When I add PE form palette, it's not being selected. This is not behavior I am seeing in tutorial examples where when Class is created, it's selected in the editor - source.

Is there anything I need to define in order for PE to be selected when it's created?

This is my add() method:

	public PictogramElement add(IAddContext context) {
		IPeCreateService peCreateService = Graphiti.getPeCreateService();
		IGaService gaService = Graphiti.getGaService();
		ObjectType object = (ObjectType) context.getNewObject();
		Font font = gaService.manageFont(getDiagram(), "Arial", 9);
		IDimension dimensions = GraphitiUtil.calculateContainerWidth(object.getName(), font);
		int containerWidth = calculateContainerWidth(dimensions);

		// main container
		ContainerShape containerShape = createMainContainer(context);

		// rounded rectangle
		createRoundedRectangle(context, gaService, containerWidth, containerShape);

		// icon
		createObjectIcon(peCreateService, gaService, object, containerWidth, containerShape);
		IwayType root = ((DesignerDiagramBehavior)getDiagramBehavior()).getModelRoot();

		final ChopboxAnchor newAnchor = peCreateService.createChopboxAnchor(containerShape);
		link(containerShape, object);
		// line
		createHorizontalLine(peCreateService, gaService, containerWidth, containerShape);

		// label
		createObjectLabel(peCreateService, gaService, object, font, containerWidth, containerShape);

		int width = context.getWidth() < MIN_SIZE ? MIN_SIZE : context.getWidth();
		int height = context.getHeight() < MIN_SIZE ? MIN_SIZE : context.getHeight();

		final Connection targetConnection = context.getTargetConnection();
		if (targetConnection != null) {
			gaService.setLocation(containerShape.getGraphicsAlgorithm(), context.getX() - (width / 2),
					context.getY() - (height / 2));

			Anchor oldEndAnchor = targetConnection.getEnd();
			Anchor oldStartAnchor = targetConnection.getStart();


			createConnection(peCreateService, gaService, oldStartAnchor, targetConnection, newAnchor, true);
			createConnection(peCreateService, gaService, newAnchor, targetConnection, oldEndAnchor, false);

		gaService.manageFont(getDiagram(), IGaService.DEFAULT_FONT, IGaService.DEFAULT_FONT_SIZE, true, false);
		// trigger object add event
		try {
			if (ModelHelper.isAdapterObject(object.getType())) {
				DesignerDiagramBehavior designerDiagramBehavior = (DesignerDiagramBehavior)getDiagramBehavior();
				LocalDescriptorProvider localDescriptorProvider = designerDiagramBehavior.getLocalDescriptorProvider();
				com.ibi.configsm.xml.server.ObjectTypeDocument.ObjectType[] flowObjectCategory = localDescriptorProvider.getObjectTypes(object.getType());
				if(flowObjectCategory.length > 0){
					com.ibi.configsm.xml.server.ObjectTypeDocument.ObjectType beanObjectType = flowObjectCategory[0];
					ComponentDescriptor serviceDescriptor = localDescriptorProvider.findServiceDescriptor(beanObjectType);
					designerDiagramBehavior.getEventBus().post(new ObjectActionChangeEvent(null, serviceDescriptor));
		} catch (CoreServicesException e) {
			DesignerUIPlugin.getDefault().logError(e.getLocalizedMessage(), e);
		DiagramEditor editor = (DiagramEditor) PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
		return containerShape;

setting the editor selection from within the add feature should not be required. The graphical element you return in the add feature is used in DiagramBehavior.executeFeature() to select it. The only thing that I could think that prevents this, is the method getSelectionBorder() in the tool behavior provider that can be used to adapt the selected shape.

Or do you override IToolBehaviorProvider.getSelections method and somehow unselect shape?

I don't select border in tool behavior, nor do I override getSelection(), to see if my implementation of tool behavior is at fault, I removed reference to it, but still see the same behavior.
