This issue occured with all anchor types if they use a polyline as GA, since GFChopboxAnchor only dealt with Polgon intersections. Checked-in a fix to head. Part of Graphiti Indigo 0.8.0 |
Build Identifier: 20100917-0705 This methode creates for a BoxRelativeAnchor a graphics algorithm private void createGraphicalPort(final BoxRelativeAnchor boxAnchor) { IGaService gaService = Graphiti.getGaService(); Style style = styleProvider.getStyle(); //Rectangle rec = gaService.createRectangle(boxAnchor); Polyline poly = gaService.createPolyline(boxAnchor ,new int[]{0, PORT_SIZE / 2, PORT_SIZE, PORT_SIZE / 2}); //rec.setStyle(style); poly.setStyle(style); //gaService.setLocationAndSize(rec, 0, 0, PORT_SIZE, PORT_SIZE); gaService.setLocationAndSize(poly, 0, 0, PORT_SIZE, PORT_SIZE); } when the rec is used then it works. The create / add connection feature is nearly the same as in the tutorial. And here the exception. After this exception eclipse / graphiti throws other exceptions. It can't be add, move, change vertexes. The diagram can't be resized (eclipse yes but the inner window has got the same size as before) java.lang.NullPointerException at

BoxRelativeAnchor boxAnchor 2.create Polyline poly = gaService.createPolyline(boxAnchor ,new int[]{0, PORT_SIZE PORT_SIZE, PORT_SIZE / 2}); //for the boxAnchor 3. try to make a connection for two BoxRelativeAnchor who has got a polyline as graphics algorithm.
