Trying to visualize the Binary Search Tree with JavaFX. Working IDE is IntelliJ IDEA. Double checked source codes, but couldn't find any missing points or issues which can cause the error.
Whole source code can be seen in the following repo (BinarySearchTreeApplication Folder): https://github.com/af4092/Binary-Search-Tree.git
