting a bit confused with the edge synchronization. I had it as "Not synchronized" as I would like to remove Edges from my diagram "soft delete" and I tried to implement a Container Drop and add Create Edge View.
I was getting the NullPointer exception, but once I added a Change Context with var:element and then added the Create Edge View the issue was resolved.
