Can anyone take a look at this code I'm using to try to generate an edge
between two nodes? It appears to be erroring out on
CreateRelationshipRequest, but I don't know why. Please excuse the
horrible method for getting targetEditPart, but I was concentrating on the
edge generation; both source and target are valid EditParts just below the
root level.
Thanks for any and all help, I've been trying to figure out how to
programmatically generate an edge for two days now.
final EditPart sourceEditPart = this.getParent();
final EditPart targetEditPart =
(EditPart)getParent().getParent().getChildren().get( 1 );
final PreferencesHint prefsHint = PreferencesHint.USE_DEFAULTS;
final ElementTypeRegistry typeRegistry = ElementTypeRegistry.getInstance();
final IElementType edgeType = typeRegistry.getElementType(
ShapesPackage.Literals.CONNECTION );
CreateRelationshipRequest crr = new CreateRelationshipRequest(
(EObject)sourceEditPart,
(EObject)targetEditPart, edgeType );
CreateElementRequestAdapter cera = new CreateElementRequestAdapter( crr );
ViewService.getInstance().createEdge(cera, getNotationView(),
ConnectionEditPart.VISUAL_ID + "", -1,
true, prefsHint);
