title: Method in SceneBuilder
body: <p>I have one problem. I use JavaFX 1 day. When I want to select a Control Class, I can't do it. It doesn't see class to select(If I move file.fxml to a folder that is in a control class, then I can do it) but Intellij does not run programming (java.lang.NullPointerException: Location is required.)</p>
