the class DefaultDiagramViewer method onOpen.

@Override
protected void onOpen(final Diagram diagram) {
    final Annotation qualifier = definitionUtils.getQualifier(diagram.getMetadata().getDefinitionSetId());
    canvasPanel = InstanceUtils.lookup(canvasPanelInstances, qualifier);
    canvas = InstanceUtils.lookup(canvasInstances, qualifier);
    canvasHandler = InstanceUtils.lookup(canvasHandlerInstances, qualifier);
    mediatorsControl = InstanceUtils.lookup(mediatorsControlInstances, qualifier);
    selectionControl = InstanceUtils.lookup(selectionControlInstances, qualifier);
    shapeListener = new DefaultCanvasShapeListener(Collections.singletonList(mediatorsControl));
    canvas.addRegistrationListener(shapeListener);
    elementListener = new DefaultCanvasElementListener(Collections.singletonList(selectionControl));
    canvasHandler.addRegistrationListener(elementListener);
