Exception running application com.itemis.gef.tutorial.mindmap.visuals.MindMapVisualApplication
The above stack trace result is generated after executing every single step of Part 1 of the tutorial provided on the website.
I did a complete code coverage and the error seems to generate from the part of the code in "MindMapVisualApplication"
**Connection conn = new MindMapConnectionVisual();
conn.setStartAnchor(new DynamicAnchor(node, new ChopBoxStrategy()));
conn.setEndAnchor(new DynamicAnchor(node2, new ChopBoxStrategy()));
root.getChildren().addAll(conn, node, node2);
primaryStage.setResizable(true);
primaryStage.setScene(new Scene(root, 1024, 768));
primaryStage.setTitle("This is an JavaFX Environment Test");
primaryStage.sizeToScene();
primaryStage.show();**
and also the whole "MindMapConnectionVisual" class.
I am running the on Eclipse IDE - 2018.12 with JavaSE 1.8 and Javafx-sdk-11.0.2
Would appreciate if anyone can provide me with a solution to this error.
