Hi,

Iam trying to add some elements when diagram is created. But those elements are not added/shown in the diagram. Actually elements are getting added to model but not to the notation.

In XXXDiagramUtil class, in createDiagram method iam creating new nodes to the diagram using ViewService.createNode(diagram, element,...

Elements are added to model but not to the notation. How to add notation elements whendiagram is created

Thanks,
Sarath

Hi,

did you try out this request: http://publib.boulder.ibm.com/infocenter/rsmhelp/v7r0m0/index.jsp?topic=/org.eclipse.gmf.doc/reference/api/runtime/org/eclipse/gmf/runtime/diagram/ui/requests/CreateUnspecifiedTypeRequest.html ? It executes the same code that is executed when creating a model element via the palette.

Hi,

There was problem in my model,graph that is why ViewService.createNode is not generating notation element. After fixing errors in my model,graph,map and regenerating code....it started working....ViewService.createNode is creating node/view and diagram is shown with default elements....

model = createInitialModel();
attachModelToResource(model, diagramResource);
CustomElement element ......
model.getElements().add(element);

Diagram diagram = ViewService.createDiagram(model,
XXXX.MODEL_ID,
XXXXX.DIAGRAM_PREFERENCES_HINT);
Node elementNode = ViewService.createNode(diagram, element,
XXXXX.getType(XXXXX.VISUAL_ID),
XXXX.DIAGRAM_PREFERENCES_HINT);
Bounds bounds = NotationFactory.eINSTANCE.createBounds();
bounds.setX(10);
bounds.setY(20);
elementNode.setLayoutConstraint(bounds);

Thanks,
Sarath
