Hi all,

I would like to programmaticaly create a link between two nodes on the
diagram (in the notation model). None of the nodes have a reference on
the other in the semantic model, so there is no relation between the
notation and the semantic model.

How can I achieve that?

Hello Youmm P.,

Try creating link mapping without any domain model information specified
- pure-design links are supported in GMF-generated diagrams.

Ok it works fine! Thanks, I think I was looking for something too
complex this time...

For the archive, I did something like that (the source and target edit
part are the same, it was just to test):

CreateConnectionViewRequest connectionViewReq =
CreateViewRequestFactory.getCreateConnectionRequest (
XYZElementTypes.Link_3004,
toplevelEditPart.getDiagramPreferencesHint ());

connectionViewReq.setSourceEditPart (editPart);
connectionViewReq.setTargetEditPart (editPart);

CreateConnectionViewRequest.getCreateCommand (connectionViewReq,
editPart, editPart)

Thanks again.

It works fine but the link are not saved in the notation model, so when
I opened again the diagram, they are missing. Any ideas? Saving the
links in a Style?
