Connection between two figures [message #1715266]

In the diagram above I am trying to create connection between two figures so that connection start and end are at ellipse anchors. Using code below I am able to connect to figures, however, the connection start and end are not static, but dynamic depending on where shape is moved. What should I do to make connection start and end be on my ellipse anchors? I think it has to do with line peCreateService.createChopboxAnchor(componentContainer);, when I set ChopBoxAnchor on the whole Shape I can initiate connection on that Shape, but that is also where connection starts. If I omit it, then my custom anchors become starting points of the connection.

ContainerShape invisibleContainer = createService.createContainerShape(container, true);
ContainerShape componentContainer = createService.createContainerShape(invisibleContainer, true);

Rectangle createInvisibleRectangle = createService.createInvisibleRectangle(invisibleContainer);
gaService.setLocationAndSize(createInvisibleRectangle, 0, 30, container.getGraphicsAlgorithm().getWidth(), 50);
RoundedRectangle containerShape = createService.createRoundedRectangle(componentContainer, 10, 10);
containerShape.setBackground(manageColor(IColorConstant.WHITE));
containerShape.setLineWidth(1);
//containerShape.setStyle(StyleUtil.getStyleForChannelComponentContainer(getDiagram()));
layoutService.setLocationAndSize(containerShape, 5, 5, container.getGraphicsAlgorithm().getWidth() - 10, 40);
		
setColumnIcon(gaService, containerShape, (ColumnType) newObject);
		
link(invisibleContainer, newObject);
link(componentContainer, newObject);
	
peCreateService.createChopboxAnchor(componentContainer);
createAnchor(invisibleContainer, containerShape, AnchorType.LEFT);

if(TableType.SOURCE == tableType){
	createAnchor(invisibleContainer, containerShape, AnchorType.RIGHT);
}
return invisibleContainer;

Alex,

you should keep the chopbox anchor on your shape to enable users to start the connection on the complete shape. Inside your create connection feature you can change the passed create connection context instance and set the anchors you would like to use (e.g. the ones in the ellipses). You will have to cast the ICreateConnectionContext instance to the implementing class to have access to the setters for the anchors.

HTH,
Michael
